Answer 2

Answer:

What motivated early migration to North America was religious persecution in England.

The way for migrants to get there was to be hired as servants of colonial leaders.

Explanation:

The Colonies in North America originate from the founding of the city of New Plymonth (Massachussets) in 1620 by the "mayflower pilgrims", Puritans who fled England due to religious persecution and established a pact according to which the government and the laws would follow the will of the majority.

From NewPlymonth new nuclei emerged, linked to fishing, small-scale cultivation and trade. However religious intolerance led to migration to other regions and thus new colonies were founded: Rhode Island and Connecticut (1636) and New Hampshire (1638). In this region, generically termed "New England" the colonies thrived mainly on trade. One way for migrants to reach these colonies was to be hired as servants.
