This is a flag created by Arthur Drakoni from Deviant Art for an alternate history China where China was ruled by Chinese Muslim rulers for a long time. Even though Muslims are still a minority in this alternate world they are thoroughly Chinese and have become integral to the Chinese identity.
I have made this Islamic China flag inspired by Toixstory’s The Grand War map.
In Tioxstory’s own words: This is the world in a universe that diverged from our own in the year 876, with the death of Huang Cho during his rebellion before he could kill one hundred thousand rich Muslims in southern China. Without their deaths, Islam continued to grow in China during the centuries, especially among the rich merchant classes. Eventually, after a brutal series of civil wars, an Islamic dynasty came to power in Hangchow, and would rule China from the late 15th century until the current year, 1894. While most of China still practices Buddhism, Confucianism, and other religions, the Islamic rulers have adapted themselves to Chinese culture and customs well enough that they are accepted as rulers of China, much like the Manchu of our own world. Muslim Chinese are a growing minority group, however, especially as many of the rich at least pay tribute to being Muslim, if only for the sake of political power.
