Federal Government of The United States - History

History

The outline of the government of the United States is laid out in the Constitution. The government was formed in 1789, making the United States one of the world's first, if not the first, modern national constitutional republic.

The United States government is based on the principle of federalism, in which power is shared between the federal government and state governments. The details of American federalism, including what powers the federal government should have and how those powers can be exercised, have been debated ever since the adoption of the Constitution. Some make the case for expansive federal powers while others argue for a more limited role for the central government in relation to individuals, the states or other recognized entities.

Since the U.S. Civil War, the powers of the federal government have generally expanded greatly, although there have been periods since that time of legislative branch dominance (e.g., the decades immediately following the Civil War) or when states' rights proponents have succeeded in limiting federal power through legislative action, executive prerogative or by constitutional interpretation by the courts.

One of the theoretical pillars of the United States Constitution is the idea of "checks and balances" among the powers and responsibilities of the three branches of American government: the executive, the legislative and the judiciary. For example, while the legislative (Congress) has the power to create law, the executive (President) can veto any legislation — an act which, in turn, can be overridden by Congress. The President nominates judges to the nation's highest judiciary authority (Supreme Court), but those nominees must be approved by Congress. The Supreme Court, in its turn, has the power to invalidate as "unconstitutional" any law passed by the Congress. These and other examples are examined in more detail in the text below.
