Princess Milica Hrebeljanović née Nemanjić (Serbian: Милица Немањић Хребељановић · ca.

1335 – November 11, 1405) also known as Empress (Tsaritsa) Milica, was a royal consort of Serbia by marriage to Prince Lazar, who fell in the Battle of Kosovo.

After her husband's death, she took the role as queen regent of Serbia from 1389 to 1393, until her son, despot Stefan Lazarević came of age.

Almost immediately in her reign, in November 1389, she was attacked by the Hungarians under Sigismund, who hoped to take advantage of Serbia's weakness after the Battle of Kosovo.

[3] Vuk Branković, one of the leaders led by Prince Lazar in the Battle of Kosovo, became an issue for Milica's reign.

As a result, the queen regent found herself caught between two ambitious enemies, the Hungarians and Branković, who were now negotiating together and on the verge of forging an alliance.

Therefore, it has made scholars to believe it might have influenced the early sources about Battle of Kosovo, in which Branković is accused of alleged treachery against Prince Lazar by having secret negotiations with Sultan Murad.
