What are some subtopics for events that led the 13 colonies from a newly independent nation to a transcontinental country?

The United States was not always a united nation. Before the United States became  what it is today, it had been just thirteen colonies. Those colonies transformed from a united  country into something more, a transcontinental nation, with the help of many events.Though  deaths and sacrifices were made in the process, it helped shape the transcontinental nation.  The thirteen colonies went from a new independent country to a transcontinental nation  because of the economic improvements, the War of 1812, and the westward expansion.   
Economic improvements helped the transformation into a transcontinental nation in a  big way. The ways were the use of the National Bank and the American System, as well as  the First Industrial Revolution.  The National Bank was proposed by, then Treasurer,  Alexander Hamilton. The National Bank would control government finances. It would also  "performed the basic banking functions of accepting deposits, issuing bank notes, making  loans and purchasing securities." (National Bank History). The American System is "consisted  of three mutually reinforcing parts: a tariff to protect and promote American industry; a  national bank to foster commerce; and federal subsidies for roads, canals, and other "internal  improvements" to develop profitable markets for agriculture." (Senate Historical Office). The  American System became a main focus in the Whig Party opposition against Andrew  Jackson. The First Industrial Revolution greatly helped the transformation. When Samuel  Slater brought his ideas from Britain the idea of the cotton mill was thought of and built in  Massachusetts.

jim crow law, in u.s. history, any of the laws in which racial was enforced, in the south between the finish of reconstruction in 1877 and the start of the social liberties development during the 1950s.

jim crow was the name of a minstrel routine( jump jim crow) performed starting in 1828 by its creator, thomas dartmouth ("daddy") rice, and by numerous imitators, including on-screen character joseph jefferson.

the term came to be a defamatory sobriquet for african americans and an assignment for their segregated life. the segregation rule was stretched out to parks, graveyards, theaters, and eateries with an end goal to keep any contact among blacks and whites as equivalents.
