Answer:
He is writing to white Christians with the power to stop the slave trade
Explanation:
Olaudah Equiano was a notable Nigerian sold into slavery and taken to the Caribbean and then to London.
In his memoirs, he recounts how he wrote to white Christians who had the power to stop the slave trade but could not stop it because so many people were benefitting from the trade.
The treatment of slaves were inhuman and debasing as they were whipped deprived of food made to move about naked, and a lot of other injustice.
Hence, his letter was directed to white Christians who could stop the slave trade.
