Biography
European contemporaries called him "the Magnificent"; Ottoman tradition remembers him as Kanuni, "the Lawgiver." Süleyman I, born in 1494 in Trabzon, where his father Selim I was then provincial governor, succeeded to the Ottoman throne without contest in 1520, his rivals having been eliminated in Selim's brief and expansionist reign. His own reign of forty-six years, the longest of any Ottoman sultan, marked the empire's apogee in territory, revenue, and prestige.
His early campaigns struck west. Belgrade fell in 1521 and Rhodes, seat of the Knights Hospitaller, in 1522. At Mohács in August 1526 his army destroyed the Hungarian royal host, King Louis II dying in the rout, and the ensuing struggle over Hungary's crown drew the Ottomans into a long contest with the Habsburgs. Süleyman besieged Vienna in 1529 without success, withdrew before winter, and campaigned again in 1532; central Hungary was eventually placed under direct Ottoman rule. In the east he fought three campaigns against Safavid Iran, taking Baghdad in 1534, and the peace of Amasya in 1555 fixed the frontier for a generation. Ottoman fleets under Hayreddin Barbarossa dominated much of the Mediterranean, defeating the Holy League at Preveza in 1538.
The sobriquet Kanuni reflects the systematizing of dynastic law during his reign: the kanun, statute law issued by the sultan, was harmonized with Islamic jurisprudence and consolidated into codes regulating taxation, land tenure, and criminal penalties. The administration was served by able grand viziers, among them Ibrahim Pasha, executed in 1536, and the long-serving Sokollu Mehmed. The chief architect Sinan built the Süleymaniye mosque complex in Istanbul, and the sultan himself wrote accomplished poetry under the name Muhibbi.
His household departed from precedent. Hürrem Sultan, a concubine of Ruthenian origin, became his legal wife — an almost unparalleled step — and her influence coincided with bitter succession politics: Süleyman ordered the execution of his eldest son Mustafa in 1553, and another son, Bayezid, was put to death in 1561 after rebelling, leaving Selim as heir. Süleyman died in September 1566 in his tent during the siege of Szigetvár in Hungary, his death concealed by the grand vizier until the fortress fell. He was succeeded by Selim II, and later Ottoman writers looked back on his reign as a standard against which decline was measured.

Events
On 29 August 1526 the Ottoman army under Süleyman I destroyed the army of the Kingdom of Hungary on the plain of Mohács, near the Danube in the country's south. Süleyman had opened the road in 1521 by taking Belgrade, the key fortress of Hungary's southern defenses, and marched north in 1526 with a large, artillery-rich force. The young king Louis II, who ruled both Hungary and Bohemia, met him with an army of roughly 25,000, assembled hastily and without the substantial contingents of Transylvania under John Zápolya and of Croatia, which had not arrived. The battle lasted only a few hours. Hungarian heavy cavalry charges achieved initial momentum but broke against the Ottoman center, where chained guns and janissary volleys shattered the attack, and the army disintegrated. Most of the Hungarian high command, including both archbishops and a large part of the episcopate and baronage, died on the field or in the rout. Louis II drowned in a swollen stream during the flight, leaving no legitimate heir. Süleyman occupied and burned Buda but withdrew that autumn without garrisoning central Hungary. The succession crisis proved as consequential as the battle. By treaties of 1515 between the Habsburgs and the Jagiellonians, and through his marriage to Louis's sister Anna, Ferdinand I of Habsburg, brother of the emperor Charles V, claimed the vacant crowns. He was elected king of Bohemia in October 1526, while in Hungary rival diets elected both Ferdinand and John Zápolya, beginning a civil war that ended with the country partitioned among Habsburg "Royal Hungary," the Ottoman-held center after 1541, and an Ottoman-vassal principality in Transylvania. The Habsburg acquisition of the Bohemian and Hungarian crowns in 1526 assembled the Danubian composite monarchy that the dynasty would rule until 1918.
