There is a tendency among French-Iranians to categorize themselves as "Persian" rather than "Iranian", mainly to dissociate themselves from the Islamic regime of Iran which is in charge since 1979 Revolution and the negativity associated with it, and also to distinguish themselves as being of Persian ethnicity, which comprise about 65% of Iran's population. While the majority of British-Iranians come from Persian backgrounds, there is a significant number of non-Persian Iranians such as Azerbaijanis and Kurds within the British-Iranian community, leading some scholars to believe that the label "Iranian" is more inclusive, since the label "Persian" excludes non-Persian minorities. The "Collins English Dictionary" uses a variety of similar and overlapping definitions for the terms "Persian" and "Iranian".
