Understanding the U.S. Constitution: Foundations and Evolution

The U.S. Constitution, adopted in 1787, replaced the Articles of Confederation. It established a stronger federal government, balancing power between national and state authorities.

The Constitution's preamble sets out lofty goals: unity, justice, tranquility, defense, welfare, and liberty. It's a promise to the nation, encapsulating the Constitution's purpose.

The Constitution's first three articles establish three branches of government: Legislative, Executive, and Judicial. They lay the groundwork for checks and balances, ensuring no single branch becomes too powerful.

The first 10 amendments, known as the Bill of Rights, were ratified in 1791. They guarantee fundamental liberties like speech, religion, and due process, reflecting the nation's core values.

The Constitution can be amended, but it's intentionally difficult. An amendment requires a two-thirds majority in Congress and ratification by three-fourths of states, ensuring broad consensus for changes.

Federalism under the Constitution allows for a distribution of powers between national and state governments. This system is unique, with enumerated powers for the federal government and reserved powers for the states.

The Elastic Clause, or Necessary and Proper Clause, grants Congress the ability to pass laws needed to carry out its enumerated powers. This has allowed for adaptation over time.

The 27th Amendment, concerning congressional pay raises, was proposed in 1789 but wasn't ratified until 1992—over 200 years later!
