How did enslaved people spread the african culture?

Enslaved Africans kept their culture intact when brought over, they passed it down through generations. Once they were freed, they shared it with others.

The transcontinental railroad provided a means of fast transportation. it cut a 6 month trip into 6 days, created jobs for many people and encouraged immigration. the homestead act played a huge role in western expansion; it allowed settlers to begin a fresh start, and gave them land in exchange for their residence for up to five years and a small fee.
