The history of the United States was preceded by the arrival of Native Americans in North America around 15,000 BC. Numerous indigenous cultures formed, and many disappeared in the 16th century. The arrival of Christopher Columbus in 1492 started the European colonization of the Americas. Most colonies were formed after 1600, and the United States was the first nation whose most distant origins are fully recorded. By the 1760s, the thirteen British colonies contained 2.5 million people and were established along the Atlantic Coast east of the Appalachian Mountains. After defeating France, the British government imposed a series of taxes, including the Stamp Act of 1765, rejecting the colonists' constitutional argument that new taxes needed their approval. Resistance to these taxes, especially the Boston Tea Party in 1773, led to Parliament issuing punitive laws designed to end self-government. Armed conflict began in Massachusetts in 1775.

In the 1870s, many activists in the United States were frustrated by the decision of President Ulysses S.

There were, nonetheless, some slaves in most free states up to the 1840 census, and the Fugitive Slave Act of 1850 specifically stated that a slave did not become free by entering a free state.

The temperance movement is a social movement against the consumption of alcoholic beverages. Participants in the movement typically criticize alcohol intoxication or promote complete abstinence from alcohol (teetotalism), and its leaders emphasize alcohol's negative effects on people's health, personalities and family lives. Typically the movement promotes alcohol education and it also demands the passage of new laws against the sale of alcohol, either regulations on the availability of alcohol, or the complete prohibition of it. During the 19th and early 20th centuries, the temperance movement became prominent in many countries, particularly in English-speaking and Scandinavian ones, and it eventually led to national prohibitions in Canada, in Norway and in the United States, as well as provincial prohibition in India. A number of temperance organizations exist that promote temperance and teetotalism as a virtue.
