Because they would get money.
Harriet Tubman's most obvious opponents were slave codes of the day, and her the slave owner. The laws offered owners rights and the means to buy, sell, and claim Harriet Tubman as personal property.
History only reports that the first slave arrived in the colonies in 1609. Not who owned him or who sold him.
europeans would sail to Africa with their boats loaded with guns, alcohol etc (traditional british items). When they got to Africa they would exchange the guns, alcohol etc for human slaves. (at least at the start, as the slave trade progressed the sailors started to capture their victims) Then with their boats full of slaves they would sail to west indies/ south America and sell the slaves in exchange for coffee, gold, sugar. Then they would sail home and sell the coffee, gold, sugar for huge profit. This was known as the slave triangle.
In Africa, there would be wars, the winners would take prisoners of war and would sell them to European traders who would sell them in the Americas to plantation owners who would use the slaves as free labor
There is still plenty of slavery around, independent of the official chattel slavery that was formally outlawed in the UK and then the US. The exploitation of drug-addicted teenage girls in some of our Inner Cities is in every way slavery. Another answer: Before the Civil War slaves had children. They had lots of children. They were encouraged to have children. The owners made it real easy for female slaves to get pregnant so they would have babies. If a slave owner had a lot of slaves he could sell the excess and make a lot of money. After the slaves were freed, they liked being able to get married and away from having to breed.
The purchased them at slave auctions. Owners that had more slaves than they needed, and those bringing them from Africa would sell them at slave markets.
A slave auction was the process used to sell slaves to slave owners. Slaves were presented and bid on like property.
Some slave owners traded slaves for goods, including sugar, as a form of payment or exchange. Slaves were often treated as commodities and could be sold or traded for various goods depending on the specific circumstances and agreements made by the owner.
When slaves were brought ashore from slave ships, they were usually inspected, cleaned, and separated before being sold at auctions. The slaves were then auctioned off to the highest bidder, typically plantation owners or slave traders, who would then use them for labor in fields, mines, or households.
Slave ship owners benefited from the slave trade financially by making profits from the sale of enslaved people. They also gained power and influence in society through their involvement in the trade, which helped them maintain and expand their wealth. Additionally, slave ship owners contributed to the growth of industries and economies that were built on the exploitation of enslaved labor.
Slave traders obtained slaves through illegal activities such as kidnapping or by exploiting vulnerable populations within countries where slavery was still practiced. They also engaged in human trafficking, particularly in regions where poverty and corruption allowed for the exploitation of individuals.

Plantation owners preferred African slaves over indentured servants because slaves were seen as a more permanent and cost-effective labor source. Slaves were considered property for life, providing long-term labor stability, while indentured servants worked for a defined period before gaining freedom. Additionally, racial prejudices and laws made it easier to control and subjugate African slaves compared to European indentured servants.
They had no protection from this. They were at the mercy of their owner. If he wanted to punish the slaves or was just ruthless, he would break apart the family and sell the other members to different slave owners.
