Important events in history

Declaration of Independence


The U.S. formally ends their rule from Britain and becomes an independent Country.

Northwest Ordinance


The primary effect of the ordinance was the creation of the Northwest Territory, the first organized territory of the United States, from lands south of the Great Lakes, north and west of the Ohio River, and east of the Mississippi River.
-President George Washington signed the Northwest Ordinance of 1789 into law after the newly created U.S. Congress reaffirmed the Ordinance with slight modifications under the Constitution. The Ordinance purported to be not merely legislation that could later be amended by Congress, but rather "the following articles shall be considered as Articles of compact between the original States and the people and states in the said territory, and forever remain unalterable, unless by common consent...."[

Constitutional Convention


took place from May 25 to September 17, 1787, in Philadelphia, Pennsylvania, to address problems in governing the United States of America, which had been operating under the Articles of Confederation following independence from Great Britain.The result of the Convention was the creation of the United States Constitution, placing the Convention among the most significant events in the history of the United States.

Ratification of the Constitution

Alien and Sedition Acts Pass

-That it shall be lawful for the President of the United States, whenever he may deem it necessary (for the public safety, to order to be removed out of the territory thereof, any alien who mayor shall be in prison in pursuance of this act; and to cause to be arrested and sent out of the United States such of those aliens as shall have been ordered to depart therefrom and shall not have obtained a license as aforesaid, in all cases where, in the opinion of the President, the public safety requires a speedy removal.

Louisiana Purchase


the acquisition by the United States of America in 1803 of 828,000 square miles (2,140,000 km2) of France's claim to the territory of Louisiana. The U.S. paid 50 million francs ($11,250,000) plus cancellation of debts worth 18 million francs ($3,750,000), for a total sum of 15 million dollars (less than 3 cents per acre) for the Louisiana territory ($230 million in 2012 dollars, less than 42 cents per acre).[1][2][3]

The Louisiana territory encompassed all or part of 15 present U.S. states and two Canadian provinces. The land purchased contained all of present-day Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; parts of Minnesota that were west of the Mississippi River; most of North Dakota; most of South Dakota; northeastern New Mexico; northern Texas; the portions of Montana, Wyoming, and Colorado east of the Continental Divide; Louisiana west of the Mississippi River, including the city of New Orleans; and small portions of land that would eventually become part of the Canadian provinces of Alberta and Saskatchewan.

Admittance of the Florida Territory


Missouri Comprimise


It prohibited slavery in the former Louisiana Territory north of the parallel 36°30′ north except within the boundaries of the proposed state of Missouri. To balance the number of "slave states" and "free states," the northern region of what was then Massachusetts was admitted into the United States as a free state to become Maine.

Monroe Doctrine

Trail of Tears


the forced relocation and movement of Native American nations from southeastern parts of the United States following the Indian Removal Act of 1830. The removal included many members of the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations, among others in the United States, from their homelands to Indian Territory in eastern sections of the present-day state of Oklahoma.

Annexation of Texas


In 1845, the United States of America annexed the Republic of Texas and admitted it to the Union as the 28th state.

Treaty signed for Oregon


The United States signs a treaty with Britain that split the Oregon Territory in half at the 49th parallel.

Mexican Cession


The Mexican Cession of 1848 is a historical name in the United States for the region of the present day southwestern United States that Mexico ceded to the U.S. in the Treaty of Guadalupe Hidalgo in 1848, but had not been part of the areas east of the Rio Grande which had been claimed by the Republic, though the Texas Annexation resolution two years earlier had not specified Texas's southern and western boundary.

California Gold Rush

1849 - 1852

the news of gold brought some 300,000 people to California from the rest of the United States and abroad.[2] Of the 300,000, approximately half arrived by sea and half came from the east overland on the California Trail and the Gila River trail.

Gadsen Purchase


a 29,670-square-mile (76,800 km2) region of present-day southern Arizona and southwestern New Mexico that was purchased by the United States in a treaty signed by James Gadsden, the American ambassador to Mexico at the time, on December 30, 1853. It was then ratified, with changes, by the U.S. Senate on April 25, 1854 and signed by President Franklin Pierce, with final approval action taken by Mexico on June 8, 1854. The purchase was the last major territorial acquisition in the contiguous United States, adding a large area to the United States.
