Hmm... I never thought there were some conflicts in Ireland.
Look, Hafsa! There's a documentary about the start of Ireland's conflict.
It starts off with the settling off Scottish and English settler from Britain in the area know as Ulster, making it predominantly Protestant compared to the Catholic Ireland.
The North (where Protestant majority was) flourished with industry and its standard of living increased. The South (with majority of Catholics), however, suffered from unequal distribution of land and resources.
Conflict broke out over the issue of home rule as Catholics wanted complete independence, while Protestants still wanted to be part of Britain. So in 1920, Britain passed act that separated Ireland into 2 separate units. This was accepted by the Protestants and rejected by the Catholics.
The nationalist IRA fought in guerrilla warfare with British forces until a treaty was signed in 1921 for the formation of the Irish Free State (an independent country) and Northern Ireland (which stayed with Great Britain)
However, after that treaty, there were still cases of violence between Catholics and Protestants.
Yeah, but there were some small steps of peace talks along with those acts. So there is still a chance.
