What did the Townshend Acts (1767) primarily impose duties on?

The Townshend Acts, enacted in 1767 by the British Parliament, primarily imposed duties on tea, glass, paper, and other goods imported into the American colonies. The aim of these acts was to raise revenue to pay for the salaries of colonial governors and judges, which would make them more independent from colonial control. By targeting these specific materials, the British government sought to assert its right to tax the colonies and maintain economic control, leading to significant unrest among colonists who viewed the taxes as a violation of their rights. The inclusion of tea in particular was significant, as it played a central role in colonial life and later became a focal point of protest, culminating in events such as the Boston Tea Party.
