Question: 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

<P0-S0> This is a list of campaigns personally led by Mehmed II or Sultan Mehmed the Conqueror (30 March 1432 – 3 May 1481) (Ottoman Turkish: محمد ثانى, Meḥmed-i s̠ānī; Turkish: II. <P0-S1>  Mehmet; also known as el-Fātiḥ, الفاتح, "the Conqueror" in Ottoman Turkish; in modern Turkish, Fatih Sultan Mehmet; also called Mahomet II in early modern Europe) was Sultan of the Ottoman Empire twice, first for a short time from 1444 to September 1446, and later from February 1451 to 1481. <P0-S2>  At the age of 21, he conquered Constantinople and brought an end to the Byzantine Empire, transforming the Ottoman state into an empire. <P0-S3>  Mehmed continued his conquests in Asia, with the Anatolian reunification, and in Europe, as far as Bosnia and Croatia. <P0-S4>  Mehmed II is regarded as a national hero in Turkey, and Istanbul's Fatih Sultan Mehmet Bridge is named after him. <SEP> <P1-S0> Mehmed II (Ottoman Turkish: محمد ثانى‎ , "Meḥmed-i sānī"; Modern Turkish: "II. <P1-S1>  Mehmet" ; 30 March 1432 – 3 May 1481), commonly known as Mehmed the Conqueror (Turkish: "Fatih Sultan Mehmet" ), was an Ottoman sultan who ruled first for a short time from August 1444 to September 1446, and later from February 1451 to May 1481. <P1-S2>  At the age of 21, he conquered Constantinople (modern-day Istanbul) and brought an end to the Eastern Roman Empire. <P1-S3>  Mehmed continued his conquests in Anatolia with its reunification and in Southeast Europe as far west as Bosnia. <P1-S4>  Mehmed is considered a hero in modern-day Turkey and parts of the wider Muslim world. <P1-S5>  Among other things, Istanbul's Fatih district, Fatih Sultan Mehmet Bridge and Fatih Mosque are named after him. <SEP> <P2-S0> Hatice Âlime (Halime) Hüma Hatun (Ottoman Turkish: هما خاتون‎ , 1410 ‒ September 1449) was the fourth wife of Ottoman Sultan Murad II and mother of Mehmed II. <P2-S1>  She was a slave girl. <P2-S2>  Nothing is known of her family background, apart from the fact that an Ottoman inscription (vakfiye) describes her as "Hātun binti Abdullah" (Daughter of Abdullah); at that time, people who converted to Islam were given the name "Abdullah" meaning "Servant of God", which is evidence of her non-Muslim origin. <P2-S3>  Her name, "hüma", means "bird of paradise", after the Persian legend. <P2-S4>  There are two theories on her origin: She was a romanian named Stella; She was Serbian, some sources saying that she was a princess from the Principality of Zeta and a relative of Đurađ II Balšić. <P2-S5>  S. Runciman and Ilber Ortayli support that she was of Slavic descent. <P2-S6>  She died in September 1449 in Bursa. <SEP> <P3-S0> 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. <P3-S1>  He was brought up in Amasya, and ascended the throne on the death of his father Mehmed I. <P3-S2>  His mother was Valide Sultan Emine Hatun (daughter of Suleyman Bey, ruler of Dulkadirids), his father's third consort. <P3-S3>  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.
