The Concord Alliance Treaty Organization (CATO), formerly known as the Tripartite Treaty Organization (TTO), is an international military and political alliance between Natopia, Nouvelle Alexandrie, Oportia, Vegno, East Zimia and the Wallis Islands, and Aerla. Established on 9.X.1731 AN as the TTO by its three founding members, the organization underwent significant reforms and expansion during the Butter Cow City Summit from 24.XIII to 13.XIV.1734 AN, where it was reorganized into CATO as a result of the Concord Alliance Treaty. The alliance expanded for the first time in 1738 AN with the admission of Vegno following the State Visit of King Sinchi Roca II to Vegno, and again in 1751 AN and 1752 AN with the accession of East Zimia and the Wallis Islands and Aerla respectively.

CATO serves as a system of collective security, whereby its independent member states agree to mutual defense in response to an attack by any external party. The organization also encourages cooperation on trade, defense, and security issues to build trust and prevent conflict among member nations. Since its reformation in 1734 AN, CATO has expanded its original focus on collective military defense to include cooperation in economic, technological, and cultural spheres.

The organization operates through a deliberately decentralized structure, with its principal headquarters at Concord House in Lindstrom, Natopia, and National Coordination Offices in the capital of each member state. CATO operates on the principle of consensus decision-making, where all member states must agree for any major decisions to be made. The organization's highest decision-making body is the Concord Council, whose presidency rotates annually among member states. Day-to-day operations are coordinated by the Secretary-General, who chairs the Concord Council and directs the CATO Secretariat.

While maintaining strong ties with the Raspur Pact, from which many of its operational standards are derived, CATO has evolved into a distinct entity focused on deepening integration among its members. The organization has established various specialized agencies and programs, reflecting its approach to security and cooperation. CATO is also affiliated with other international bodies such as the Community of Goldfield and the Euran Economic Union. The alliance completed its integrated communications infrastructure in 1742 AN, establishing a quantum-encrypted command and control network spanning all member territories.

Background

The CATO emerged from the complex geopolitical landscape of the early 1730s AN. As members of the Raspur Pact, Natopia, Nouvelle Alexandrie, and Oportia had cultivated deep political, cultural, economic, and military ties over the years. However, the outbreak of the Shiro-Benacian conflict in 1730 AN raised significant concerns among these nations, prompting them to seek additional safeguards for their mutual interests. This led to the formation of the Tripartite Pact and its implementing body, the Tripartite Treaty Organization (TTO), as a means of cementing their ties and cooperation in the eventuality that the conflicts within the Raspur Pact would lead to its dissolution or incapacitation.

In the years following its establishment, the TTO maintained its connections with the Raspur Pact. However, by 1734 AN, it had become increasingly clear that the larger alliance was beset by paralysis, lack of leadership, and internal divisions. The governments of the TTO member states, recognizing that the situation was unlikely to improve and that the Raspur Pact had effectively become moribund, began to formulate plans for a post-Raspur Pact world, a scenario they had previously considered improbable.

In response to this geopolitical shift, the TTO members initiated discussions to open the alliance to other nations, adopt standards compatible with those of the Raspur Pact in military and organizational affairs, and explore avenues for further cooperation and integration. Federal Representative Galilea Montijo of Oportia proposed a summit to address these issues. Natopia offered to host the event, and Nouvelle Alexandrie enthusiastically endorsed the initiative. This led to the convening of the Butter Cow City Summit in Sororiya, Natopia.

The summit revealed that all three nations had been independently preparing for a post-Raspur Pact landscape. Recognizing the TTO as their most viable platform for continued cooperation, the member states worked diligently to craft agreements and treaties aimed at reforming and expanding the organization. Key outcomes of the summit included a commitment to exploring the establishment of a common currency, initiatives to establish common standards across various sectors, and plans for closer cooperation in multiple fields to strengthen international bonds.

During the summit, Empress Vadoma I of Natopia suggested renaming the alliance to "the Concord Alliance." This proposal was met with approval from the other delegations. The name "Concord" was chosen to symbolize the harmony and agreement among the member states, as well as their shared vision for a peaceful and prosperous future. The term "Alliance" was retained to emphasize the strong bonds and mutual commitments between the nations.

