The date and location of the summit was announced by British Prime Minister David Cameron in November 2012.[1][8] According to Mark Simpson, the BBC's Ireland Correspondent, the British Government chose Fermanagh for two main reasons: history and geography.[1] Since the formation of Northern Ireland in 1921, there has been tension and violence between its two main communities. The unionist/loyalist community (who are mostly Protestant) generally want Northern Ireland to remain within the United Kingdom, while the Irish nationalist/republican community (who are mostly Catholic) generally want it to leave the United Kingdom and join a united Ireland. From the late 1960s until the late 1990s, these two communities and the British state were involved in an ethno-nationalist conflict known as the Troubles, in which over 3,500 people were killed.
