A Part of the Hamdan family had been banished from Mount Lebanon following the battle of Ain Dara in 1711. This battle was fought against two Druze factions : the Yemeni and the Kaysi. The Kaysi were represented by the Jumblat and Arslan families and the Yemeni by the Hamdan and Al-Atrash families. And the other part stayed in Lebanon, and ruled Al Mnasef region, which contained many villages, and made Deir Koushe as their home village. and then moved to Bater, Chouf District; after Sheikh Bashir Jumblat, their relative, asked them to go and stay there, by an order from Prince Bashir Shehab, because of their daily fights/wars with their neighbors Al Nakad (which they wanted to be the leaders in Mnasef). The Hamdan Family used to be and are still from the wealthiest Druze Sheikhs (Lords) in Lebanon and Al-Sham.