The Butter Cow City Summit culminated in the signing of the Butter Cow City Agreements, which included the Concord Alliance Treaty, outlining the new structure and objectives of the reformed organization, and the Raspur Pact Harmonization Accords, ensuring compatibility with existing Raspur Pact standards and facilitating a smooth transition. These agreements formed the foundation for the transformation of the Tripartite Treaty Organization (TTO) into the Concord Alliance Treaty Organization (CATO).

This evolution represented not just a change in name, but a significant expansion of the alliance's scope, objectives, and potential for future growth. The reformed organization was designed to be more adaptable, open to new members, and committed to deeper integration among its constituent nations. By maintaining compatibility with Raspur Pact standards while simultaneously expanding its mandate, CATO positioned itself as a key player in the evolving international order, ready to face the challenges and opportunities of a post-Raspur Pact world.

Purpose and objectives

The primary aim of CATO is to ensure common stability, security, and economic prosperity through cooperation, within the Raspur Pact as a common basis of cooperation and further integration. Objectives include:

• Ensuring mutual defense and security preparedness through coordinated military planning and response;
• Fostering alignment of foreign policies and coordinated responses to international challenges;
• Facilitating trade, investment, and economic cooperation among member states;
• Promoting free movement of citizens and cultural exchange between member nations;
• Contributing to global peace and security through collective action and diplomatic coordination.

Treaties and agreements

Tripartite Pact

The Treaty of Mutual Defense and Cooperation (known as the Tripartite Pact) originally signed at the Lindstrom Summit in 1731 AN were repudiated and replaced with a new set of treaties that would allow the organization to transition to the Concord Alliance Treaty Organization and pass on its institutional legacy to the newly renewed alliance.

Concord Alliance Treaty

The Concord Alliance Treaty, also known as the Butter Cow City Treaty, forms the legal basis of, and is implemented by, the Concord Alliance Treaty Organization. The treaty was signed in Butter Cow City, Natopia. This treaty repudiated and replaced the original Tripartite Pact Treaty and passed its assets and responsibilities to CATO as its successor organization.

Butter Cow City Agreements

The Butter Cow City Summit resulted in three significant accords:

1. Concord Alliance Treaty: Outlining the new structure and objectives of CATO;
2. Raspur Pact Harmonization Accords: Ensuring CATO's compatibility with the existing Raspur Pact.

Concord Intelligence Sharing Agreement

The Concord Intelligence Sharing Agreement, signed in 1735 AN, establishes protocols for the exchange of intelligence information between member states. The agreement created the framework for joint intelligence operations and shared threat assessments, which proved particularly valuable during the Fourth Euran War.

Structure

The Concord Alliance Treaty Organization (CATO) operates through a deliberately decentralized organizational structure established under the flexible provisions of the Concord Alliance Treaty. Article 7 of the Treaty empowers the Concord Council to establish committees and organizational arrangements as needed, which has enabled the development of a distributed governance model that gives each member state a meaningful stake in the alliance's operations.

Headquarters and offices

Principal headquarters

The principal headquarters of CATO is Concord House in Lindstrom, Natopia. Originally known as the Silverlight Palace, the building was acquired by CATO in 1734 AN to serve as its central administrative and diplomatic hub. Concord House hosts the offices of the Secretary-General and Deputy Secretary-General, the central Secretariat staff, the Situation Center for monitoring global security developments, and facilities for Concord Council meetings.

National Coordination Offices

Each member state hosts a National Coordination Office (NCO) in its capital city. These offices serve as the primary liaison between CATO and the host nation's government, coordinate alliance activities within the host nation, support visiting delegations and personnel, and maintain local administrative and communications infrastructure connected to the CATO Integrated Communications Network.

Concord Council

The Concord Council is the highest decision-making body of CATO, composed of the heads of state or their designated representatives from each member state. The Council is responsible for strategic decisions, including setting the alliance's direction, approving major policies, overseeing the implementation of CATO agreements, and coordinating the alliance's response to international challenges. Decisions are made by consensus to ensure equal representation and participation of all member states.

Council presidency

The presidency of the Concord Council rotates annually among member states in order of accession to the alliance. The President of the Council is responsible for setting the agenda for Council meetings, chairing Council sessions during their term, representing the Council in ceremonial functions, and coordinating with the Secretary-General on alliance priorities. The rotation ensures that each member state has regular opportunity to shape the Council's agenda and host its proceedings.

