The war of 1812, faced the newly independent US and Britain and its colony of Canada.
Recall that the United States had already achieved its independence in the war of 1775-1783 where the 13 American colonies were revealed against the British.
The United States by popular acclamation approved in Congress declares war on June 18, 1812. The one now is not a direct war against the island of Great Britain, but a form of liberation against the British drowning, resulting in an attack on the Canadian border that threatened the security and independence of his young country. Because Canada belonged at that time to the British Empire. Curiously, the Native American Indians saw in the British a protection against the overwhelming American advance that was moving westward. This thought was fueled by the battle of Tippecanoe in 1811 where American troops destroyed an Indian settlement.
In Gitlow v. New York, 268 U.S. 652 (1925), the Supreme Court voted 7-2 to uphold the constitutionality of New York's Criminal Anarchy Statute of 1902, which prohibited advocating violent overthrow of the government.
The Constitution was drafted in 1787, after the American Revolution ended. What document preceded the Constitution in outlining the powers of the US government? the Declaration of Independence.
