Colonial boycotts of british goods before the revolutionary war were effective because
1) reduced the profits of british merchants
2) lowered the prices of imported products
3) left the british troops short of supplies in the colonies
4) allowed the americans to start their own factories

The correct option is 1) Reduced the profits of British merchants

Explanation:

The Revolutionary War took place due to extreme tensions between the North American colonies and the government which was under the British crown. The conflict was turned into an international one with the involvement of France in favour of the locals.

Before the Revolutionary War, the colonists boycotted every product of the Britishers. As a result, the economy of Britain was highly affected and the profits of British merchants were greatly reduced.
