Slave
Derives from the Latin word for "Slavic". The Slavics are Europeans who were enslaved throughout history by the Greeks and Romans (who sold them to Arabs and Africans in North Africa and Spain), the Vikings, and even the Germans and Russians (in more recent times). So although ignorant people will use the term "slave" to disparage people of African descent, the term is actually more associated with Europeans.
Example:
"I never knew that the Slavics were slaves to the Greeks and Romans centuries ago until I did some research on it".
"I never knew that the Slavics were slaves to the Greeks and Romans centuries ago until I did some research on it".
