After the relief of the Habsburg capital in the Battle of Vienna of 1683, Austria enjoyed great success and by 1688 Belgrade and most of the Pannonian Plain was occupied by Habsburgs. But as the war with the French demanded more troops, and the new grand vizier reorganized and reinvigorated the Ottoman Army, the success ended. Belgrade was recaptured by the Ottomans in 1690 and the following year’s campaign was relatively indecisive. The Austrians would be led by Eugene of Savoy in his first independent command; it was to be the first of a series of spectacular campaigns for the Prince.
