ماتياس كورفينوس
The siege of Vienna was a decisive siege in 1485 of the Austrian–Hungarian War. It was a consequence of the ongoing conflict between Frederick III and Matthias Corvinus. The fall of Vienna meant that it merged with Hungary from 1485 to 1490. Matthias Corvinus also moved his royal court to the newly occupied city. Vienna became for more than a decade the capital of Hungary.
