In the first days of April 1820, Scotland experienced a dramatic and often overlooked moment of unrest now known as the Radical War, or the Radical Rising. It lasted only about a week, but it brought together economic hardship, political frustration, and demands for change in a way that left a lasting mark on Scottish history. National Records of Scotland describes it as a week of strikes and unrest that ended with treason trials, while modern historians place it firmly in the wider story of political reform in 19th-century Scotland.
To understand why it happened, it helps to look at Scotland after the Napoleonic Wars. The years after 1815 were difficult for ordinary working people. Economic recession, unemployment, falling wages, and high food prices created real distress. Historic Environment Scotland notes that the Corn Laws helped keep grain prices high, while demobilisation after the wars added huge numbers of men to an already strained labour market. At the same time, political power was held by a tiny elite. National Records of Scotland says there were fewer than 3,000 parliamentary electors in all of Scotland, and Historic Environment Scotland notes that only about 0.2 percent of the population had the vote.
That combination of poverty and exclusion made reform feel urgent. Many radicals wanted universal male suffrage, annual parliaments, and a political system that better represented ordinary people. The example of the American and French revolutions had already inspired reformers across Britain, and the outrage after the Peterloo Massacre of 1819 gave fresh energy to the movement. In Scotland, protest meetings and radical societies spread through industrial communities, especially among weavers and other skilled workers.
The rising itself was shaped not only by genuine anger, but also by government surveillance. National Records of Scotland says it is now generally accepted that government agents infiltrated the radical movement. One of the most important figures was John King of Anderston, described as a government spy who helped push events toward a confrontation. According to the records, after the arrest of leading radicals, a proclamation appeared in Glasgow on 1 April 1820 calling on people to stop work and take up arms in pursuit of their rights.
The response was significant. Historic Environment Scotland records that on Monday 3 April 1820, about 60,000 workers went on strike across a wide area of central Scotland. Many of the participants were artisan workers, especially weavers, and some had military experience from the Napoleonic Wars. Weapons were gathered or improvised, foundries and forges were targeted for materials, and military-style drilling took place in some areas. What began as a strike movement quickly took on the appearance of a broader insurrection, though support was uneven and coordination was weak.
The best-known clash of the Radical War came at Bonnymuir near Bonnybridge on 5 April 1820. A group led by Andrew Hardie and John Baird had been directed toward the Carron Ironworks, where they hoped to secure weapons, but the plan depended on support that never properly arrived. Historic Environment Scotland says Hardie and Baird had only around 30 men with them when they were persuaded to continue. Government troops, including yeomanry and soldiers moving through the Stirling area, converged on them at Bonnymuir. After a short fight, the radicals were defeated and many were captured.
The aftermath was severe. National Records of Scotland states that 88 bills of treason were issued, though only a smaller number of men were ultimately tried because many had fled. The authorities wanted to make an example of those involved. At Stirling, Andrew Hardie and John Baird were convicted of treason. Historic Environment Scotland records that most of the Bonnymuir prisoners eventually had their death sentences commuted to transportation for life, but Baird and Hardie were hanged and beheaded in Stirling on 8 September 1820. James Wilson, another radical associated with the movement, was also executed.
Because the rising failed so quickly, it can be tempting to dismiss it as a minor episode. Britannica even describes it as an abortive rising of workers in the Glasgow area. But that would miss its real significance. The Radical War exposed the depth of discontent in industrial Scotland and showed how fragile the political system could become when ordinary people were denied representation. It also became part of the longer story that led toward reform. Historic Environment Scotland points out that although the 1832 Reform Act expanded the electorate, it still left around 400,000 adult men in Scotland without the vote and excluded all women, meaning the struggle was far from over.
The memory of 1820 also changed over time. For years, the radicals were often treated as dangerous rebels, but later generations increasingly saw them as early reformers. Historic Environment Scotland notes that campaigner Peter Mackenzie published a book in 1832 arguing that government spies and agents provocateurs had played a central role in the rising. The government later lost a libel case connected to those claims, and in 1835 an absolute pardon was issued to the insurgents. That helped reshape public memory, turning the men of 1820 from traitors in official eyes into martyrs of reform in popular memory.
Today, the Radical War of 1820 is still less widely known than Jacobite history or the Wars of Independence, but it deserves attention. It was not a romantic Highland rebellion or a clash between kingdoms. It was a modern political crisis rooted in wages, food prices, voting rights, and industrial society. In that sense, it feels strikingly relevant. The men who marched in early April 1820 were not simply looking backward to an older Scotland. They were demanding a different future.
