Qasimid

The Qasimid State (Arabic: الدولة القاسمية), also known as the Imamate of Yemen, was a state in South Arabia which was ruled by the Imams of Yemen. It was founded by Imam al-Mansur al-Qasim in 1597, absorbed much of the Ottoman-ruled Yemen Eyalet by 1628, and then completely expelled the Ottomans from Yemen by 1636. The Qasimid State continued to exist into 18th and 19th century, but gradually fractured into separate small states. The most notable of those states was the Sultanate of Lahej; most of those states (except Lahej) were submitted by the Ottomans and incorporated into the restored Ottoman province of Yemen Eyalet in 1849.
