The 1686 Siege of Buda Ended 145 Years of Ottoman Rule in Hungary
After a failed attempt in 1684, the Holy League returned to Buda with a massive coalition army. The resulting 1686 siege was a brutal turning point that not only expelled Ottoman forces but fundamentally reshaped the political future of Hungary under the hereditary rule of the Habsburg monarchy.
The siege of Buda, lasting from 18 June to 9 September 1686, was a pivotal military engagement of the Great Turkish War. Following the Ottoman defeat at Vienna in 1683, Emperor Leopold I sought to reclaim the Hungarian capital, which had been under Ottoman control since 1541. The first attempt in 1684 failed after 108 days, but the 1686 campaign utilized a vastly larger coalition of 65,000 to 100,000 soldiers from across Europe, including German, Hungarian, English, and Spanish forces. Opposing them were 7,000 Ottoman defenders led by Abdurrahman Abdi Arnavut Pasha.
The conflict was marked by extreme violence. During the final assault, the imperial troops, enraged by high casualties and the long, persistent resistance of the defenders, engaged in widespread slaughter. The violence targeted both the Muslim population and the Jewish community, who were viewed as Ottoman allies. Contemporary accounts, such as those from army doctor Johann Dietz, describe the brutality as exceeding that of wild beasts. While the Elector of Bavaria and the Duke of Lorraine eventually intervened to stop the massacre, thousands were killed, and the city’s mosques and synagogues were destroyed.
The fall of Buda had profound political consequences. The recapture was not achieved by a local Hungarian uprising but by the forceful intervention of the Habsburgs. This reality dictated the post-war settlement, as the Hungarian Diet at Pressburg was compelled to recognize hereditary Habsburg rule in 1687. By December 1687, the nine-year-old Joseph was crowned king, and by 1688, a commission was established to solidify a strong monarchistic government over the kingdom. Today, the event is commemorated in Budapest by a monument marking the spot where Spanish troops breached the city walls.
