After the ottomans blocked the Europeans trade routes to the Indian subcontinent and the rest of Asia Europe had to find an ocean route around Africa which put them in contact with many indigenous populations which the Europeans would colonize and enslave in order to exploit the routes they had to take to get to Asia <span />
The colonist believed they would be wealthy by the amount of land they owned
The north wanted the south to change its work gain, such as slavery and change more into industry
Colonies
Hope this helps!! :)
