Even though World War I was fought far beyond the borders of British Guiana, the war altered Guyanese society. The Afro-Guyanese who joined the British military became the nucleus of an elite Afro-Guyanese community upon their return. World War I also led to the end of East Indian indentured service. British concerns over political stability in India and criticism by Indian nationalists that the program was a form of human bondage caused the British government to outlaw indentured labor in 1917.
