Answer:
The main reason for bringing African Slaves instead of Native slaves from South America or even North America is because, they were susceptible to diseases brought by the Settlers, Africa was already used to these diseases so they were easy to bring. Furthermore, an example of this is the tragic story of Darth Plaguis the wise *AHEM* I mean pocahauntus who was brought to England on a ship but died due to disease on that ship. If one loses 70-80% of their slaves on a ship then its useless. ALSO VERY IMPORTANT your question is supposed to say 12 million not 1/2 million
Federalists. The wanted the independence.
I got this from Brittinica.com and these are the most important details from it:
'Open Door policy, statement of principles initiated by the United States in 1899 and 1900 for the protection of equal privileges among countries trading with China and in support of Chinese territorial and administrative integrity.The principle that all countries should have equal access to any of the ports open to trade in China. But after Japan’s defeat in World War II (1945) and the communist victory in China’s civil war (1949), which ended all special privileges to foreigners, made the Open Door policy meaningless.
I hope this was helpful.
