Qizilbash forces under the command of Tahmasp I raid and destroy the cave monastery of Vardzia in Georgia.
In Henan province, China, during the Ming dynasty, a severe frost in the spring destroys the winter wheat crop. Torrential rains in mid summer cause massive flooding of farmland and villages (by some accounts submerged in a metre of water). In the fall, a large tornado demolishes houses and flattens much of the buckwheat in the fields. Famine victims either flee, starve, or resort to cannibalism. This follows a series of natural disasters in Henan in the years 1528, 1531, 1539, and 1545.
In Slovakia, Guta (modern-day Kolárovo) receives town status.
