Final answer:
The primary purpose of the British taxation acts during the mid-18th century was to raise revenue to pay off the British debt from the French and Indian War and assert greater control over the American colonies.
Step-by-step explanation:
The primary purpose of the British taxation acts during the mid-18th century, such as the Stamp Act and the Townshend Acts, was to raise revenue to pay off the British debt from the French and Indian War. These acts imposed direct taxes on the American colonists, such as taxes on imported goods like tea, glass, and paper. The British government also wanted to assert greater control over the colonies and ensure that the colonists contributed to paying down the debt.
