what is a revolution?
REBELLION OF MAJOR SCALE!
A revolution is a massive rebellion or protest against people in power and/or attempting to overthrow them.
In the American Revolutionary War, the "government tried to enforce colonial taxation", which really rubbed the colonists the wrong way and they "boycotted many British goods" as a result. There was an all out war later, which all 13 colonies took part in.
Now for the Pentrich Revolution, 50 people banded together and grew "over 300 strong" on their march to London due to "unemployment, poor working conditions, and low wages". They gathered "weapons and men" along the way, hoping to overthrow the government.
