The formation and split of the Provisional IRA transformed a weakened Irish Republican Army into a breakaway movement explicitly committed to armed resistance. The rupture grew out of the violence of 1969, disputes over whether political action or the gun could deliver change, and the organization’s failure to protect Catholic communities. It was not a clean division between politics and violence: the new movement’s later inclusion of women and eventual turn toward electoral campaigning show how its methods continued to change.

Crisis in Belfast

The immediate setting was a city divided by neighbourhood and street. The Falls Road was a Catholic stronghold, while the Shankill Road was Protestant; narrow cross streets linked the two, with Catholic territory giving way to Protestant territory along the way. During the 1969 riots, barricades hardened these boundaries. Later, peace walls would replace many of them, making the separation visible in steel and concrete.

The political grievance behind the unrest was longstanding discrimination against Catholics in Northern Ireland. On 1 January 1969, student protesters set out from Belfast to march roughly seventy miles to Derry, challenging that injustice through peaceful protest. Some marchers believed confrontation might expose the authorities’ response and help force change; others hoped political action could redraw the conflict’s lines, away from Catholics against Protestants and toward young people against an older order. The experience of protest and violence formed part of the setting in which armed resistance gained force, but the march itself did not determine the later split.

By the summer of 1969, the Irish Republican Army was ill-prepared to defend Catholic residents as loyalist mobs burned families out of their homes. The organization had lost support after a failed border campaign in the 1950s and early 1960s, and some of its Dublin leadership had turned toward Marxist ideas and peaceful political resistance. In Belfast, only about a hundred members remained. Many were veterans, including Albert Price, but the organization was conspicuously short of weapons: in 1968 it had sold some of its remaining arms to the Free Wales Army. Its inability to protect the community fed a bitter judgment on the streets that its initials meant it had run away.

The Cyprus Street rupture

In September 1969, Belfast commander Liam McMillen convened a leadership meeting in a room on Cyprus Street. McMillen was widely blamed for the failure to defend the community during the riots. Twenty-one armed men burst into the meeting, led by Billy McKee, a veteran republican who had spent time in prison in every decade since joining the movement’s youth wing at fifteen. McKee challenged McMillen’s authority and accused him of being a Dublin communist. The confrontation made visible a factional conflict already taking shape: some members wanted to restore the IRA as an instrument of violent change, while others had moved toward a more political course.

By early 1970, a breakaway organization had formed as the Provisional IRA, committed explicitly to armed resistance. The older organization became the Official Irish Republican Army. In Belfast, people called the two wings the Provos and the Stickies. The nicknames referred to how members wore Easter lilies: the more politically inclined Officials supposedly used adhesive, while the Provos pinned paper lilies to their shirts. The distinction was more than a sartorial joke. It marked a bitter disagreement about whether political participation would dilute revolutionary aims, and whether armed defense remained essential. The division did not end violence: the two wings fought loyalist groups and British forces, and also turned against one another.

Membership and methods change

The new organization’s development was not limited to the choice between armed action and politics. In 1971, Dolours Price approached a local commander and asked to join. She was sworn in at her family home, pledging to promote the IRA’s objectives and obey orders from superior officers. Her initial proposal to join the women’s auxiliary was rejected by her own ambition: she wanted to serve as a fighting soldier, not be confined to support work. A special meeting of the Provisional IRA’s Army Council then determined that women could join as full members for the first time. Price’s republican family background and insistence on equal participation helped press the change; she also later suggested that the mass imprisonment of men may have made women’s admission a practical necessity.

The decision altered the organization’s formal boundaries, though not necessarily its daily treatment of recruits. Soon after her induction, Price was ordered to scrub a heap of filthy, mismatched, rusty bullets with steel wool. She considered the task menial and suspected it was a test, but obeyed the order she had sworn to follow. Her experience shows the distance between formal membership and actual equality, as well as the discipline the organization expected from its members.

From armed resistance to electoral politics

The split’s argument over political action persisted into later decades. During the 1981 hunger strike, the death of nationalist MP Frank Maguire created a by-election in Fermanagh and South Tyrone. Republicans proposed that hunger striker Bobby Sands run for the vacant seat, turning a prison protest into an electoral campaign. Sands’s candidacy marked a departure from the movement’s longstanding suspicion of parliamentary politics and abstentionism. His success helped demonstrate how an election could amplify the prisoners’ cause and influence the strategy that followed.

By 1983, Gerry Adams, Price’s former commanding officer, was seeking election to Westminster for West Belfast. He promised to boycott Parliament if elected, retaining an element of republican abstentionism while taking part in elections. Price campaigned for him, urged voters to support Sinn Féin, and drove people to polling stations. Adams won. Her work on his campaign embodied a later adaptation of republican politics: electoral activity had joined armed struggle rather than simply replacing the movement’s earlier history.

A divided aftermath

The Good Friday Agreement brought an end to the period of large-scale violence, but the social divisions that had formed the backdrop to the split remained conspicuous. Nearly two decades after the agreement, Belfast’s peace walls were more numerous than at the height of the conflict. Slurs on opposite sides of the barriers continued to mark Catholics and Protestants as enemies. More than 90 per cent of children in Northern Ireland still attended segregated primary schools, and residents in some parts of Belfast walked farther to wait at a bus stop where they would feel safer. Union Jack flags remained common in Protestant neighbourhoods; Catholic areas displayed the tricolour and sometimes Palestinian flags, expressing solidarity and a continuing sense of occupation.

The split therefore belongs both to the history of the armed movement and to the longer story of political adaptation. It began amid failed protection, inadequate weapons, and disagreement over the legitimacy of political strategy. Its consequences included an organization built for armed resistance, a change in who could join it as a full member, and later campaigns that used elections to pursue republican aims. The boundaries between communities and between political and armed action remained contested long after the original rupture.
