The Labour Protection League was a trade union organising dockers and stevedores in the United Kingdom.
Founded in 1871, the League was inspired by the North East Nine Hours League. After winning several small strikes over wages in its first year, the union grew to 30,000 members.
The organisation split in the aftermath of the London Dock Strike of 1889, most members leaving to form the Amalgamated Stevedores' Labour Protection League.[3] Meanwhile, Harry Quelch founded the South Side Labour Protection League, which was later named the Labour Protection League again. This was one of the unions which came together to form the Transport and General Workers' Union in 1922.
