During World War II, the British required the people in their colonies to contribute to the war effort, this included thousands of men and women from the Caribbean who served in the British Armed Forces. World War II left Britain crippled with a shortage in population, supplies and money, so it was a long rebuilding process for everyone. The war had shown both the best and worst in people and humanity in general, and also in many ways marked the beginning of the end of the British Empire, with a rapid decline in power in its colonies across the globe.
