The UK miners' strike, which began in March 1984 and lasted until March 1985, was a major industrial action by the National Union of Mineworkers (NUM) against the Conservative government's plans to close unprofitable coal mines. The strike aimed to protect jobs and communities dependent on coal mining, leading to widespread protests and significant social unrest across the country. The conflict was marked by violent clashes between striking miners and police, as well as a national debate over the future of the coal industry. Ultimately, the strike ended without a formal agreement, leading to the decline of the coal industry and significant changes in the UK's energy policy and labor relations.
