The siege of Van occurred in 1548 when Suleiman the Magnificent attacked Iran in his second campaign of the Ottoman-Safavid War (1532–1555).
The city of Van, which has long been strategic in Eastern Anatolia, was surrounded, put under siege, and bombarded. On this campaign, Suleiman was accompanied by the French ambassador Gabriel de Luetz, since France wanted to maintain a good relation with the Ottoman Empire. Gabriel de Luetz was able to give decisive military advice to Suleiman, as when he advised on artillery placement during the siege.[2]
