Battle of Ankara
In the Battle of Ankara on 20 July 1402, Olivera and Bayezid were captured by Timur. Olivera was widowed in 1403. A Ragusan chronicler Mavro Orbini wrote in the "Kingdom of the Slavs" (1601) that she died in captivity two days after Bayezid's death, which turned out to be incorrect. Serbian soldier and memoirist Konstantin Mihailović noted that Timur felt sorry for the Bayezid's death and released his delegation, including his wife.
