Slavery is vastly different than Racism. Racism is an attitude that can influence behavior. Slavery requires both slaves and owners. Spartacus was a slave, a European from Thrace.
America was visited in 1602 by Captain Bartholomew Gosnold who, without slaves, explored and named Cape Cod and Martha’s Vineyard. Capt. Bartholomew Gilbert voyages to Chesapeake Bay; In 1603 he and four others go ashore (likely on the Eastern Shore) and are killed by Indians, an apparently race-based killing. America was settled in 1603 in Jamestown VA.
