| Additional information |
The Great Han was one of several short-lived rebel kingdoms that fractured the collapsing Yuan dynasty in the 1350s and 60s. Chen Youliang proclaimed himself emperor of Han in 1360, controlling much of the middle Yangtze region, and issued the Dayi Tongbao as an assertion of imperial legitimacy against both the fading Mongol court and his rivals — including Zhu Yuanzhang, who would eventually found the Ming. Chen was killed at the Battle of Lake Poyang in 1363, one of the largest naval engagements in premodern history, ending the dynasty after roughly three years.
