Gertrude Bell, describing the Sunni element in Iraq:
The Sunni element in Iraq, though small, enjoys a social and political importance incommensurate with its size. It consists mainly of great landowners, such as the Sa’dun and the houses of the Naqibs of Baghdad and Basrah, and the wealthy merchants inhabiting the towns and holding estates along the rivers. With the exception of Sa’dun, the Sunnis of the Iraq are mostly town-dwellers. Since the country has been under the Sunni government of the Turks, Shiahism has had no political status, Shiah religious bequests had not had legal recognition, nor has the Shia ecclesiastical law, which differs from that of the Sunnis, been included in the Ottoman code.
And on the Sunni-Shia relationship in Iraq:
Partly, it may be, because of the unquestioned nature of the Sunni ascendancy, there has been little jealous or bitterness between the two branches of Islam in the Iraq, and whatever changes the future may bring, it should be the first care of the rulers of the country to preserve that fortunate condition.