Defense Coordination Committee

The Defense Coordination Committee, established under Article 4 of the Concord Alliance Treaty, serves as CATO's principal military planning and coordination body. This committee is responsible for providing military advice to the Concord Council, developing military strategies and policies, overseeing the implementation of defense decisions, and coordinating military operations among member states. The committee coordinates regular joint military exercises, oversees interoperability initiatives, and establishes common military standards across the alliance's armed forces. The committee regularly reports to the Concord Council on the alliance's military preparedness and makes recommendations for enhancing collective defense capabilities.

The chairmanship of the Defense Coordination Committee rotates on a two-year cycle among the three founding members, reflecting their larger military contributions and the need for continuity in defense planning.

Concord Alliance Defense Command

The Concord Alliance Defense Command (CADC) operates under the authority of the Defense Coordination Committee and is tasked with planning and executing joint military operations and exercises. CADC coordinates the integrated air defense system of the alliance, develops common military standards, and facilitates interoperability among member states' armed forces. The CADC is led by a Supreme Allied Commander, appointed by the Concord Council based on the Defense Coordination Committee's recommendations.

The CADC maintains its headquarters at Concord House in Lindstrom, with forward command elements distributed among the Continental Theatre Commands. The Supreme Allied Commander position rotates among the founding members on a three-year cycle, though operational circumstances may extend or modify individual tenures.

Economic Coordination Committee

The Economic Coordination Committee serves as CATO's primary body for fostering economic integration and cooperation among member states. Established under Article 5 of the Concord Alliance Treaty, the committee oversees the implementation of the alliance's free trade framework. It plays a role in harmonizing regulatory standards across member states while respecting their individual national frameworks.

The committee's mandate includes facilitating the removal of barriers to trade, coordinating investment policies, and establishing common standards for economic cooperation. Through regular consultations and policy reviews, the committee works to ensure the smooth flow of goods, services, and capital among member states. When disputes arise between member states regarding trade or economic matters, the committee serves as the primary forum for resolution, employing established protocols to mediate and resolve conflicts. Additionally, the committee monitors economic trends within the alliance, produces regular analyses of the integrated economy, and makes recommendations to the Concord Council for further economic integration initiatives.

The Economic Coordination Committee maintains its primary offices in Cárdenas, reflecting Nouvelle Alexandrie's role as the alliance's largest economy, with liaison offices in each National Coordination Office.

Political Coordination Committee

The Political Coordination Committee, established under Article 6 of the Concord Alliance Treaty, functions as the central platform for aligning the foreign policies and diplomatic initiatives of CATO member states. The committee facilitates regular consultation and coordination on international affairs, working to develop unified positions on key global issues affecting the alliance's interests. Through its ongoing work, the committee helps member states present a coherent and unified diplomatic front in international forums while maintaining their sovereign decision-making capabilities. The committee plays a role in crisis response, coordinating member states' reactions to international developments and ensuring consistent messaging across the alliance. It maintains continuous diplomatic channels between member states, allowing for swift consultation and response to emerging global challenges. The committee also oversees the implementation of CATO's framework for political cooperation, including initiatives for free movement of citizens between member states and coordination of responses to security threats. Regular meetings at various diplomatic levels ensure ongoing alignment of political objectives and strategies among member states, while special sessions can be convened to address urgent international developments requiring immediate coordination.

The Political Coordination Committee rotates its meeting locations quarterly among member capitals, ensuring regular diplomatic engagement across the alliance.

Secretariat

The Secretariat is the administrative arm of CATO, led by the Secretary-General, who is appointed by the Concord Council for a four-year term, renewable once. The Secretary-General oversees the daily operations of CATO, acts as the principal spokesperson, and manages the alliance's budget and personnel. A Deputy Secretary-General assists the Secretary-General and acts in their stead when necessary.

By convention, the Secretary-General and Deputy Secretary-General are drawn from different member states, and the positions alternate between founding and expansion members where practicable. This practice ensures broad representation in the alliance's senior leadership.

Structure of the Secretariat

The Secretariat is composed of departments correlating to the major spheres of alliance activity. While the central Secretariat is located at Concord House, several departments maintain their primary operations in other member capitals based on functional alignment and expertise.

