In 1318, there was an open revolt of Albanian nobles against the rule of Stefan Milutin, which is sometimes credited to be incited by Prince Philip I of Taranto and Pope John XXII in order to weak Stefan Milutin's rule. Milutin has suppressed rebels without much difficulty. In 1319, Charles I of Hungary regained control over Belgrade and the region of Mačva while Milutin held control in Braničevo. In the year 1314 Milutin's son Stefan Dečanski rebelled against his father, but was captured, blinded and sent to exile in Constantinople. For the rest of Milutin's reign his youngest son Stefan Constantine was considered as heir to the throne, but in the spring of 1321 Stefan Dečanski returned to Serbia and was pardoned by his father.
