Encyclopedia of Free Blacks and People of Color in the AmericasWhen Columbus arrived in 1492, the first free black person --a sailor -set foot in the Americas. Over the next 400 years, as slavery spread and became entrenched in the Western Hemisphere, free blacks built communities throughout North and South America, playing a critical role in every region, colony, and country. From Canada to the Caribbean to Chile, they established vital economic and social institutions, championed the cause of abolition, and formed a bridge between the worlds of free whites and enslaved blacks.
