suleiman tried to capture vienna, the capital of the habsburg austrian empire, two times. one time in 1529 after he destroyed and captured the kingdom of hungary in the 1526 battle of mohács, and another time in 1532. both times suleiman failed. the siege of vienna became the end of the growth of the ottoman empire into europe. after these failed attempts, suleiman started to focus on growing his empire into asia and the mediterranean instead of central europe.
