Roughly seven hundred thousand enslaved workers in the British West Indies immediately become free when the Slavery Abolition Act comes into force in 1834; others will be freed several years later after a period of forced apprenticeship.
Slavery had been abolished in the Dutch Empire in 1814, and in the Spanish Empire in 1811, with the exceptions of Cuba, Puerto Rico, and Santo Domingo; Spain had ended the slave trade to these colonies in 1817, after being paid four hundred thousand pounds by Britain.
Slavery itself will not be not abolished in Cuba until 1886.
France will abolish slavery in its colonies in 1848.
