Devlet I Giray (1512–1577, r. 1551–1577, ; , ‎) was a Crimean Khan. His long and eventful reign saw many highly significant historical events: the fall of Kazan to Russia in 1552, the fall of the Astrakhan Khanate to Russia in 1556, the burning of Moscow at the hands of the Crimean Tatars in 1571 and the defeat of the Crimeans near Moscow in 1572. During Devlet's reign there were a number of Cossack raids on Crimea. Early life and enthronement Devlet was the son of Mubarak, and grandson of Meñli I Giray (1478–1515). From Mengli's death until Devlet's accession the throne was held by Mubarak's brothers and their sons, so Devlet was from a collateral branch. Mubarak served Sultan Selim I the Grim and died fighting in Egypt in 1516–17. In 1530 Devlet became Kalga to his uncle Saadet I Giray (1524–1532). When Saadet abdicated in 1532 he was imprisoned and then followed his uncle to Istanbul. Girays in the Turkish service were potential Crimean khans. In 1551 Sahib I Giray refused a Turkish order to fight in Persia. Devlet was sent to replace him. The Crimean army went over to Devlet, Sahib was captured and killed and by Devlet's order Sahib's children and grandchildren were also killed. Reign Losing Kazan Anti-Russian and pro-independent rulers of Kazan were from the Crimean Giray dynasty (these are: Sahib I Giray, Safa Giray of Kazan and Ötemish Giray). In 1551 they were replaced by the pro-Russian Shahgoli with the support of Russia, but soon the Kazanians replaced Shahgoli. Learning that the pro-Russian Shahghali had been driven out of Kazan, in March 1552 Ivan decided on a major campaign against that Khanate. Learning of this, Devlet decided to attack Muscovy while the army was away, which would give him an easy victory and also protect Kazan. Nearing Ryazan he learned that Ivan was waiting for him at Kolomna. He planned to retreat, but his men did not want to go home without loot. He besieged Tula on 21 June, but two days an advancing Russian army and a sortie by the garrison drove the Tatars away and captured the wagons and all the Turkish artillery. In October of that year Russia conquered the Khanate of Kazan. Losing Astrakhan After the fall of Kazan Yamghurchi of Astrakhan broke with Russia and allied with Crimea. Devlet sent 13 cannon but no soldiers. In the spring
