How did the UK's involvement in World War I impact its political landscape?

The UK's involvement in World War I had a significant impact on its political landscape.

Firstly, during the war, the British government implemented a range of new policies and laws, such as conscription, which led to an increase in government control and regulation of society. This expansion of state power was a key feature of the war, and had a lasting impact on British politics.

Secondly, the war would ultimately lead to the collapse of the Liberal Party, which had dominated British politics for much of the previous century. In the general election of 1918, the party suffered a crushing defeat, losing the majority of its seats in the House of Commons. The Conservative Party, which had been in opposition for much of the war, would emerge as the dominant force in British politics.

Finally, the war had a profound effect on British society as a whole, leading to significant changes in attitudes and values. The experience of the war would shape social and political debates for years to come, both in the UK and around the world.
