It goes without saying that Northern Ireland has a troubled history, for 30 years loyalists mainly Protestants fought to keep Northern Ireland in the United Kingdom but on the flip side there were republicans, mainly Catholics who fought for a united Ireland. Nearly 4,000 people lost their lives as a result of this conflict.

In 1998 the Good Friday peace agreement was signed and with it what is known as the troubles came to an end. The border between north and south became invisible and military checkpoints disappeared. However in 2016 the British people shocked just about everyone when then voted in Brexit, meaning they would be leaving the European Union.

As the UK and EU figure out how to finalise that divorce what to do with Northern Ireland becomes one of their most pressing problems as this could reignite a bitter conflict.