Department	Function	Primary Location
Department of Defense Coordination	Liaising between member states' military establishments and the Concord Alliance Defense Command; coordinating joint exercises and intelligence sharing	Concord House, Lindstrom
Department of Economic Affairs	Overseeing free trade provisions; monitoring economic trends; advising on fiscal harmonization	Cárdenas, Nouvelle Alexandrie
Department of Legal Affairs	Handling legal harmonization; advising on extradition matters; resolving legal disputes within the alliance	Concord House, Lindstrom (Moving to Noursala, Aerla after 1755 AN)
Department of Political Affairs	Coordinating foreign policy alignment; managing diplomatic communications	Vanie, Oportia
Department of Public Diplomacy	Managing public communications; coordinating media relations; overseeing visitor programs	Cossa, Vegno
Department of Technology and Standards	Overseeing technical standardization; managing communications infrastructure; coordinating research initiatives	Cárdenas, Nouvelle Alexandrie

Current leadership

Position	Holder	Term	Notes
Secretary-General	Silvio Gianni Linard	1752 AN - present	First Secretary-General from an expansion-era member state following Oportia's restoration to democratic governance
Deputy Secretary-General	Jacqueline d'Alessio y Venegas	1752 AN - present

Concord Parliament

The Concord Parliament serves as the deliberative assembly of CATO, providing a forum for popular participation in alliance decisions. Modeled on the Raspur Pact Parliamentary Assembly, the Parliament is composed of delegations from each member state's legislature, allocated proportionally by population with a minimum representation guaranteed to smaller members. The Parliament meets in regular sessions to debate alliance policies, review agreements, and adopt non-binding resolutions on matters of common concern. While the Parliament's decisions are advisory rather than binding, its recommendations carry political weight and inform the deliberations of the Concord Council.

Sessions and hosting

The Concord Parliament holds two regular sessions annually. The Spring Session is held in the capital of the member state holding the Council presidency, while the Autumn Session rotates independently among member capitals. This arrangement ensures that Parliament sessions are distributed across the alliance and that smaller member states have regular opportunity to host parliamentary proceedings regardless of the Council presidency rotation.

Session Type	Frequency	Host Determination	Typical Duration
Spring Session	Annual (III-IV)	Council presidency holder	10-14 days
Autumn Session	Annual (XI-XII)	Independent rotation	10-14 days
Extraordinary Session	As needed	Concord Council designation	Variable

Continental Theatre Commands

CATO's military structure is organized through Continental Theatre Commands, each responsible for coordinating alliance military activities within a specific geographic area. This structure mirrors that of the Raspur Pact, ensuring operational compatibility and facilitating the potential transfer of responsibilities should circumstances require.

Each Continental Theatre Command is headquartered in the territory of its designated lead nation, with the command headquarters typically co-located with or near the National Coordination Office. This distributed command structure ensures that military planning and coordination occur close to the areas of responsibility while maintaining integration through the CATO Integrated Communications Network.

Continental Theatre Command	Lead Nation	Headquarters	Member States Present	Supreme Commander
Apollonia Command	Vegno	Cossa	Vegno  Natopia  Nouvelle Alexandrie	TBC
Eura Command	Nouvelle Alexandrie	Punta Santiago	Nouvelle Alexandrie  Oportia	TBC
Tapfer Command	Natopia	Lindstrom	Natopia	TBC
Keltia Command	Nouvelle Alexandrie	Parap	Nouvelle Alexandrie  Aerla	TBC
Corum Command	East Zimia and the Wallis Islands	Southman	East Zimia and the Wallis Islands  Oportia	TBC

Each Continental Theatre Command is responsible for the coordination of military planning and operations within its area of responsibility. Other responsibilities include maintaining readiness for collective defense operations, such as conducting joint exercises among member states' forces in different regions, developing regional contingency plans, and liaising with corresponding Raspur Pact theatre commands where applicable.

The lead nation for each command is responsible for providing the command infrastructure, hosting the theatre headquarters, and supplying the senior command staff. Other member states with forces in the region contribute personnel to the integrated command structure.

Combined Function Commands

In addition to geographic commands, CATO maintains several Combined Function Commands responsible for specialized military capabilities that operate across all theatre commands. Each Combined Function Command is headquartered in the territory of its designated lead nation, with liaison elements at the Continental Theatre Command headquarters.

