At the time when Iraq was admitted to membership of the League of Nations in 1932, the League Council had referred to the Mandates Commission certain petitions which had been received from the Assyrians and Kurds; but in view of the fact that the Treaty between Britain and Iraq, governing the termination of the mandate, included a draft declaration containing guarantees to cover the protection of minorities, Iraq was admitted before the Mandates Commission had prepared its Report.
