The eastern part of Romania in 1550 came under Habsburg rule, which caused the attack of the Ottoman army against Hungary. In 1552 two Ottoman armies crossed the border into the Hungarian Kingdom. One of them – led by Hadim Ali Pasha – started a campaign against the western and central part of the country whilst the second army – led by Kara Ahmed Pasha – attacked the fortresses in the Banat region. The siege resulted with a decisive Ottoman victory and Temesvár came under Ottoman control for 164 years.
