Whatis the name of this Ottoman sultan who ruled from August 1444-September 1446 that brought an end to the Eastern Roman Empire and was the son of Murad II
Murad II Murad II's reign was marked by the long war he fought against the Christian feudal lords of the Balkans and the Turkish beyliks in Anatolia, a conflict that lasted 25 years. He was brought up in Amasya, and ascended the throne on the death of his father Mehmed I. His mother was Valide Sultan Emine Hatun (daughter of Suleyman Bey, ruler of Dulkadirids), his father's third consort. Their marriage served as an alliance between the Ottomans and this buffer state, and produced a son, Mehmed II, who would go on to successfully conquer the Byzantine Empire's capital, Constantinople, in 1453.
