Page "Bayezid I" Paragraph 2

Bayezid ascended to the throne following the death of his father Murad I, who was killed by Serbian knight Miloš Obilić during ( June 15 ), or immediately after ( June 16 ), the Battle of Kosovo in 1389, by which Serbia became a vassal of the Ottoman Empire.

Immediately after obtaining the throne, he had his younger brother strangled to avoid a plot.

In 1390, Bayezid took as a wife Princess Olivera Despina, the daughter of Prince Lazar of Serbia, who also lost his life in Kosovo.

Bayezid recognized Stefan Lazarević, the son of Lazar, as the new Serbian leader ( later despot ), with considerable autonomy.
