The main reason behind Plymouth settlement is to achieve freedom of religion.

Explanation:

Some of the members of Separatist Church from England in 1620, September, during the era of King James I sailed towards Mayflower and ultimately landed in the Cape-Cod or Massachusetts. They finally decided to settle in the Plymouth Rock, the first permanent European settlement in New England, The Plymouth Colony.

The Separatist believed that the European Churches have somehow failed to perform the important works of Protestant Reformation, thus they left the Church and settled in Plymouth to regain freedom of religion and securing a better Utopian society there.
