My answer begins in 1607. This is when the English settled at Jamestown, which became known as the first successful colony. English colonies tried to settle and Roanoke, but after a few weeks the people went missing. The picture below shows a man named John Smith. He is known for making the "No work No eat" policy. This event was important to our country because this allowed people to start living in the "new world".
LEXINGTON AND CONCORD
The second part to my answer is when the Revolutionary War started. The first two battles were Lexington and Concord. At Lexington somebody fired the first shot of the war. That shot today is known as " the shot heard around the world". This was important to us and our country because these two battles were what made people want independence from England.
