Owen Martin O'Hagan was a former member of an army which emerged in what year?
Official Irish Republican Army The Official Irish Republican Army or Official IRA (OIRA) was an Irish republican paramilitary group whose goal was to remove Northern Ireland from the United Kingdom and create a "workers' republic" encompassing all of Ireland. It emerged in December 1969, shortly after the beginning of the Troubles, when the Irish Republican Army split into two factions. The other was the Provisional IRA. Each continued to call itself simply "the IRA" and rejected the other's legitimacy. Unlike the "Provisionals", the "Officials" were Marxist and worked to form a united front with other Irish communist groups, named the Irish National Liberation Front (NLF). The Officials were called the NLF by the Provisionals and were sometimes nicknamed the "Red IRA" by others.
John McMichael John "Big John" McMichael (9 January 1948 – 22 December 1987) was a leading Northern Ireland loyalist who rose to become the most prominent and charismatic figure within the Ulster Defence Association (UDA) as the Deputy Commander and leader of its South Belfast Brigade. He was also commander of the organisation's cover name, the "Ulster Freedom Fighters" (UFF), overseeing an assassination campaign against prominent republican figures whose details were included in a notorious "shopping list" derived from leaked security forces documents. The UDA used the UFF name when it wished to claim responsibility for attacks, thus allowing it to remain a legal paramilitary organisation until August 1992 when it was proscribed by the British Government.
