Moreover, I have changed some dynamic names to more accurately reflect historical counterparts (i.e. the "British Mandate of Arabia" has been changed to "Aden Protectorate" to more accurately reflect real British control over the Arabian peninsula as it existed in history).
"British Mandate" was better imo, as it shows the indirect control over much of the Middle East Britain gained with the League of Nations mandate. Aden was a small province, while the Mandate spanned from British Egypt to Persia.
