The answer is below

Explanation:

The three details in the early formation of the United States of America can be summarized into the following events:

1. American Revolutionary War: this occurred between 1775 to 1783. The eventual outcome led to the independence of the American colonies from Great Britain.

2. Constitutional Convention: this occurred between May 1787 to September of the same year. It led to the eventual ratification of the US Constitution. Thereby the US moved away from her initial use of the Articles of Confederation.

3. Louisiana Purchase: this occurred in 1803 under President Thomas Jefferson. Here the United States became more than double in terms of landmass after buying more than 500 million acres of land.
