Ghana Must Go, was a popular name given to the migration of illegal Migrants (mostly Ghanaians) from Nigeria following a Presidential executive order.
In 1983, the President of Nigeria, Shehu Shagari issued an executive order mandating immigrants without proper immigration documents to leave the country or they would be arrested according to the law. The order was in alleged response to the religious disturbances that had engulfed parts of the country in 1980 (Kano 1980 Riots ) and 1981. Most of the immigrants were West Africans and mainly Ghanaians. Over 2 million men, women and children were affected.
