How did many colonist protest the taxes placed on british goods?

they did many things such as protest, have fights with the british and of course throw tea into the lake

using propaganda and effigies or i mean

The British (specifically the King) put taxes on the colonists because England had just fought in a war and needed to pay off their war debts. They created new taxes to get more money.

Among the many, many effects were those that led to the revolutionary war.

Patrick Henry spoke to the House of Burgesses. The Sons of Liberty was formed. Colonists boycotted British goods. The Stamp Act was passed.Take your pick ;)
