How did the transatlantic slave trade affect the colonies?

In order to earn profit and provide for their mother country, America used slaves brought from Africa to produce cotton and other raw materials.
In order to get the slaves to the Americas, ships devised a trade route system known as The Transatlantic Slave Trade, or simply The Triangular Trade.

From Europe to Africa

Transatlantic Slave Trade

The triangular trade would be used to describe the transport of goods and not necessarily the transport of ships.
What that means is that most ships would not make round trips but rather back and forth from the two points of the triangle.
Some items that would be transported from Europe to Africa was things like rum or processed materials that would be exchanged for slaves.
Then the slaves be shipped to the Americas.

Arrival and Departure in Africa

When the European businessmen from Europe arrived at Africa,
the slave markets would open and slaves would be forced to move onto cramped ships where they only had about six by two feet of moving space.
They could only only lie down and only the small people could move in the provided space.
These ships would house hundreds of slaves housed inside.

Slave Markets in the West Indies and Caribbean

The Middle Passage

The Middle Passage,
known for its cruelty to those who travel along the treacherous Atlantic.
Almost 70 thousand traveled along the middle passage in cramped ships.
Diseases weren't uncommon and a quarter of the passengers aboard would die of starvation or infectious diseases.
When the survivors from the Middle Passage would arrive in the new world,
they would be brought to slave markets in the West Indies and some countries around it.
Then they would be sent from there to docks in the Southern slaves to be collected and sold to white auctioneers.
Families would be separated in the process.

Slavery in the South

Once slaves had arrived from their long journey past oceans and auctions,
the white plantation owners would put them to work.
They would wake up early in the morning and begin working in the cotton fields.
If they didn't do sufficient work,
they would be whipped or sometimes killed.
Women were given a higher priority than men because men would sometimes ignore rules and directions.
Often times,
women would be abused to procreate so that the land owners wouldn't have to go and buy more slaves from the market.
Many Northerners supported the abolition of slavery.

From the Americas to Europe

Goods such raw materials like cotton from America would be shipped to Europe where it could be processed and then brought down to Africa where the cycle would begin again.
Sometimes,
it wasn't always raw materials that would be sent to Europe.
Gold and exotic foods from the Americas would be sent to Europe in a process known as mercantilism.
That means that the mother country would be provided food and other supplies by its child country.
Since the Europeans colonized America,
the country was "theirs".
Many colonists were not happy that they had to give up so much to Europeans.
They were living like kings whilst the colonists had to work very hard.
The triangle was completed when the goods were transported back to Europe.
Those goods would be brought to Africa and so on.
