In 1886, Keir Hardie founded the Scottish Miners' National Federation. This was based on the Ayrshire Miners' Union, but initially had a total of 23,570 members in 26 districts. Hardie became its secretary and, through it newspaper, "The Miner", he campaigned for the nationalisation of the coal mines, a minimum wage and a five-day week. Although its membership dropped rapidly, forcing it to dissolve in 1888, several of its districts survived as independent unions.
