Answer:
The group "Sons of Liberty" emerged in the united states' colonies. They opposed the taxes levied by the British and advocated the rights of its people. Their constant revolt paved the way for the revolutionary war.
To maintain control over its colonies, Britain required finances to manage its forces. Subsequently, Britain levied unnecessary taxes in its colonies.
The major unwarranted tax was the Stamp Act which caused the major revolt from Sons of Liberty and hence, fuelled the revolutionary war.
