ANSWER:
Since Ireland was granted "total independence on 1949", Northern Ireland has been struck by violence that arose from conflict over "whether to reunify with the rest of Ireland".
Step-by-step explanation:
- North Ireland and South Ireland are created by the "Government of Ireland Act" in 1921, under British laws.
- This is a kind of home rule in Ireland. Northern Ireland usually consists of six countries, all falls in United Kingdom.
- To reunify, several conflicts and Bloody Sunday's and Friday's were happened, many mass murders were performed by Irish Republican Army in streets, and small towns. This resulted in more casualties in the state of Ireland.
