10927960518Republican MotherhoodPredominant conception of women's roles before, during and after the American Revolution: Though this idea emphasized the separation of women's and men's roles, it did weight heavily the influence of the mother on the family and advocated for this influence to be taken seriously.1
10927960519Legislative BranchThe branch of government tasked with writing laws.2
10927960520Judicial BranchThe branch of government tasked with interpreting/reviewing laws.3
10927960521Executive BranchThe branch of government tasked with enforcing laws.4
10927960522The Articles of ConfederationAn agreement among all thirteen original states in the United States of America that served as its first constitution. Drafted by a committee appointed by the Second Continental Congress, ratified in late 1777. Later replaced by the Constitution of the United States of America.5
10927960523Constitutional ConventionTook place from May 25 to September 17, 1787, in Philadelphia, Pennsylvania. Although the Convention was intended to revise the Articles of Confederation, the intention from the outset of many of its proponents, chief among them James Madison and Alexander Hamilton, was to create a new government rather than fix the existing one.6
10927960524Federalisma system of government in which entities such as states or provinces share power with a national government.7
10927960525Separation of PowersInspired by Montesquieu in The Spirit of the Laws, the idea of a constitutional government with three separate branches of government. Each of the three branches would have defined abilities to check the powers of the other branches.8

10927960529Bill of Rightsthe collective name for the first ten amendments to the United States Constitution. 17841. These amendments add to the Constitution specific guarantees of personal freedoms and rights, clear limitations on the government's power in judicial and other proceedings, and explicit declarations that all powers not specifically delegated to Congress by the Constitution are reserved for the states or the people.12
10927960530Democratic-Republican Partyformed by Thomas Jefferson and others who believed in an agrarian-based, decentralized,democratic government. The party was established to oppose the Federalists who had supported and pushed through the ratification of the US Constitution.13
10927960532The Northwest Ordinancecreated the the first organized territory of the United States, from lands beyond the Appalachian Mountains, between British North America and the Great Lakes to the north and the Ohio River to the south.14
10927960533French Revolutiona period of far-reaching social and political upheaval in France that lasted from 1789 until 1799, and was partially carried forward by Napoleon during the later expansion of the French Empire. The Revolution overthrew the monarchy, established a republic.15
10927960534Popular Sovereigntythe principle that the authority of a state and its government is created and sustained by the consent of its people, through their elected representatives (Rule by the People), who are the source of all political power.16
10927960536insurrectionRebellion against political authority.17
10927960537mercantilismThe economic theory that all parts of an economy should be coordinated for the good of the whole state; hence, that colonial economics should be subordinated for the benefit of an empire.18

10927960562ratificationThe confirmation or validation of an act (such as the constitution) by authoritative approval.22

10927960566annexTo make a smaller territory or political unit part of a larger one.24
10927960569bicameralReferring to a legislative body with two houses25
10927960571public debtThe debt of a government or nation to individual creditors, also called the national debt.26
10927960572cabinetThe body of official advisers to the head of a government; in the United States, it consists of the heads of the major executive departments.27
10927960573fiscalConcerning public finances-expenditures and revenues.28
10927960577impressmentTo force people or property into public service without choice.29
