Why did parliament start imposing heavy taxes on the colonies

The parliament started imposing heavy taxes on the colonies to pay British War Debts

Explanation:

After the battle of Seven Year' war, British expelled France. British faced huge war debts in order to fund the army and provide subsidies to its allies. British started to tax the people of its own country and this huge burden of taxes was not accepted by the people and they fell on streets and protested the crown. British felt that any further burden of taxes would annoy the people of home land and hence decided to burden the colonial people in America.

Before the seven year' war most of the American colonies contributed to the British Revenue but after the war, British started to burden them with heavy taxes which annoyed the American colonists. American colonists asked for representation in the parliament so that it would enable the crown to listen to their grievances but they were turned down. This annoyed the colonists drastically and they began to protest which paved way for the American independence.
