He came to Edirne for the peace treaty and he gave his sister to Bayezid and with this marriage, Ottoman – Serbian friendship was accomplished. Unfortunately, Bayezid, was defeated in the Ankara War by Timur (the Mongolian Khan). Timur slaved him and Bayezid died in seven months twelve days. His sultanate took 13 very victorious years but ended very sadly. He wore clothes of brocade with a white loose neck and his turban was coiled and wound round a gold embroidered üsküf.
