How was the British empire involved in ww1?

The British Empire played a crucial role in World War I, contributing vast resources and manpower to the Allied war effort. At the start of the war, Britain mobilized its colonies and dominions, including Australia, Canada, India, and South Africa, providing millions of soldiers and significant financial support. The British navy dominated the seas, blockading Germany and controlling vital supply routes. Additionally, the empire's global reach facilitated the recruitment of troops from various regions, making it one of the largest military coalitions in the conflict.
