Zhenian First Republic

The Zhenian First Republic (Zhenian: 진화민국 제1공화국, pronounced Jinhwa-minguk Jaeil-gonghwaguk), alternately referred to as the First Zhenian Republic or simply the First Republic (Zhenian: 제1공화국, pronounced Jaeil-gonghwaguk) within Zhenia, was a that existed in modern-day Zhenia and northern Niunkuet. It refers to the system of government adopted from December 8, 1499, after the Declaration of Union which followed the December Revolution, to April 3, 1538, when Zhenia surrendered and thus ended the Second Great War.

Having emerged as a direct outcome of the December Revolution, the Declaration of Union gave way to the 1501 Constitution of Zhenia, which formally defined the composition of the First Republic. While the Chancellor was made the head of state instead of the now-gone emperor, the Republic retained both houses of the Parliament from imperial Zhenia to form the government's legislative branch. The early years of the Republic were characterized by centralized rule of republican leaders and continued industrialization of mainland Zhenia.

The First Republic succeeded the One Continent, One Suzerain policy through the Amasar Ren Doctrine in 1501, which effectively assumed the new republic as the "suzerain" of the east, in the place of the old Empire. Its geopolitical position as the suzerain of the east was reassured in its involvement of the First Great War and the subsequent establishment of the Daedo Treaty Organization.
