Why was Olaudah Equiano's name changed to Gustas Vassa?

Olaudah Equiano changed his name to Gustavus Vassa after being baptized in 1759. It is believed that he chose this name in honor of Gustavus Vasa, a 16th-century Swedish king known for leading a successful rebellion against Danish rule. Equiano likely admired the king's fight against oppression and saw similarities with his own experiences as a former slave advocating for abolition.
