Fakhr al-Dīn II (born c. 1572—died 1635, Constantinople [now Istanbul, Turkey]) was a Lebanese ruler (1593–1633) who for the first time united the Druze and Maronite districts of the Lebanon Mountains under his personal rule; he is frequently regarded as the father of modern Lebanon.
With the death of Fakhr al-Dīn’s father, Korkmaz, in 1585, a civil war broke out between the two predominant religious–political factions in the region, the Qaysīs and the Yamanīs. After Fakhr al-Dīn and his Qaysī faction emerged victorious in 1591, he became determined to unite the perpetually feuding Maronite and Druze districts. Although he himself was of the Druze religion, he had the support of the Christian Maronites of what is now northern Lebanon, who resented their tyrannical ruler Yūsuf Sayfā. Fakhr al-Dīn then became locked in a seven-year struggle for supremacy, a struggle that was complicated by the fact that the Ottomans, the nominal rulers, allied themselves first with Fakhr al-Dīn and then with Yūsuf Sayfā. Finally, with the defeat of Yūsuf Sayfā (1607), the Ottomans recognized Fakhr al-Dīn’s authority.
Because Fakhr al-Dīn was still uncertain of Ottoman support, however, he allied Lebanon with Tuscany in 1608. The increasing ties with the Tuscans aroused the suspicion of the Ottomans, and they forced Fakhr al-Dīn into exile (1614–18). After his return he made peace with his old rival Yūsuf Sayfā, cementing it with a marriage alliance.
Fakhr al-Dīn then continued his conquests, and by 1631 he dominated most of Syria, Lebanon, and Palestine. The Ottomans, wary of his growing power, sent troops against him and defeated him in 1633. Fakhr al-Dīn fled to the Lebanon Mountains, where he was captured (1634). He was executed in Constantinople. Though Fakhr al-Dīn’s domains were fragmented after his death, the union of the Druze and Maronite districts survived.
