Saudi–Rashidi War of 1903–1907, also referred as the First Saudi–Rashidi War or the Battles over Qasim, was a conflict between Saudi loyalist forces of the newborn Emirate of Riyadh and the Emirate of Ha'il (Jabal Shammar), supported by the Rashidis. The pro-Ottoman Rashidis were supported by 8 battalions of Ottoman infantry. The majority of the war was fought out in a series of sporadic battles, which ended with a Saudi takeover of the al-Qassim region following their decisive victory at Qassim on April 13, 1906,[2] though additional engagements followed in 1907.
