Royal Air Force Station Hinaidi, more commonly known as RAF Hinaida, was a British Royal Air Force station near Baghdad in the Kingdom of Iraq. In Clause 1 of the "Annexure to Treaty of Alliance" section of the Anglo-Iraqi Treaty of 1930, maintaining a force at Hinaidi was indicated to be permitted for a period of "five years after the entry into force of this Treaty." This time was provided "in order to enable His Majesty the King of 'Iraq to organise the necessary forces to replace them." By April 1941, during the 1941 Iraqi coup d'état, the base had been vacated by the British and was re-named "Rashid Airfield" by the Iraqis.[1] The name was in honor of Rashid Ali, former Iraqi Prime Minister and the leader of the coup d'état. During the Anglo-Iraqi War in May 1941, the base was used by the Royal Iraqi Air Force in the fighting against the RAF.
