For clarification, Barclays bank is a British bank still operating in the UK. As part of the British empire during the colonial era, Barclays had branches in Nigeria and was called Barclays bank of Nigeria Limited. In 1972, the federal government of Nigeria acquired 51.67% ownership of the bank leaving about 40% to Barclays Bank PLC of London. In 1979, when things began to change for the worse in Nigeria, the bank sold its remaining 40% ownership to Nigerian individuals and business and left the shores of the country. After the Britain pulled out completely, this bank became known as Union Bank of Nigeria.
