Billy McKee (Irish: Liam Mac Aoidh), Irish republican and a founding member and leader of the Provisional Irish Republican Army, is born on November 12, 1921, in Belfast, Northern Ireland.

McKee joins Fianna Éireann in 1936. He is arrested following a raid on a Gaelic Athletic Association (GAA) club in 1938, being imprisoned in Crumlin Road Gaol for several months. Following his release from prison, he joins the Irish Republican Army (IRA) in 1939. During World War II, the IRA carries out a number of armed actions in Northern Ireland known as the Northern Campaign. He is arrested and imprisoned in Crumlin Road Gaol until 1946 for his role in this campaign. In 1956, the IRA embarks on another armed campaign against partition, known as the Border Campaign. He is again arrested and interned for the duration of the campaign. He is released in 1962.

Upon release, McKee becomes Officer Commanding (OC) of the IRA’s Belfast Brigade. However, he resigns this position in 1963, after a dispute with other republicans due to him acceding to a Royal Ulster Constabulary (RUC) demand that he not fly an Irish tricolour during a republican march. He is succeeded by Billy McMillen.

As the 1960s proceed, McKee drifts away from the IRA. He grows very disillusioned with the organisation’s increasing emphasis on socialism and reformist politics over “armed struggle.” He is a devout Roman Catholic, who attends Mass daily. As a result, he is very uncomfortable with what he feels are “communist” ideas coming into the republican movement.

During the 1969 Northern Ireland riots, severe rioting breaks out in Belfast between Irish Catholic nationalists, Protestant loyalists, and the RUC. McKee is highly critical of the IRA’s failure to defend Catholic areas during these disturbances. On August 14, 1969, McKee, Joe Cahill and a number of other Irish Republican activists occupy houses at Kashmir Street, however, being poorly armed they fail to prevent Irish Catholics in Bombay Street and parts of Cupar Street and Kashmir Street being driven from their homes in the sectarian rioting that engulfs parts of the city. In the aftermath of the riots, he accuses Billy McMillen, the IRA’s Belfast commander, and the Dublin-based IRA leadership, of having failed to direct a clear course of action for the organization in civil disturbances. On September 22, 1969, he and a number of other IRA men arrive with weapons at a meeting called by McMillen and try to oust him as head of the Belfast IRA. They are unsuccessful but announce that they will no longer be taking orders from the IRA leadership in Dublin. In December 1969, the IRA splits into the Provisional IRA which is composed of traditional militarists like McKee, and the Official IRA which is composed of the remnants of the pre-split Marxist leadership and their followers. He sides with the Provisionals and joins the IRA Army Council in September 1970.

McKee becomes the first OC of the Provisional IRA Belfast Brigade. From the start, there is intermittent feuding between McKee’s men and his former comrades in the Official IRA, as they vie for control of nationalist areas. However, the Provisionals rapidly gain the upper hand, due to their projection of themselves as the most reliable defenders of the Catholic community.

McKee himself contributes greatly to this image by an action he undertakes on June 27, 1970, the Battle of St Matthew’s. Rioting breaks out in the Ardoyne area of north Belfast after an Orange Order parade, and three Protestants are killed in gun battles between the Provisional IRA and loyalists. In response, loyalists prepare to attack the vulnerable Catholic enclave of Short Strand in east Belfast. When McKee hears about this, he drives to Short Strand with some men and weapons and takes up position at St Matthew’s Church. In the ensuing five-hour gun battle, he is wounded and one of his men is killed, along with at least four Protestants.

On April 15, 1971, McKee, along with Proinsias Mac Airt, is arrested by the British Army when found in possession of a handgun. He is charged and convicted for possession of the weapon and imprisoned in Crumlin Road Gaol, and Joe Cahill takes over as OC of the Belfast Brigade.

In 1972, McKee leads a hunger strike protest in an effort to win recognition of IRA prisoners as political prisoners. Republicans who are interned already have special status, but those convicted of crimes do not. On June 19, the 35th day of hunger strike, he is close to death, William Whitelaw concedes Special Category Status (SCS) which, although not officially awarding political status, is tacit recognition of the political nature of the incarceration. Prisoners wear their own clothes, have no prison work, can receive one visit and food parcel per week and unlimited letters.

McKee is released on September 4, 1974, and resumes his position as OC of the Belfast Brigade. At this time the Provisional IRA calls a ceasefire, and he is involved, with Ruairí Ó Brádaigh, in secret peace talks in Derry with the Northern Ireland Office. He is also involved in talks with Protestant clergy in Feakle, County Clare, in December 1974, where he voices his desire to end the violence.

However, in the same period, McKee authorises a number of sectarian attacks on Protestants as well as renewed attacks on rival republicans in the Official IRA. For this he is heavily criticised by a group of Provisional IRA activists grouped around Gerry Adams.

A faction led by Adams manages to get McKee voted off the IRA Army Council in 1977, effectively forcing him out of the leadership of the organisation. His health suffers in this period, and he does not resume his IRA activities. He joins Republican Sinn Féin after a split in Sinn Féin in 1986. At age 89, reflecting on his involvement in the Republican cause he says, “From the time I was 15 until 65 I was in some way involved. I have had plenty of time since to think if I was right or I was wrong. I regret nothing.”

In later years McKee, Brendan Hughes and Tommy McKearney are critical of the Belfast Agreement and of the reformist politics of Sinn Féin. In 2016 he sends a message of support to the launch of the hardline new Republican party Saoradh, reportedly the political wing of the New IRA.

McKee dies in Belfast at the age of 97 on June 11, 2019. His funeral takes place on June 15, 2019, in west Belfast. His coffin is carried on a gun carriage. He is buried in Milltown Cemetery.
