İslâm I Giray  İslâm I Giray (reigned 1532, lived ?–1537) was for five months Khan of the Crimean Khanate. He was preceded and followed his uncles Saadet I Girai (1524–1532) and Sahib I Giray (1532–1551). His father was Mehmed I Giray (1515–1523). Islam spent most of his life (1524–1537) trying to take the throne from his uncles. He was once Khan and twice Kalga or designated heir and co-ruler. He revolted three times, twice almost captured the khanship and once partitioned the Khanate between himself and his uncle. When not in Crimea he lived with the Nogai nomads. In 1523 his over-ambitious father, Mehmed I Girai was killed by the Nogais at Astrakhan. The Nogais then invaded Crimea and withdrew with their loot. During the raid Islam was captured. The khanship passed to Mehmed’s oldest surviving son Ğazı I Giray (1523–24), but the nobles and Turks soon replaced him with Mehmed’s brother Saadet I Girai. Islam was released from captivity and in 1524 he and three other Gerais raided Lithuania. In October, while returning with their loot, they were defeated by a Cossack flotilla while crossing the Dnieper. First revolt 1524–1526: In 1524 Islam revolted against his uncle. Either before or after declaring himself, Saadat ordered him killed. Warned by friends he fled to the Nogais. Many Mirzas took his side. Near Perekop he captured Saadat’s mother Mahmut-Sultan and her servants. He entered the Peninsula with a large army, took the capital of Kyrkor and declared himself khan. Saadet fled to the Turkish garrison at Perekop, which Islam besieged in November. Many Mirzas changed sides and in January 1525 Islam fled to the steppes. In the spring of 1525 he returned with a new army and drove Saadet from the capital. He also defeated a Turkish force from Kaffa. In autumn several great nobles changed sides and Islam fled to the steppes. In early 1526 he again appeared before Perekop. This time the factions compromised. Islam recognized Saadet as khan while he became Kalga.
