The Sultan who was obviously familiar with the beauty of Kera Tamara and the fact that she was a widow demanded her to become his wife as a guarantee for the peace between the two counties.

On that occasion an anonymous Bulgarian chronicle from the 15th century records: ...And on the throne came Shishman, son of Alexander.

Amorat [Murad] sent to him men to ask for his sister, but he did not want to give his sister, Tsarina Kera Tamara...[2]However, in 1378 when his attempts to stop the Turks failed, Ivan Shishman reluctantly sent Kera Tamara in the harem of the Sultan in the Ottoman capital Bursa.

And she, when she arrived there, kept her True faith, freed her people, lived well and pious and died in peace, may her memory live forever...[3]The grave of Kera Tamara remains today in Bursa in the family tomb of the Ottoman dynasty next to the grave of Murad I and the visitor know it as the place of "the Bulgarian Empress Maria".
