 Section 1 mandates that all states will honor the laws of all other states; this ensures, for example, that a couple married in Florida is also considered married by Arizona, or that someone convicted of a crime in Virginia is considered guilty by Wyoming.

Section 2 guarantees that citizens of one state be treated equally and fairly like all citizens of another. It also says that if a person accused of a crime in one state flees to another, they will be returned to the state they fled from. This section also has a clause dealing with fugitive slaves that no longer applies.

Section 3 concerns the admittance of new states and the control of federal lands.

Section 4 ensures a republican form of government (which, in this case, is synonymous with "representative democracy," and both of which are opposed to a monarchical or aristocratic scheme - the state derives its power from the people, not from a king or gentry) and guarantees that the federal government will protect the states against invasion and insurrection.

 First, it guarantees that the United States under the Constitution would assume all debts and contracts entered into by the United States under the Articles of Confederation.

It sets the Constitution and all laws and treaties of the United States to be the supreme law of the country.

Finally, it requires all officers of the United States and of the states to swear an oath of allegiance to the United States and the Constitution when taking office.

There are essentially two ways spelled out in the Constitution for how to propose an amendment. One has never been used.

The first method is for a bill to pass both houses of the legislature, by a two-thirds majority in each. Once the bill has passed both houses, it goes on to the states. This is the route taken by all current amendments. Because of some long outstanding amendments, such as the 27th, Congress will normally put a time limit (typically seven years) for the bill to be approved as an amendment (for example, see the 21st and 22nd).

The second method prescribed is for a Constitutional Convention to be called by two-thirds of the legislatures of the States, and for that Convention to propose one or more amendments. These amendments are then sent to the states to be approved by three-fourths of the legislatures or conventions. This route has never been taken, and there is discussion in political science circles about just how such a convention would be convened, and what kind of changes it would bring about.

Regardless of which of the two proposal routes is taken, the amendment must be ratified, or approved, by three-fourths of states. There are two ways to do this, too. The text of the amendment may specify whether the bill must be passed by the state legislatures or by a state convention. See the Ratification Convention Page for a discussion of the make up of a convention. Amendments are sent to the legislatures of the states by default. Only one amendment, the 21st, specified a convention. In any case, passage by the legislature or convention is by simple majority.

Article VII details the method for ratification, or acceptance, of the Constitution: of the original 13 states in the United States, nine had to accept the Constitution before it would officially go into effect.
