Empire of Zhenia

The Empire of Zhenia (Zhenian: 대동진제국, literally translated as "Empire of Great Zhenia"), was a historical and  that existed as the direct predecessor to modern-day Zhenia, from June 4, 1438 AC until the Declaration of Union following the December Revolution in 1499 AC. Its history spanning over 61 years, it saw the reign of four emperors during its rule, starting from Emperor Seongjo and ending with Emperor Gojong.

It was founded on June 4, 1438 AC, shortly after the end of the Wars of Zhenian Unification, when the pre-existing Confederation of Zhenia was reorganized into an empire centered around Shindan via the Declaration of Zhenian Unification, thus introducing the title of Emperor of Zhenia to Emperor Seongjo, then-Emperor of Shindan and Khagan of the Yemeg and Balakhaat People. Daedo was selected as the new imperial capital, although the Government of Shindan would assume complete control over foreign and military affairs from Sanggyeong until it too completely relocated to Daedo in 1451. While the emperor remained the head of state, the Prime Minister of Shindan also became the empire's.

Emperor Gojong (1489-1499)
The reign of Emperor Gojong from 1489 to 1499 AC saw the progression of the empire into a full republic as a result of the December Revolution and the Declaration of Union, as well as the continuity of modernization and industrialization in mainland Zhenia.

Legacy
Under the leadership of Emperor Seongjo and the Confederation, the unified Zhenian state in the modern sense of the word had finally been achieved, despite it was primary led by Shindan and the Golden Arc region. Imperial rule under the Empire also laid out several characteristics defining modern Zhenia, including freedom of the presses and protest, a governmental system centered around the Parliament, a social system completely devoid of the traditional caste system and a standardized education system proliferated nationwide.
