In response to the actions of the Patriot Colonist, the British Parliament responded by enacting the Boston Port Act, the Massachusetts Government Act, the Administration of Justice Act, the Quartering Act. The laws were retaliatory and intentionally designed to inflict undesirous conditions upon Massachusetts.

The Patriot Colonists, otherwise known or referred to as American Whigs, were colonies who rejected British Rule. They were thirteen of them. Their actions involved the destruction of 342 chests of tea in Boston, Massachusetts because the British Parliament had enacted the Tea Act, automatically conferring a monopoly status on British East India Company (BEIC) which sold tea in the colonies. The Tea Act prevented BEIC from sinking into bankruptcy. This may have been tolerated if there was nothing else, but the Act also added a small tax, an action which vexed the colonists and triggered what their action which became labelled by historians as the Boston Tea Party.

The "punishment" on Massachusetts backfired. It attracted the sympathy of other colonies and even the support of The Congress who pledged to support Massachusetts in case of attack from the Britons.
