Explanation:

The main reason that the alliance between Ousamequin’s people and the people of Plymouth ended was because Tens of thousands of English settlers arrived, overwhelming the region of New England.

This was evident when originally around 1629, the population of American settlers was barely one thousand around Massachusetts Bay Colony. But around 1670 the population has greatly increased to about seventy thousand people.

This population disrupts the activities of Ousamequin's people known as Wampanoag. They could not find enough rivers and an ideal place to farm and carry out fishing activities. Their forest which serves as a game continuously cuts down.

Hence, the alliance eventually came to an end coupled with the deaths of most leaders of the Wampanoag people including Ousamequin who had died.
