No it wasn't. It was actually a geographical term first used in Anglo-Saxon times to differentiate the mainland from smaller bodies such as the Channel Islands. 'Great Britain' refers to England, Scotland and Wales - not, crucially, Northern Ireland - because that is specifically the mainland. The country is called the United Kingdom.
Just a bit of geopolitical history for you. Don't mind me.
I didn't know that, thanks,
I don't have an extensive political, historical an grammatical knowledge, but being called a 'pseudo-patriot' sort of makes me feel either I should dare not say anything Nationalistic or have Patriotic opinions because I happened to be of English origin.
I happen to like the idea that Great Britain was referred to that because of the grandeur of the Empire.
