Sigismund, Holy Roman Emperor
Possessions in Serbia

Threatened by Ottoman expansion, King Sigismund managed to strengthen the security of southern Hungarian borders by entering into a defensive alliance with Despot Stefan Lazarević of Serbia. In 1403, Hungarian possessions in northwestern regions of Serbia (city of Belgrade and the Banate of Macsó), were given to Despot Stefan, who pledged his allegiance to King Sigismund, remaining the king's loyal vassal until death in 1427. Stefan's successor George Branković of Serbia also pledged his allegiance to Sigismund, returning Belgrade to the king. By maintaining close relations with Serbian rulers, Sigismund succeeded in securing southern borders of his realm.
