I think the history and geography we studied when I was in school centred mostly around Ireland, it's various invasions by the English and Vikings, the celtic origins of the country, and the development of the current political situation. I guess the focus on learning about all things Irish must be partly because we are only a budding Republic (being established since the early 1900's only) compared to long-established autonomous countries like England. The reason for this may have been to reinforce our sense of identity as a nation etc etc.
However we also studied a little about the other countries who were members of the European Union (remember it was a new-fangled notion when I was in school).
I don't remember ever studying anything at all about the Americas, Canada, Aisia, Africa, Australia political/geographical or historical.
