What is the main setting in the second half of the novel, Homegoing?

The book's second half is set in what might be described as the contemporary era in African-American history - specifically, the years following the Civil War (which is barely referred to in the book) - the late 1870's onward. Both the African and American narrative lines find themselves affected by events in the Industrial Revolution, which marked the division between the nineteenth and twentieth Centuries. The book concludes during the time of another transition between centuries - between the twentieth and twenty-first.
