In the inter-war years, groups of enterprising Yoruba traders from a few towns in Western Nigeria established a successful trading network throughout the Gold Coast (Ghana). Then, in 1969, they were abruptly ordered to leave the country. At the time of the exodus, Jerry Eades followed the traders back to Nigeria. There, on the basis of extensive interviews and archival sources, he reconstructed the history of the migration from four Yorubu towns to northern Ghana. The result is one of the fullest and most detailed accounts of chain migration and its implications for economic development ever written.
