Following the Kuwait–Najd War in 1919–20, Ibn Saud imposed a trade blockade against Kuwait from the years 1923 until 1937. The goal of the Saudi economic and military attacks on Kuwait was to annex as much of Kuwait's territory as possible. At the Uqair conference in 1922, the boundaries of Kuwait and Najd were set; as a result of British interference, Kuwait had no representative at the Uqair conference. After the Uqair conference, Kuwait was still subjected to a Saudi economic blockade and intermittent Saudi raiding.
