The Constitution is often hailed as a marvel of 
brevity and of clarity. It was, however, written in the 18th century, and many 
of the ideas, concepts, words, phrases, and euphemisms seem odd to us today, if 
not down right foreign. Some of the more obscure words are defined in The Glossary.
But what of the Constitution itself? What does it mean? What does each 
article, each section, say?
This page is like a synopsis or summary of the Constitution, article by 
article, amendment by amendment. This should not be taken as a substitute for 
the Constitution, but more like a study guide.
The Preamble to the Constitution has no 
force in law; instead, it establishes the “Why” of the Constitution. Why is 
this document in existence? It reflects the desires of the Framers to improve on the government they 
currently had (to be “more perfect” than the Articles 
of Confederation), to ensure that that government would be just, and would 
protect its citizens from internal strife and from attack from the outside. It 
would be of benefit to the people, rather than to its detriment. And, perhaps 
as importantly, it intended to do the same for the future generations of 
Americans. A more extensive exploration of the Preamble is also available.
Article 1 establishes the first of the three branches of the government, the 
Legislature. Section 1 establishes the name of 
the Legislature to be The Congress, a bicameral, or two-part, body.
Section 2 defines the House of 
Representatives, known as the lower house of Congress. It establishes a few 
minimum requirements, like a 25-year-old age limit, and establishes that the 
people themselves will elect the members for two years each. The members of the 
House are divided among the states proportionally, or according to size, giving 
more populous states more representatives in the House. The leader of the House 
is the Speaker of the House, chosen by the members.
Section 3 defines the upper house of 
Congress, the Senate. Again, it establishes some minimum requirements, such as 
a 30-year-old age limit. Senators were originally appointed by the legislatures 
of the individual states, though this later changed. They serve for six years 
each. Each state has equal suffrage in the Senate, meaning that each state has 
the exact same number of Senators, two each, regardless of the population. This 
Section introduces the Vice-President, who is the leader of the Senate (called 
the President of the Senate); the Vice-President does not vote unless there is 
a tie.
Section 4 says that each state may 
establish its own methods for electing members of the Congress, and mandates, 
or requires, that Congress must meet at least once per year.
Section 5 says that Congress must have a 
minimum number of members present in order to meet, and that it may set fines 
for members who do not show up. It says that members may be expelled, that each 
house must keep a journal to record proceedings and votes, and that neither 
house can adjourn without the permission of the other.
Section 6 establishes that members of 
Congress will be paid, that they cannot be detained while traveling to and from 
Congress, that they cannot hold any other office in the government while in the 
Congress.
Section 7 details how bills become law. 
First, any bill for raising money (such as by taxes or fees) must start out in 
the House. All bills must pass both houses of Congress in the exact same form. 
Bills that pass both houses are sent to the President. He can either sign the 
bill, in which case it becomes law, or he can veto it. In the case of a veto, 
the bill is sent back to Congress, and if both houses pass it by a two-thirds 
majority, the bill becomes law over the President’s veto. This is known as 
overriding a veto.
There are a couple more options for the President. First, if he neither 
vetoes a bill nor signs it, it becomes a law without his signature after 10 
days. The second option is called a pocket veto. It occurs if Congress sends 
the bill to the President and they then adjourn. If the President does not sign 
the bill within 10 days, it does not become law.
Section 8 lists specific powers of 
Congress, including the power to establish and maintain an army and navy, to 
establish post offices, to create courts, to regulate commerce between the 
states, to declare war, and to raise money. It also includes a clause known as 
the Elastic Clause which allows it to pass any law necessary for the carrying 
out of the previously listed powers.
Section 9 places certain limits on 
Congress. Certain legal items, such as suspension of habeas corpus, bills of 
attainder, and ex post facto laws are prohibited. No law can give preference to 
one state over another; no money can be taken from the treasury except by duly 
passed law, and no title of nobility, such as Prince or Marquis, will ever be 
established by the government.
Section 10, finally, prohibits the states 
from several things. They cannot make their own money, or declare war, or do 
most of the other things prohibited Congress in Section 9. They cannot tax 
goods from other states, nor can they have navies.
Article 2 establishes the second of the three branches of government, the 
Executive. Section 1 establishes the office of 
the President and the Vice-President, and sets their terms to be four years. 
Presidents are elected by the Electoral 
College, whereby each state has one vote for each member of Congress. 
Originally, the President was the person with the most votes and the 
Vice-President was the person with the second most, though this is later 
changed. Certain minimum requirements are established again, such as a 35-year 
minimum age. Presidents must also be a natural-born citizen of the United States. The 
President is to be paid a salary, which cannot change, up or down, as long as 
he in is office.
