A- the massacre of Jamestown colonists

Explanation:

When the first permanent English colony was established in Jamestown, Virginia, the English were hoping to be dealt with positively by the American Indians. Be that as it may, this was not at first the situation.  

The American Indians considered English to be as gatecrashers, taking into account that these American Indians have been living on this land for quite a long time. This is one motivation behind why the American Indians assaulted, as they felt that the colonists were attempting to take control over their territory.
