Right, I wonder how much we are, globally speaking, becoming very Anglo-centric in our understanding of history, merely because we use the English language for international communication and therefore it's easier to consume histories and writings produced by Anglos.
Maybe not that much. At my British university (Imperial) the majority of the students at the very least don't look "Anglo" and don't have Anglo names.
When I started my PhD I was greeted with an email with the names of all other PhDs starting at the same year, cc'd. So I saw everyone's names (in Office 360- you can see the names attached to the email addresses) and I think there were two or three recognisably Anglosaxon names in about 80 names.
So I suspect it's more that English is used as a lingua franca for students and researchers from all over the world, than that students and researchers are predominantly native English speakers.
Myself, for example, am not a native English speaker :)
