Hello! I was wondering if somebody could help with this question...

- During the early eighteenth century the colonial assemblies had gained what two important powers, what were they?

According to Encarta Encyclopedia,

"In reality, the governors had to share their power with the American assemblies. The colonial legislatures copied some of the methods used by English politicians to boost Parliament's authority such as insisting on controlling taxes and on being consulted on appointments to public office."

During the early eighteenth century, the colonial assemblies in America gained two important powers. The first power was the authority to control taxes. This meant that the colonial assemblies had the ability to levy and collect taxes from the colonists, giving them a say in how the colony's finances were managed.

The second power that the colonial assemblies gained was the right to be consulted on appointments to public office. This meant that the governors of the colonies could not make appointments to important positions without first consulting and seeking the approval of the colonial assemblies. This gave the colonial assemblies a say in the governance of the colonies and helped to assert their authority alongside the governors.

To find this information, I used Encarta Encyclopedia and searched for "History of Colonial America." In the article, I found a section that discussed the powers of the colonial assemblies during that time period. The source provided a brief explanation of the two important powers gained by the colonial assemblies.
