Shirerithian rule in Batavia
The period of Shirerithian rule in the Batavian lands began with the dramatic westwards expansion of Elwynn in 1640, during the period of Froyalanish dominion over the Imperial Republic, and the establishment of the Confederacy of Puritanian States under Imperial protection in 1642. After the Auspicious Occasion of 1651 and the subsequent partition of Elwynn, an Imperial Dominion (a territory under the direct rule of the Imperial Government) was established. The proximity of Jingdaoese enclaves around King's Worth and the Regent Isles to the new Imperial frontier resulted in Batavia becoming the scene of some of the most bitterly fought engagements of the War of Lost Brothers (1653–1657). The war and its aftermath led to a wave of Batavian migration (Voortrekkers) into the ungoverned territories (colloquially known as "The Green") of Inner Benacia, resulting in the establishment of Kasterburg and Transbatavia, as well as ethnic conflicts with the Siyacha and a certain level of entanglement in fraught geopolitical and ideological rivalry of Shireroth and Kalgachia. The experiences of the Voortrekkers, particularly after their violent expulsion from Nackholm by Imperial Forces resulted in the Batavian national reawakening and the attempted resurrection of a united Batavian polity in the 1660s AN.
Shirerithian rule over Batavia resumed in 1711 AN with the Treaty of Raynor's Keep, now also including former Jingdaoese-occupied 's Koningenwaarde, Transbatavia and Batavia's oversea territories.
