Miners' Federation of Great Britain

The Miners' Federation of Great Britain, MFGB was established in Newport, Wales in 1888 to represent and co-ordinate the affairs of local and regional miners' unions whose associations remained largely autonomous. The federation was reorganised into the National Union of Mineworkers in 1945.

The National Union of Mineworkers (NUM) is a trade union for coal miners in Great Britain, formed in 1945 from the Miners' Federation of Great Britain (MFGB). The NUM took part in three national miners' strikes, in 1972, 1974 and 1984–85. After the 1984–85 strike and the subsequent closure of most of Britain's coal mines, it became a much smaller union.
