* At 95 years of age, [[Nang Keo Phimpha]] becomes queen of [[Lan Xang]] for a few months before being deposed and killed.
* Just two years after the [[Ming dynasty]] court of [[China]] allowed landowners paying the grain tax to pay their tax in [[silver]] instead, the Ming court now decides to close all silver mines and prohibit all private silver mining in [[Zhejiang]] and [[Fujian]] provinces. This is a concerted effort to halt the increase of silver circulating into the market.

* The [[Sukhothai Kingdom]] merges with the [[Ayutthaya Kingdom]].</onlyinclude>
