Under the leadership of Prime Minister H. H. Asquith, the British Liberal Party struggled to cope with the immense pressures of World War I. Initially, Asquith's government enjoyed substantial support as Britain entered the war, aimed at preserving democracy and defeating autocratic regimes. However, as the war dragged on, the realities of trench warfare and high casualty rates began to erode public confidence in the Liberal administration.

By mid-1915, Asquith faced intense criticism over military failures, logistical issues, and a perceived lack of decisive action. Calls for a more cohesive war effort emerged, with many politicians advocating for a broader coalition government to unite various political factions. The escalation of military challenges, such as the Gallipoli Campaign, which had ended in disappointment, further strained the government's credibility. On 17 May 1915, the internal dissent within the Liberal Party and a growing sense of urgency for a united front forced Asquith to announce the resignation of his government.

The resignation marked a pivotal moment as it opened the door for new leadership. It led to the formation of a coalition government, with David Lloyd George emerging as a key figure. The shift in power signaled significant changes in British politics during wartime, as it was clear that more extensive collaboration was necessary for a successful war effort.
