Elizabeth or Betty Sinclair was born into a working-class Protestant family in the Ardoyne area of North Belfast in 1910. Her father worked at the world-famous, Harland and Wolff Shipyard and was known as a Socialist-Unionist. Betty’s mother was a Reeler in Ewart’s Mill on the nearby Crumlin Road.
After leaving school at fifteen, Betty became a millworker alongside her mum. Like her father, she became an active Trade Unionist and joined the Revolutionary Workers’ Group (RWG) in 1932. A year later RWG established the Communist Party of Ireland (CPI), with Sinclair as one of its founding members.
Betty cut her political teeth during the Outdoor Relief Protests between1932 – 1935. When Belfast Nationalists and Unionists joined together and demanded an improvement in benefits for the unemployed. Betty and other Socialists were violently opposed on the streets by amongst others, the RUC and the Ulster Protestant League (UPL). The UPL was a Loyalist organisation that regularly claimed the ongoing strike was, ‘but a cloak for Sinn Fein Communists who wanted to destroy our province’. It also congratulated the Unionist Regime, RUC and British Army whenever demonstrations by tens of thousands of unemployed workers were brutally broken-up. On one occasion, two demonstrators were shot dead during a non-sectarian rally.
Afterwards, Betty attended the Lenin School in Moscow. As one of its students, she was taught working-class history, imperialist and Soviet economies and Marxist theory. When the All-Ireland CPI dissolved in 1941, Sinclair remained an active member of the Communist Party of Northern Ireland (CPNI) and served as its Secretary from 1942 to 1945. She was also jailed for sedition in 1941 after a sympathetic Irish Republican Army (IRA) article was published in the Party’s newspaper, Unity.
She later stood for the Party in Belfast’s Cromac constituency at the General Election in 1945, taking almost one third of vote cast. She was later elected to the Belfast and District Trade Union Council and was its Secretary from 1947 to 1975.
Sinclair was the Trades Council's representative at talks which founded the Northern Ireland Civil Rights Association (NICRA) in 1967 serving as its first Chairperson until 1969, when she resigned claiming it had become dominated by Ultra-Leftists that added to sectarian divisions.
After 1969 she travelled throughout Eastern Europe and in the 1970s lived in Prague as the Irish representative on the editorial board of World Marxist Review. Sadly, she died in 1981 after a lethal fire at her flat in East Belfast. Betty Sinclair was an Irish Revolutionary, Communist and Internationalist. Who played a major role in the struggle for Civil Rights, Equality and Freedom in Ireland and internationally.
