Arab scholars up to the 1960s have also refered to the body of water as per its correct name "Kahleej-ol-Faris" (Persian Gulf) - see George Hourani (Arab Seafaring).

The "Arabian Gulf" actually referred to the present-day Red Sea in antiquity (i.e. Herodotus). The invention of "Arabian Gulf" with respect to its historically incorrect reference to the Persian Gulf was initiated by Sir Charles Belgrave (1920s) and Roderic Owen (1950s).

Note that the CBC has removed all references to "Arabian Gulf" and now correctly refers to the body of water as The Persian Gulf. This is the result of a contact made to Russ Germain (Broadcast Language advisor, CBC Radio Canada) almost 3 years ago. Mr. Germain recommended that all references to "Arabian Gulf" be removed from CBC broadcasts in favor of the legal and correct term, Persian Gulf
