The Maan family, under orders from the governor of Damascus, came to Lebanon in 1120 to defend it against the invading Crusaders. They settled on the southwestern slopes of the Lebanon Mountains and soon adopted the Druze religion. Their authority began to rise with Fakhr ad Din I, who was permitted by Ottoman authorities to organize his own army, and reached its peak with Fakhr ad Din II (1570-1635).
Although Fakhr ad Din II’s aspirations toward complete independence for Lebanon ended tragically, he greatly enhanced Lebanon’s military and economic development. Noted for religious tolerance and suspected of being a Christian, Fakhr ad Din attempted to merge the country’s different religious groups into one Lebanese community. In an effort to attain complete independence for Lebanon, he concluded a secret agreement with Ferdinand I, duke of Tuscany in Italy, the two parties pledging to support each other against the Ottomans. Informed of this agreement, the Ottoman ruler in Constantinople reacted violently and ordered Ahmad al Hafiz, governor of Damascus, to attack Fakhr ad  Din. Realizing his inability to cope with the regular army of Al Hafiz, the Lebanese ruler went to Tuscany in exile in 1613. He returned to Lebanon in 1618, after his good friend Muhammad Pasha became governor of Damascus.

Following his return from Tuscany, Fakhr ad  Din, realizing the need for a strong and disciplined armed force, channeled his financial resources into building a regular army. This army proved itself in 1623, when Mustafa Pasha, the new governor of Damascus, underestimating the capabilities of the Lebanese army, engaged it in battle and was decisively defeated at Anjar in the Biqa Valley. Impressed by the victory of the Lebanese ruler, the sultan of Constantinople gave him the title of Sultan al Barr (Sultan of the Mountain).

In addition to building up the army, Fakhr ad Din, who became acquainted with Italian culture during his stay in Tuscany, initiated measures to modernize the country. After forming close ties with the dukes of Tuscany and Florence and establishing diplomatic relations with them, he brought in architects, irrigation engineers, and agricultural experts from Italy in an effort to promote prosperity in the country. He also strengthened Lebanon’s strategic position by expanding its territory, building forts as far away as Palmyra in Syria, and gaining control of Palestine. Finally, the Ottoman sultan Murad IV of Constantinople, wanting to thwart Lebanon’s progress toward complete independence, ordered Kutshuk, then governor of Damascus, to attack the Lebanese ruler. This time Fakhr ad Din was defeated, and he was executed in Constantinople in 1635. No significant Maan rulers succeeded Fakhr ad Din II.