Combined Function Command	Lead Nation	Headquarters	Function
Maritime Command	Natopia	Lindstrom	Coordination of naval operations; maritime domain awareness; protection of sea lines of communication
Information Warfare Command	Nouvelle Alexandrie	Cárdenas	Cybersecurity; electronic warfare; communications security; coordination with Sarbanes-Lopez CyberSecurity
Space Operations Command	Natopia	Lindstrom	Satellite communications; space domain awareness; coordination with NOVA Shield and Joint Space Research Initiative
Strategic Logistics Command	Nouvelle Alexandrie	Punta Santiago	Joint logistics coordination; prepositioning of equipment; sustainment planning
Joint Intelligence Center	Oportia	Vanie	All-source intelligence fusion; threat assessment; support to Concord Intelligence Sharing Agreement

Basic hierarchy of units

CATO has adopted a standardized unit hierarchy compatible with Raspur Pact organizational structures, facilitating interoperability between the two alliance systems. Member states maintain their national unit designations but organize forces assigned to CATO commands according to this common framework.

Term	Definition
Corps	Unit of 43,200+ personnel, formed of 3 or more divisions
Division	Unit of 14,400 personnel, formed of 2 brigades
Brigade	Unit of 7,200 personnel, formed of 6 regiments
Demi-Brigade	Unit of 3,600 personnel, formed of 3 regiments
Regiment	Unit of 1,200 personnel, formed of 10 squadrons
Demi-Regiment	Unit of 600 personnel, formed of 5 squadrons
Cohort	Unit of 360 personnel, formed of 3 squadrons (motorized infantry only)
Squadron	Unit of 120 personnel, formed of 3 troops
Troop	Unit of 40 personnel, formed of 5 sections
Section or Squad	Unit of 8 personnel, formed of 2 teams
Team	Sub-unit of 4 personnel

Numbered armies assigned to CATO commands follow a sequential numbering convention corresponding to the continent where the army headquarters has been established:

• 100-199: Armies assigned to Apollonia Command;
• 200-299: Armies assigned to Eura Command;
• 300-399: Armies assigned to Keltia Command;
• 400-499: Armies assigned to Tapfer Command;
• 500-599: Armies assigned to Corum Command.

Communications infrastructure

The alliance completed its integrated communications infrastructure in 1742 AN, six months ahead of the timeline established at the 1741 Concord Council Summit. The NAX€42 billion joint infrastructure project created a quantum-encrypted command and control system spanning all CATO territories, incorporating triple-redundant transmission paths through satellite, submarine cable, and terrestrial networks.

The system features artificial intelligence-powered translation capabilities enabling real-time multilingual communication between command structures. The quantum encryption protocols, developed jointly by Natopian and New Alexandrian research teams, provide enhanced security for alliance communications. The network can automatically reroute communications and respond to multiple simultaneous attacks without manual intervention.

Each National Coordination Office serves as a node in the communications network, ensuring that all member capitals maintain direct, secure connectivity to alliance command structures.

Operations

Exercises

CATO conducts regular joint exercises to maintain interoperability and readiness among member forces. The exercise program includes annual, biennial, and periodic exercises of varying scope and focus.

Exercise	Location	Participants	Frequency	Focus
Exercise Steadfast Unity	Rotating	All member states	Annual	Combined arms; collective defense scenarios
Exercise Concord Shield	Natopia	Natopia  Nouvelle Alexandrie	Biennial	Air defense; strategic communications

Membership

Following the Butter Cow City Summit, CATO's membership policies were revised to allow for expansion. While the original Tripartite Pact was not open for accession by other states, the new Concord Alliance framework provides mechanisms for new members to join, subject to strict criteria and approval by existing members. The process for admitting new members is overseen by the Concord Council, which evaluates applications based on the established criteria and conducts necessary diplomatic negotiations.

Membership requirements

For a state to be considered for membership in CATO, it must meet the following criteria:

1. Adhere to the Concord Alliance Treaty and its principles;
2. Accept and comply with all existing CATO agreements and protocols;
3. Receive a unanimous vote of approval from the current member nations.

Current members

As of 1752 AN, CATO comprises six member states, including the three founding nations and three expansion members:
