Which act required colonists to pay for th soldiers that had been sent to maintain order?

The act that required colonists to pay for the soldiers that had been sent to maintain order was the Stamp Act.

Explanation:

The Stamp Act was a tax that the British government introduced into the North American colonies in 1765 in order to pay the costs of maintaining a standing army after the French and Indian War. This stamp duty related to legal documents, permits, commercial contracts, newspapers, wills, pamphlets and playing cards.

This led to fierce protest in the colonies. Nine colonies participated in the Stamp Act Congress, which met in New York. They honored the principle: "No taxation without representation". The law was eventually repealed. In order to contribute to the colonies, in 1767 the parliament accepted a series of excise duties, proposed by Townshend, the so-called Townshend Acts. These were import duties on tea, paper, glass, lead and paintings.
