Starting after the First World War, and coming into larger effect after the Second, many nations or colonies of the British Commonwealth gained independence. Namely, India, Pakistan, and Sri Lanka in 1948. Later, in 1957, Ghana was the first sub-Saharan African colony to gain full independence. In the 60s the desire for independence spread like wildfire through many other colonies in Africa, Asia, and the Caribbean. These events were part of the catalyst and inspiration of post-colonial literature.
