Northern Ireland is divided politically, religiously and culturally between two competing Communities/Ideologies, Irish Nationalism and British Unionism. This Divide has existed in Northern Ireland from its creation in 1921 to modern day and is the basis for almost every single debate or issue in the country. This Divide is also responsible for the armed conflict fought in Northern Ireland from the 1960s-1990s known as The Troubles, which was a conflict fought between three main groups: Irish Republicans (More hardcore and militant Irish Nationalists that see any form of British Rule in Ireland as Illegitimate) who fought for an Independent United Ireland, Ulster Loyalists (More hardcore and military Unionists who are fiercely loyal to the British Crown) who fought to preserve Northern Ireland's status in the United Kingdom and British State Security forces such as the British Army, Police and other who fought to retain Northern Irelands position in the United Kingdom and to end armed paramilitary campaigns.
The Troubles began in the 1960s after growing discontent and sectarian violence between the minority Nationalist community and the majority Unionist Community. Nationalists were subject to constant discrimination in many areas of Northern Irish Society such as Gerrymandered Electoral boundaries to ensure Unionist political victories. A Highly sectarian police force that was almost entirely Protestant that launched attacks against Nationalists and persecuted them and favouritism towards Protestants for Jobs, Benefits, Housing and others. This all came to ahead with a Civil Rights campaign known as the Northern Ireland Civil Rights Association (NICRA) which campaigned for Equality in Northern Ireland between Nationalist and Unionists and which suffered from a fierce crackdown by the Unionist government which led to increased clashes between both communities and ultimately culminated in armed paramilitary campaigns (which consisted of mass killings, ambushes, bombings, murders, abductions and more).
Some notable armed groups from this conflict include The Irish Republican Army (Split between three main groups, Provisional IRA, Continuity IRA and the Official IRA), the Irish National Liberation Army which fought against British rule in Northern Ireland. And the Ulster Volunteer Force, Ulster Defence Association and Red Hand Commandoes which fought against Republican paramilitaries and to keep Northern Irleand in the United Kingdom.
The Troubles ended in 1998 with a peace agreement known as the Good Friday Agreement which created a new power sharing devolved executive known as the Stormont Assembly and saw an end to armed campaigns by most paramilitary groups and a restructuring of Northern Ireland to create a more equal country between Nationalists and Unionists. This also led to the removal of most British Military forces from Northern Ireland though some paramilitaries continue to operate to this day.

How the Executive Works:
Northern Irelands Executive is a power sharing executive, meaning that Nationalists and Unionists must work together in order for the executive to function. This is to prevent one community from dominating the other. The offices of First Minister and Deputy First Minister are the head offices of the executive and despite the name difference they have the same power and function. The First Minister position is held by a member of the Largest Party of the Largest Designation (I.e Unionist) and the Deputy First Minister position is held by a member of the Largest Party of the second Largest Designation (i.e Nationalist). Other Ministerial Positions can be held my members of the parties that make up the Government. Currently NI's ministers come from Five Parties, the DUP, Sinn Fein, SDLP, UUP and Alliance.
The Current First Minister and Deputy First Minister are: Arlene Foster (DUP) and Michelle O'Neil (Sinn Fein)
If either community refuses to take part in the executive it collapses and a new election must be held.
