The Battle of Kruševac was fought on October 2, 1454 between the forces of the Serbian Despotate, allied with the Kingdom of Hungary, and the Ottoman Empire. [3] In 1454 the Ottomans launched a major invasion against Serbia, at the helm of which was the Sultan himself, Mehmed the Conqueror. Initially, Serbs led by Nikola Skobaljić scored a ...
It was the first treaty signed by Mehmed the Conqueror following the capture of Constantinople in 1453. It effectively ended Venetian aspirations to eliminate the Ottoman Empire or to conquer Constantinople on behalf of Christendom. The treaty gave the Republic of Venice freedom to trade in the Eastern Mediterranean.

Early evidence of large eruption in 1450–1460 came from a massive sulfate spike recorded in ice cores in Antarctica with dating uncertainty up to a few years. Early studies in the 1990s and 2000s incorrectly placed the date of this original sulfate spike in 1452/53 on the basis of high dating uncertainty while the Kuwae caldera in Vanuatu was assig...
The 1452/53 sulfate spike is recorded in both Greenland and Antarctica, but the sulfate signal in Greenland is significantly larger than that of Antarctica, suggesting a source volcano in the low latitudes of the Northern Hemisphere. Sulfur isotope composition of the 1452/53 sulfate indicates that the eruption emitted volcanic gases directly into t...
Kuwae was associated to the original 1452/53 sulfate event which has been re-dated to 1458 based on higher dating accuracy in 2012. The question whether Kuwae may actually be the source of 1452/53 event rather than the 1458 event is thought to be likely negative due the asymmetric distribution of sulfate in Greenland and Antarctica. The asymmetry w...
Mexican codices describe autumn frosts in 1453 that affected agriculture throughout central Mexico. According to the history of the Ming dynasty in Chinain the spring of 1453, "nonstop snow damaged wheat crops". Later that year, as the dust obscured the sunlight, "several feet of snow fell in six provinces; tens of thousands of people froze to deat...
