Answer
The mass deportation of Ghanaian migrants in 1983, ordered by President Shagari, was a significant event in Nigerian history. The decision was fueled by economic challenges and rising unemployment, leading the government to target foreign nationals, particularly Ghanaians, who were perceived to be taking jobs from Nigerian citizens. Over one million Ghanaians were affected, many of whom had lived in Nigeria for years, contributing to the country's economy and society.
