We were all Presidents of the US and we all made major impacts on the country, but each of us had different ways of doing so.
This is George Washington, he was the first president of the US. He set many precedents so future preidents learned how ro deal with issues that weren't written out in the Constitution. He also helped create what we know today as a very strong country, the United States of America.
This is John Adams, during his presidency he tried to resolve problems with France and Britain, his efforts then resulted in a war. Also, durimg his presidency the Alien and Sedition Acts were passed, which were to inprison people who spoke out against the government, cracked down on immigration, and were strict about deportation.
This is Thomas Jefferson, under his presidency was the acquirement of the Louisiana Purchase. This was big for the US because it gave us control of the Mississippi River and the Port of New Orleans, thus doubled the size of the US.
This is James Madison, during his presidency the War of 1812 was going on. His presidency brought us the Star-Spangeled Banner and our knowledge of impressment, although some people think that impressment was the main cause of the war it actually wasn not the main cause.
