What is an indulgence? What is its context within what religion? Does it have any impact on the Reformation, if so what and how? Does it have any pre-Reformation significance? Do NOT restate any of the questions in your answer. I need this answer soon. Thank you!

An indulgence is the total or partial forgiveness of sin given by the Pope and received by God. In the 16th century, indulgences caused the Reformation because they were arbitrarily given and, in some cases, the indulgences were sold. Despite the market of indulgences were not new (since the 13th century this practice was made), it is in the 16th century that it intensifies.  

Explanation:

The role of the market of indulgences in the Reformation is because this practice leads to corruption. In the 16th century, the Catholic Church was the most influential and rich institution on Earth, but she was concerned only with wealth. The market of indulgences was only a part of this corruption. Martin Luther didn't accept this and fought against the sale of indulgences writing his 95 theses (what he didn't accept or considered right in the Church). The Reformation began when he fixed his theses at the door of the Cathedral of Wittenburg.

religion played a major role in the american revolution by offering a moral sanction for opposition to the british--an assurance to the average american that revolution was justified in the sight of god. the revolution strengthened millennialist strains in american.
