For a dozen years around the First World War, the shipyards, factories and tenements of Clydeside made Glasgow the most politically radical city in Britain — ‘Red Clydeside’. Rent strikes led by working-class women, shop stewards defying the wartime state, a revolutionary schoolteacher jailed for his beliefs, tens of thousands massing in George Square beneath a red flag, and finally a phalanx of socialist MPs sent south to Westminster: for a decade Glasgow alarmed the British establishment as no city had before. And in alarming it, it helped change it.
This page traces the whole arc: why Clydeside became so radical, the rent strikes, the shop stewards, the drama of George Square, the socialist MPs of 1922, and the lasting mark the movement left.
The making of Red Clydeside
Red Clydeside did not come from nowhere. Glasgow entered the twentieth century with some of the worst overcrowding in Europe, its people packed into insanitary tenements while a vast concentration of heavy industry — the shipyards, engineering shops and munitions works of the Clyde — gathered together a skilled, literate and highly organised workforce. Add the enormous strains of the First World War, with profiteering landlords, diluted wages and conscription, and the region became a tinderbox of grievance. What was needed was a spark, and in 1915 it came.
The 1915 rent strikes
With Glasgow’s munitions factories crammed with war workers, landlords saw their chance and raised the rents. The response was a rebellion of the tenements, led not by trade-union men but by the housewives of Govan and Partick under the redoubtable Mary Barbour. ‘Mrs Barbour’s Army’ blocked evictions, pelted the sheriff’s officers with flour and mounted mass demonstrations at the courts. The government, terrified of a stoppage in the munitions yards, capitulated and rushed through the Rent Restriction Act of 1915, imposing rent control across the whole United Kingdom — a stunning victory won from the closes and back courts of Glasgow.
The Clyde Workers’ Committee
In the factories, meanwhile, a militant shop stewards’ movement took shape. The Clyde Workers’ Committee resisted the wartime ‘dilution’ of skilled labour and became a thorn in the side of employers and government alike. Its leaders — among them William Gallacher, David Kirkwood and Arthur MacManus — were watched, arrested and deported from the region. Towering over them all stood John Maclean, the Marxist schoolteacher whose fiery anti-war lectures drew thousands and whose repeated imprisonments made him a martyr; Lenin himself appointed Maclean Bolshevik consul in Glasgow. Revolution, for a moment, seemed to be in the Clydeside air.
Bloody Friday
The tension broke in January 1919. A strike for a forty-hour week brought tens of thousands into George Square, where a red flag was raised and the police mounted a baton charge in what became known as ‘Bloody Friday’. Convinced that a Bolshevik rising was at hand, the government poured troops and tanks into the city, while the Scottish soldiers in Maryhill barracks were confined to quarters for fear they would side with the strikers. No one died on the day, but the sight of a British government treating Glasgow as an enemy city seared itself into the memory of the labour movement.
The Wild Clydesiders
The energy of Red Clydeside flowed, in the end, not into revolution but into the ballot box. At the general election of 1922 the Independent Labour Party swept Glasgow, returning a phalanx of socialist MPs — James Maxton, John Wheatley, Emanuel Shinwell, David Kirkwood and their comrades — who were seen off at St Enoch Station by vast crowds singing psalms and the Red Flag. These ‘Wild Clydesiders’ carried the fervour of the closes and the yards into the House of Commons, and gave Scottish socialism a national voice it had never had before.
Homes & reform
Once at Westminster the Clydesiders turned protest into law. In the first Labour government of 1924 John Wheatley, as Minister of Health, passed the Wheatley Housing Act, which unleashed the mass building of good-quality council housing that would rehouse millions across Britain in the decades to come. It was the movement’s most enduring monument: the direct descendant of Mary Barbour’s rent strikes, and proof that the anger of Red Clydeside could be forged into lasting reform.
The legend & the legacy
By the early 1930s the great days were over. John Maclean was dead, and the ILP drifted away from the Labour Party. Yet Red Clydeside left a permanent mark. It won rent control and mass council housing, it helped make Glasgow and the west of Scotland a Labour stronghold for generations, and it bequeathed a proud tradition of collective action that would surface again in later struggles on the Clyde. Half legend, half hard fact, it remains one of the defining chapters in the city’s history.

Frequently asked questions
What was Red Clydeside?
Red Clydeside was a period of intense political radicalism and labour militancy in Glasgow and the surrounding Clyde region in the early twentieth century, marked by rent strikes, industrial action, mass demonstrations and the rise of socialist politics.
When was Red Clydeside?
Broadly from around 1910 to 1932, reaching its height during and just after the First World War. Its landmark moments were the 1915 rent strikes, the Battle of George Square in 1919, and the election of a wave of socialist MPs in 1922.
Why was Clydeside so radical?
A combination of appalling housing and overcrowding, a huge concentration of heavy industry with a skilled and organised workforce, and the strains of the First World War — profiteering, wage dilution and hardship — created deep grievances and the organisation to act on them.
What were the 1915 rent strikes?
A mass revolt against wartime rent rises, led by working-class women under Mary Barbour in Govan and Partick. Their resistance to evictions forced the government to pass the Rent Restriction Act of 1915, introducing rent control across the United Kingdom.
What was the Battle of George Square?
A confrontation on 31 January 1919 — ‘Bloody Friday’ — when a strike rally of tens of thousands in George Square was broken up by a police baton charge. Fearing revolution, the government sent troops and tanks into Glasgow in the days that followed.
Who were the Red Clydesiders?
They included figures such as John Maclean, Mary Barbour, William Gallacher, David Kirkwood, James Maxton and John Wheatley. Many of the Independent Labour Party leaders were elected to Parliament in 1922 as the ‘Wild Clydesiders’.
What did Red Clydeside achieve?
It won rent control in 1915 and, through John Wheatley’s Housing Act of 1924, the mass building of council housing. It also helped make the west of Scotland a Labour heartland and left a lasting tradition of collective action.
