The flag for one of my alternate history projects. Here, we have the flag for the Republic of China.
EDIT: Smoothed it out a bit
China had long been suffering issues in trying to maintain control over its areas, especially in parts like Xinjiang regarding its Uyghur subjects. The rough decades that came after dissolving the Qing dynasty resulted in warlords crossing over and causing problems, all while Mongolia would free itself and try to reclaim its lost lands and China dealing with various mishaps.
Then came the Pacific War. Formerly the Second Sino-Japanese War, the young Republic fought against th imperialistic island as well as their warlrod collaberators. Mongolia provided limited assistance, as the nation itself was torn between those with loyal sentiments to China or those who wished to ally with Japan to better reclaim lost lands. However, Mongolia formerly sided with China when Russia sided with them. China endured several problems and the loss of several leaders, but help would come when the sleeping giant known as the US came in and even later Mexico.
The Pacific War would end, but not without toll. Xinjiang was in disarray, currently under the control of a warlord/politician who had allied with Japan and used said alliance to ally themselves with the British, who came in to parlay on behalf of the defeated Japanese (partially out of sentiment and partially to beat Germany to the punch). The deals and the following Kyoto Trials saw soem success, but China still needed hope.
That hope came through a long-hiding third force appeared to take the rule of China. They were the Chinese Democratic League, a group of various leftist political parties and organizations who managed to secure American and Russian assistance in uniting China and defeating the warlords.
In exchange, Mongolia and Tibet would be recognized as independent and China losing all claims on both of them, though Mongolia would also surrender any claims to "Inner Mongolia," a decision made due to the differing lifestyles and influences of the regions. Furthermore, due to deals with the British/Japanese, China would recognize the new Khanate of Jegunyar. However, Muslimc Chinese loyalists would follow into China and China would assist Russia in bringing the Oirat Kalmyks into Jegunyar.
Despite the hardships, China would overcome them and grow, becoming a mighty great power and having a great deal of influence over in the Pacific. They have reconciled with Russia and have bonded closely with the Americas.
The flag is a combination of two flags, the Fujian Peoples' Government/Chinese Peasants' and Workers' Democratic Party flag (the party elected into power in China's parliament during its first election) and the Kuomintang's flag. It represents the endless blue sky, the fortunate boundless red earth and the golden sun with the 12 rayes representing progress and the hours of the day, along with a golden new dawn for the powerful land.
