Date unknown[edit]

  • Pachacuti becomes ruler of the Kingdom of Cusco and begins its expansion into the Inca Empire (Tahuantinsuyu).[3]
  • 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 illegal mining of silver is now an offense punishable by death; although it becomes a dangerous affair, the high demand for silver also makes it very lucrative, and so many chose to defy the government and continue to mine.
  • The Sukhothai Kingdom merges with the Ayutthaya Kingdom.
