In 1914, the Liberal Party was the most powerful political party in Scotland but by 1918 it was divided.
The Independent Labour Party (ILP) was a significant political force in the west of Scotland
The ILP had been formed by Scottish miner Keir Hardie in the late 1880s. It was among the various organisations that formed the Labour Representation Committee (LRC) in 1900.
The LRC later became known as the Labour Party. It soon to become one of the two major political parties in the whole of the UK.
Meanwhile, the Conservative Party began to attract new voters from the middle classes living in the cities.
When war broke out in 1914, the main Labour Party supported the war effort and even joined the coalition government of 1916. The ILP was consistently opposed to Britain's involvement in the war.
The policies of the ILP were more radical than the mainstream Labour Party and eventually the two parties went their separate ways in the 1920s.
