War of Fellow Brothers

The War of Fellow Brothers (Bai: 同胞之战) was a theatre of the Great Revolutionary Wars fought in Northern Archanta between the Bai Democratic Republic and the Socialist Alliance to Restore the Empire, in the 1930s and 40s. Starting in 1932 with the invasion of Kanglapo, it ended with the Fascists' defeat.

The 1922 coup led to the overthrow of the Middle Bai Dynasty, and the fascists, under Yu Shanliu, sought to destroy the socialists and the remnants of the monarchy through a civil war. The communist neighbours, backing the socialist faction against the fascists, led to the rise of tensions between the fascists and the pro-socialist and communist neighbours, in addition to conflicts over territorial disputes (the Bai Gulf Crisis). On 22 June 1932, the Bai Fascist Republic launched Operation Honghua, triggering the War of Fellow Brothers.

While the fascists saw early successes, including the successful occupation of Kaosha, and the elimination of the Bai Emperor, the strong opposition to fascist occupation, economic crises and the drop in support by its allies led the leader Yu to declare surrender and shortly afterwards committed suicide on 30 April 1942. Although the war was a victory for the socialists, it led to a cold war divide between the Bai socialists and its neighbours. The Bai socialists also struggled to reinstate law and order in the Empire as various warlords and generals claimed control over various areas of the empire, leading into the Warlord Era.
