In May 1532
Saadet I Giray voluntarily renounced the position of khan and left for Istanbul.
İslâm I Giray returned to Crimea and was proclaimed khan. The Ottoman Sultan did not recognize him and in the fall appointed Sahib as Crimean khan. He arrived with Turkish troops and was recognized by the Crimean nobles. İslâm, after a five-month reign, became Sahib's Kalga and was given possession of
Perekop and
Ochakiv. In the spring of 1534 İslâm revolted. He was repulsed from Crimea and fortified himself in Perekop. Saadet’s son Akhmed was made Kalga, but was killed in 1537 on Sahib’s order. Sahib’s son Emin then became Kalga. In 1537 Sahib drove İslâm out of Perekop. He fled to the
Nogais and was killed by Baki-Beg, the Karachi Beg of the Mangit clan. In terms of domestic policy, Sahib founded the new capital of
Bakhchisarai 2 km downstream from the old capital of Salachik (prior to this, the nearby cliff-fort of
Chufut-Kale and before that
Stary Krym had served as capitals). Sahib expanded the harbor of Gozlev/
Yevpatoria, giving the khanate its own port. He tried to weaken the great nobles by bringing their leaders to court and elevating the lesser nobles, and tried to sedentarize the Nogais. When Sahib went to war he was accompanied by a guard of musketeers, wagons and field artillery. The main force was tribal cavalry. In 1538 Sahib joined forces with
Suleiman the Magnificent to fight the Moldavian ruler
Petru Rareș, resulting in the Ottoman occupation of
Ochakov and the separation of the
Budjak coast from Moldavia. In 1539 Sahib marched to the Taman peninsula to punish the Circassians for their attacks on Muslims. Kansavuk, the leader of the
Zhaney tribe, bought him off with gifts to the Khan, Sultan and Turkish governor of Kaffa. A search in the mountains for the guilty parties failed. On the way back the Crimeans looted some Circassian villages. In the winter of 1539/40 Sahib and his son Emin raided Lithuania and possibly Muscovy. The campaign was successful, but the returning troops suffered much from the cold. In 1541 Sahib and Emin raided Muscovy. The runaway Prince Semyon Belsky promised to show them a ford over the
Oka River, but they were late due to quarrels between Sahib and Baki-Beg. The Russians blocked the river bank with artillery and the Crimeans went home, taking a little loot. In 1542 Sahib and Emin returned to the
North Caucasus because Kansavuk had not fulfilled his promises, including the delivery of slaves. They entered the mountains, were attacked at night, were victorious, and returned with much loot. 1544 the
Kabardian Prince Elbozady arrived in Crimea asking for help against his rebellious subjects. The Tatars marched east, defeated a night attack by the Kabardians and returned with many captives. In 1545 Astrakhan was captured and
Yamghurchi of Astrakhan was driven out. In 1546 10000 Nogais under Ali-Mirza attacked Crimea to avenge the capture of Astrakhan. The Crimeans surrounded them near Perekop and utterly defeated them by blasting them with artillery and musket fire. After the battle Sahib ordered many of the prisoners executed. ==Overthrow and death (1551)==
