Below is the timeline of when other countries in America ended slavery:
1813: In Argentina, the Law of Wombs was passed on 2 February, by the Assembly of Year XIII. The law stated that those born after 31 January 1813 would be granted freedom when contracting matrimony, or on their 16th birthday for women and 20th for men, and upon their manumission would be given land and tools to work it. Slavery finally ends in 1853.
1814: Uruguay, before its independence, declares all those born of slaves in their territories are free from that day forward.
1819: Upper Canada: Attorney-General John Robinson declares all black residents of Canada free.
1821: Gran Colombia (Ecuador, Colombia, Venezuela, Panama) declares free the sons and daughters born to slave mothers, sets up program for compensated emancipation.
1823: Chile abolishes slavery.
1831: Bolivia abolishes slavery.
1847: The last slaves in the Swedish colony Saint Barthelemy are freed. So Sweden effectively had slavery until that date.
1848: Slavery abolished in all French and Danish colonies. So France and the Denmark had slavery until that date.
1853: Argentina abolishes slavery when promulgating the 1853 Constitution.
1854: Peru abolishes slavery.
1854: Venezuela abolishes slavery.
1873: Slavery abolished in the Spanish colony of Puerto Rico.
1886: Slavery abolished in Cuba.
1888: Brazil enacts the Golden Law, decreeing the total abolition of slavery with immediate effect.
“Many blacks were born in Mexico and followed their parents into slavery.”
Ok so how do you define “many”?
Brazil, Peru, Colombia, Venezuela and Ecuador have very sizeable black populations. Brazil’s black population outnumbers America’s actually.
But Mexico? I lived there for 10 years and the only black I ever saw was a member of the Harlem Globetrotters traveling team.
You’re going to need to pull a rabbit out of your hat to back up your claim that “Mexico probably enslaved more Africans than any other colony in the Western Hemisphere”.
Nothing could be further from the truth.
