Brazil was the last American nation to abolish slavery, on 13 May, 1888. At the time Rio represented the largest urban concentration of slaves since the end of the Roman empire, more than 40% of the population, almost a complete city in irons.
An estimated 4.9 million slaves from Africa were brought to Brazil during the period from 1501 to 1866. Until the early 1850s, most enslaved Africans who arrived on Brazilian shores were forced to embark at West Central African ports, especially in Luanda (present-day Angola).
