Territorial evolution of the Ottoman Empire
Suleiman I ( "Süleymān", ; almost always "Kanuni Sultan Süleyman") (6 November 1494  – 5/6/7 September 1566), was the tenth and longest-reigning Sultan of the Ottoman Empire, from 1520 to his death in 1566. Suleiman became a prominent monarch of 16th century Europe. Suleiman personally led Ottoman armies to conquer the Christian strongholds of Belgrade, Rhodes, and most of Hungary. In 1541 he annexed central Hungary while Transylvania became an Ottoman vassal. However rest of the Kingdom of Hungary including western and northern (Upper) Hungary and Croatia still were Habsburgs possessions. Suleiman also conquered Iraq in his conflict with the Safavid dynasty. Under his rule, the Ottoman fleet dominated the seas from the Mediterranean to the Red Sea and the Persian Gulf.
Heraclius I of Kakheti
In 1675, Archil conflicted with the shah's government, abandoned Kakheti and defected to the Ottoman Empire. Prince Nicholas capitalized on the ensuing turmoil, returned for a second time and was proclaimed as King of Kakheti Heraclius (Erekle) I. Earlier, in 1666, shah Suleiman I had succeeded Abbas II on the Iranian Safavid throne. In 1674, Suleiman I asked him to decisively end his stay in Russia, ordered him to Isfahan and promised to confirm him as king if Heraclius apostatized to Islam. The king refused to become Muslim and the shah's subject, citing the oath of allegiance given by his ancestor, Alexander II of Kakheti (r. 1574–1605), to Feodor I of Russia. Hence, he was deprived of the crown, being allowed, however, to settle to Isfahan. Kakheti was subsequently under direct Safavid rule.
