Hi, my grandfather used to work in a cotton plantation. 
wow, which one?
In a Minnesota plantation. But it is closed now, because of slavery issues.
Slavery was still legal when independence was declared in 1776
Yea I am glad its abolished now. It was a very bad system.
Yeah it was. Apparently slavery started in ancient Mesopotania
Did it? I thought it started in Egypt. Does slavery still exist in parts of the world?
I'm not sure but it's rare among simple tribes because it was invented as a hierarchy
I see, but now there are better to implement a hierarchy than to make people slaves!
Catholic Church and slavery
The issue of slavery was one that was historically treated with concern by the Catholic Church. Throughout most of human history, slavery has been practiced and accepted by many cultures and religions around the world. Certain passages in the Old Testament sanctioned forms of slavery. The New Testament taught slaves to obey their masters, but this was not an endorsement of slavery, but an appeal to Christian slaves to honor their masters and accept their suffering for Christ's sake, in imitation of him. In proclaiming baptism
of the United States abolished slavery, partly in response to the Declaration of Independence, between 1777 and 1804. Britain ended slavery in its empire in the 1830s. However, the plantation economies of the southern United States, based on cotton, and those in Brazil and Cuba, based on sugar, expanded and grew even more profitable. The bloody American Civil War ended slavery in the United States in 1865. The system ended in Cuba and Brazil in the 1880s because it was no longer profitable for the owners. Slavery continued
