Flag of Jeuna

The revolution of 1855 introduced the reverse-pennant of the Republicans in their iconic Republican Blue. This flag served as the war flag and naval ensign for all revolutionary forces, although its design was not standardised until 1914, when Chen Falong made for the first time a construction sheet for the flag. Until the Tsing Emperor's abdication in 1855, the display or even ownership of the flag, in part or in whole, was punishable by death.

During the Civil War of 1938-43, this flag was used by the Republican forces.
