The Heart of Africa Mission was changed to Worldwide Evangelization Crusade (WEC) in 1919 when Mr. Gilbert Barclay, who married Studd's daughter Dorothy, became Home Overseer. He took the position on the condition that the organization have a worldwide title, scope and work. (As C.T. Studd believed God told him, on his way to Congo, "This journey is not just for Africa but for the whole unevangelised world.") Recruitment of missionaries began immediately and in 1922 WEC entered Amazonia. WEC was the parent organization and individual fields were permitted to retain their own subtitles, so the new field became Heart of Amazonia. By the time of Studd's death, the Amazonia field had 16 missionaries with headquarters and mission stations in three people groups. Central Asia was entered next, then Arabia, followed by West Africa (Spanish Guinea), and then Colombia, South America
