Why was it so difficult for the British to manage the colonies?

It was very difficult because the land was across the globe. For example, if the king made a new rule, they would only recieve new about it months later.

they united the colonies in their fight against the british.

after the senate and the house passed different bills and deadlock threatened, a compromise bill was worked out with the following provisions: (1) missouri was admitted as a slave state and maine (formerly part of massachusetts).
