What is the main conflict in Albion's Seed: Four British Folkways in America by David Hackett Fischer?

This tome is the first in a series of writings on the cultural history of the United States of America. The first concepts introduced are history and culture. The influence of the two is mutual: history creates but also influences culture. Here, as the title clearly shows, the English part of the nation's history is examined first. Everyone knows there was already a large continent with nations of tribal people who had different cultures. Centuries of visitation preceded anything like conquest. In the long run, the political policy of encouraging immigration combined with the need for room for burgeoning European populations and created the new America.
