i think rome was tradeing on silk rode because Silk Road, also called Silk Route, ancient trade route, linking China with the West, that carried goods and ideas between the two great civilizations of Rome and China.
Well before slavery in America, there was an agreement of some sort where people would come to the new land poor and work for them for at least 7 years, however, America started to think "What if we had PERMANENT slaves which we could treat however we wanted” and then they sailed to Africa where they traded with the African leader for Negros to use.”
I think the answer to this problem is c not sure tho!
Gasden Purchase--the strip of land purchased from Mexico in 1853 was negotiated by James Gasden.
The US wanted this strip of land to complete the southern branch of the Transcontinental Railroad. Gasden was the minister to Mexico and sent to negotiate the purchase of the land as well as create a final border agreement with Mexican president, Santa Anna. The land was purchased for $10 million and settled the US-Mexico border.
