Title: Federal government of the United States
Content:  The federal government of the United States (U.S. federal government or U.S. government) is the national government of the United States, a federal republic in North America, composed of 50 states, a federal district (District of Columbia, where the government is based), five major self-governing territories and several island possessions. The federal government is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the U.S. Constitution in the Congress, the president and the federal courts, respectively. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court.
Title: Comparison of U.S. state and territory governments
Content:  In the United States, the government of each of the 50 states is structured in accordance with its individual constitution. In turn, each state constitution must be grounded in republican principles. Article IV, Section 4, Clause 1 of the United States Constitution tasks the federal government with assuring that each state's government is so organized. All state governments are modeled after the federal government and consist of three branches (although the three-branch structure is not Constitutionally required): executive, legislative, and judicial. All state governments are also organized as presidential systems where the governor is both head of government and head

The government is regulated by a system of checks and balances defined by the U.S. Constitution, which serves as the country's supreme legal document. The Constitution establishes the structure and responsibilities of the federal government and its relationship with the individual states. Article One protects the right to the writ of habeas corpus. The Constitution has been amended 27 times; the first ten amendments, which make up the Bill of Rights, and the Fourteenth Amendment form the central basis of Americans' individual rights. All laws and governmental 
Title: Politics of the United States
Content:  The United States is a constitutional federal republic, in which the president (the head of state and head of government), Congress, and judiciary share powers reserved to the national government, and the federal government shares sovereignty with the state governments. The executive branch is headed by the president and is independent of the legislature. Legislative power is vested in the two chambers of Congress: the Senate and the House of Representatives. The judicial branch (or judiciary), composed of the Supreme Court and lower federal courts, exercises judicial power. The judiciary's function is to interpret the United States Constitution and federal laws and regulations. This includes resolving disputes between the executive and legislative branches. The federal government's layout is explained in the Constitution. Two political parties, the Democratic Party and the Republican Party, have dominated American

The federal government exercises its supreme power not as a unitary entity, but instead via the three coordinate branches of the government (legislative, executive, and judicial), each of which has its own prescribed powers and limitations under the Constitution. In addition, the doctrine of separation of powers functions as a limitation on each branch of the federal government's exercise of sovereign power. One aspect of the American system of government is that, while the rest of the world now views the United States as one country, domestically American constitutional law recognizes a federation of state governments separate from (and 
Title: Central government
Content:  government of a federation. The United States is considered the first modern federation. After declaring independence from Britain, the U.S. adopted its first constitution, the Articles of Confederation in 1781. This was the first step towards federalism by establishing the confederal Congress. However, Congress was limited as to its ability to pursue economic, military, and judiciary reform. In 1787, a Constitutional Convention drafted the United States Constitution during the Philadelphia Convention. After the ratification of the Constitution by nine states in 1788, the U.S. was officially a federation, putting the U.S. in a unique position where the central government exists by the sufferance of the individual states rather than the reverse. Other states followed suit in establishing federal governments: Switzerland (1848); Canada (1867); Germany (1871 and again 1949); Brazil (1891); Australia (1901); Russia (1917); Austria (1920 and again 1945) and India (1947 and again 1950). Examples include: 
Title: Limited government
Content:  Limited government is closely associated with constitutions; the United States Constitution of 1789 and the French Constitution of 1793 were both enacted in an effort to reaffirm limited government, although in different ways. The U.S. Constitution achieved limited government through a separation of powers: "horizontal" separation of powers distributed power among branches of government (the legislature, the executive, and the judiciary, each of which provide a check on the powers of the other); "vertical" separation of powers (federalism) divided power between the federal government and the state government). James Madison, one of the authors of the Federalist Papers, noted that the Framers of the American Constitution sought to 
Title: State governments of the United States
Content:  State governments of the United States are institutional units exercising functions of government at a level below that of the federal government. Each state's government holds legislative, executive, and judicial authority over a defined geographic territory. The United States comprises 50 states: 9 of the Thirteen Colonies that were already part of the United States at the time the present Constitution took effect in 1789, 4 that ratified the constitution after its commencement, plus 37 that have been admitted since by Congress as authorized under Article IV, Section 3 of the Constitution.

Content:  adopted the United States Constitution, replacing the weak Confederation by establishing a comparatively strong national government structured as a federal republic, which included an elected executive, a national judiciary, and an elected bicameral Congress representing states in the Senate and the population in the House of Representatives. It is the world’s first federal democratic republic founded on the consent of the governed. Shortly after a Bill of Rights was ratified as the first ten amendments, guaranteeing fundamental rights used as justification for the revolution. Around 60,000 Loyalists migrated to other British territories, particularly to Canada, but the great majority remained in the United States.
Title: Mexico
Content:   The United Mexican States are a federation whose government is representative, democratic and republican based on a presidential system according to the 1917 Constitution. The constitution establishes three levels of government: the federal Union, the state governments and the municipal governments. According to the constitution, all constituent states of the federation must have a republican form of government composed of three branches: the executive, represented by a governor and an appointed cabinet, the legislative branch constituted by a unicameral congress and the judiciary, which will include a state Supreme Court of Justice. They also have their own civil and judicial codes. The federal legislature is the bicameral Congress of the Union, composed of the Senate of the Republic and the Chamber of Deputies. The Congress makes federal law, declares
