- Significance
From late September to mid-October 1529 Suleiman the Magnificent besieged Vienna, the Habsburg capital, with an army of over 100,000. The roughly 21,000 defenders under Niklas Graf Salm held the city behind hastily strengthened walls.
Suleiman's campaign had been hampered by an exceptionally wet season that bogged down his heavy siege artillery on the long march from the Balkans, leaving him without the firepower to breach the defences. After several failed assaults and with winter approaching, the Ottomans withdrew on 15 October. The repulse marked the furthest sustained Ottoman thrust into Western Europe and the limit of Suleiman's advance up the Danube. It opened roughly 150 years of tense Habsburg-Ottoman rivalry along the Hungarian frontier, punctuated by raids and counter-raids, that would culminate in the far larger second siege of Vienna in 1683.
