So the conflict is cultural, social and historical rather than religious. The IRA (the Irish Republican Army) is a Catholic paramilitary organization whose goal is to force the British out of Northern Ireland and to be reunited with the Republic of Ireland.
This organization has existed since 1919 and is said to be responsible for the deaths of more than 1,700 people between 19.
In 1801, the Act of Union made Ireland a part of the United Kingdom.
The Catholics were suppressed through discriminatory laws and regulations, and they started several uprisings which were swiftly crushed by the police and the British Army.
To increase their control, they sent Protestant Englishmen and Scots to settle in this area and simply take over land from the Irish.
This immigration proved very effective and by 1703, less than five per cent of the land of Ulster was still in the hands of the Catholic Irish.
Why is there so much talk of Catholics and Protestants in the conflict in Northern Ireland?
The Republic of Ireland is historically a Catholic country and a large majority of the Irish are Catholics.
The English had a particularly difficult job in ruling the Irish in the northern corner of the country (called Ulster).Religious teachings are not an issue between the Catholics and Protestants. Historically, the Catholics have been poor, oppressed and often unemployed.On the other hand the Protestants have represented the oppressive British side consisting of the privileged classes in society with better jobs, brighter opportunities, and better wages.After Irish independence was a fact in 1921, the struggle continued to get Ulster back from the British.The biggest obstacle was that the majority of people in this region did not want to be liberated; they were Protestants and were happy as citizens of the United Kingdom. The Catholics felt suppressed and demonstrated for civil rights and equal treatment with the Protestants.This party has official MPs who are legally elected for Parliament in London.
