Blackbirds, a large plain in Old Serbia, at the southern end of which is
Skoplje. At this battle Serbian armies from all the Serb lands, including
Bosnia, joined together in defence of their country for the last time. The
issue of the battle was for some time in doubt, but was decided by the
treachery and flight at the critical moment of one of the Serb leaders,
Vuk Brankovi['c], son-in-law of Prince Lazar, with a large number of
troops. Another dramatic incident was the murder of Sultan Murad in his
tent by another Serbian leader, Milo[)s] Obili['c], who, accused of
treachery by his own countrymen, vowed he would prove his good faith, went
over to the Turks and, pretending to be a traitor, gained admission to the
Sultan's presence and proved his patriotism by killing him. The momentary
dismay was put an end to by the energetic conduct of Bayezid, son of
Murad, who rallied the Turkish troops and ultimately inflicted total
defeat on the Serbians. From the effects of this battle Serbia never
recovered; Prince Lazar was captured and executed; his wife, Princess
Milica, had to give her daughter to Bayezid in marriage, whose son thus
ultimately claimed possession of Serbia by right of inheritance. Princess
Milica and her son Stephen continued to live at Kru[)s]evac, but Serbia
was already a tributary of Turkey. In the north, Hungary profited by the
course of events and occupied Belgrade and all northern Serbia, but in
1396 the Turks defeated the Magyars severely at the battle of Nikopolis,
on the Danube, making the Serbs under Stephen fight on the Turkish side.
Stephen also had to help Sultan Bajazet against the Tartars, and fought at
the battle of Angora, in 1402, when Tamerlane captured Bayezid.

After Stephen returned to Serbia he made an alliance with Hungary, which
gave him back Belgrade and northern Serbia; it was at this time (1403)
that Belgrade first became the capital, the political centre having in the
course of fifty years moved from the Vardar to the Danube. The disorders
which followed the defeat of Bayezid gave some respite to the Serbs, but
