The 1430s decade ran from January 1, 1430, to December 31, 1439.









  • Vlad II Dracul seizes the recently vacated throne of Wallachia, with Hungarian support.
  • The Bosnian language is first mentioned in a document.
  • Date of the Visokom papers, the last direct sources on the old town of Visoki.
  • In Ming dynasty China, the inauguration of the Zhengtong Emperor takes place.
  • In Ming dynasty China, a significant portion of the southern grain tax is commuted to payments in silver, known as the Gold Floral Silver (jinhuayin). This comes about due to officials' and military generals' increasing demands to be paid in silver instead of grain, as commercial transactions draw more silver into nationwide circulation. Some counties have trouble transporting all the required grain to meet their tax quotas, so it makes sense to pay the government in silver, a medium of exchange that is already abundant amongst landowners, through their own private commercial affairs.
  • The Florentine polymath Leon Battista Alberti begins writing the treatise On Painting, in which he argues for the importance of mathematical perspective, in the creation of three-dimensional vision on a two-dimensional plane. This follows the ideas of Masaccio, and his concepts of linear perspective and vanishing point in artwork.
  • Afonso Gonçalves Baldaia becomes the first European to explore the western coast of Africa, past the Tropic of Cancer.
  • Johannes Gutenberg begins work on the printing press.



  • Pachacuti becomes ruler of the Kingdom of Cusco and begins its expansion into the Inca Empire (Tahuantinsuyu).
  • 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.
