The trouble years and the time of the partition and Civil War is a dark spot in Irish history. Northern Ireland, which is often falsely referred to as Ulster, has been part of the United Kingdom since 1922, while the southern part of the country through long debates and fightings has gained independence and is now the Republic of Ireland. The basic conflict between England and Ireland, at the same time, has a very long history, and reaches back to the Middle Ages. [...] But each and every story is different. In the following essay, my main goal is to try to explore what could have led to the partition and more importantly why the Irish started to fight against their own blood, against each other.
