Ikhwan raids on Transjordan were a series of plunders by the Ikhwan, irregular Arab tribesmen of Najd, on Transjordan between 1922 and 1924. The repeated Wahhabi incursions from Najd into southern parts of his territory were the most serious threat to emir Abdullah's position in Transjordan. The emir was powerless to repel those raids by himself, thus the British maintained a military base, with a small air force, at Marka, close to Amman. The British military force was the primary obstacle against the Ikhwan, helping Emir Abdullah to secure his rule over Transjordan.