Section 2 gives the President some 
important powers. He is commander-in-chief of the armed forces and of the 
militia (National Guard) of all the states; he has a Cabinet to aid him, and can pardon criminals. He makes treaties with other 
nations, and picks many of the judges and other members of the government (all 
with the approval of the Senate).
Section 3 establishes the duties of the 
President: to give a state of the union address, to make suggestions to 
Congress, to act as head of state by receiving ambassadors and other heads of 
state, and to be sure the laws of the United States are carried out.
Section 4 briefly discusses the removal of 
the President, called impeachment.
Article 3 establishes the last of the three branches of government, the 
Judiciary. Section 1 establishes the Supreme 
Court, the highest court in the United States. It also sets the terms of 
judges, of both the Supreme Court and lower courts: that they serve as long as 
they are on “good behavior,” which usually means for life (no Justice and only 
a few judges have ever been impeached). It also requires that judges shall be 
paid.
Section 2 sets the kinds of cases that may 
be heard by the federal judiciary, which cases the Supreme Court may hear first 
(called original jurisdiction), and that all other cases heard by the Supreme 
Court are by appeal. It also guarantees trial by jury in criminal court.
Section 3 defines, without any question, 
what the crime of treason is.
Article 4 concerns the states. 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.
Article 5 details the method of amending, or 
changing, the Constitution. Please see The Amendments 
Page for more information.
Article 6 concerns the United States itself. 
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.
Article 7 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.
The Amendments
The first ten amendments to the Constitution were all adopted at the same 
time and are collectively known as the Bill of 
Rights.
The 1st Amendment protects the people’s right 
to practice religion, to speak freely, to 
assemble (meet), to address (petition) the government, and of the press to 
publish.
The 2nd Amendment protects the right to own 
guns. There is debate whether this is a right 
that protects the state, or a right that protects individuals.
The 3rd Amendment guarantees that the army 
cannot force homeowners to give them room and board.
The 4th Amendment protects the people from the 
government improperly taking property, papers, or people, without a valid 
warrant based on probable cause (good reason).
The 5th Amendment protects people from being 
held for committing a crime unless they are properly indicted, that they may 
not be tried twice for the same crime, that you need not be forced to testify 
against yourself, and from property being taken without just compensation. It 
also contains due process guarantees.
The 6th Amendment guarantees a speedy trial, 
an impartial jury, that the accused can confront witnesses against them, and 
that the accused must be allowed to have a lawyer.
The 7th Amendment guarantees a jury trial in 
federal civil court cases. This type of case is normally no longer heard in 
federal court.
The 8th Amendment guarantees that punishments 
will be fair, and not cruel, and that extraordinarily large fines will not be 
set.
The 9th Amendment is simply a statement that 
other rights aside from those listed may exist, and just because they are not 
listed doesn’t mean they can be violated.
The 10th Amendment is the subject of some 
debate, but essentially it states that any power not granted to the federal 
government belongs to the states or to the people. See the Federalism Topic Page for more information.
The 11th Amendment more clearly defines the 
original jurisdiction of the Supreme Court concerning a suit brought against a 
state by a citizen of another state.
The 12th Amendment redefines how the 
President and Vice-President are chosen by the Electoral College, making the 
two positions cooperative, rather than first and second highest vote-getters. 
It also ensures that anyone who becomes Vice-President must be eligible to 
become President.
The 13th Amendment abolished slavery in the entire United States.
The 14th Amendment ensured that all citizens 
of all states enjoyed not only rights on the federal level, but on the state 
level, too. It removed the three-fifths counting of slaves in the census. It 
ensured that the United States would not pay the debts of rebellious states. It 
also had several measures designed to ensure the loyalty of legislators who 
participated on the Confederate side of the Civil War.
The 15th Amendment ensures that race cannot 
be used as a criteria for voting.
The 16th Amendment authorizes the United 
States to collect income tax without regard to the population of the 
states.
The 17th Amendment shifted the choosing of 
Senators from the state legislatures to the people of the states.
The 18th Amendment abolished the sale or 
manufacture of alcohol in the United States. This amendment was later repealed 
(erased).
The 19th Amendment ensures that gender cannot 
be used as a criteria for voting.
The 20th Amendment set new start dates for 
the terms of the Congress and the President, and clarifies how the deaths of 
Presidents before swearing-in would be handled.
The 21st Amendment repealed the 18th 
Amendment.
The 22nd Amendment set a limit on the number 
of times a President could be elected – two four-year terms. It has one 
exception for a Vice-President who assumes the Presidency after the death or 
removal of the President, establishing the maximum term of any President to 10 
years.
The 23rd Amendment grants the District of 
Columbia (Washington D.C.) the right to three electors in Presidential 
elections.
The 24th Amendment ensured that no tax could 
be charged to vote for any federal office.
The 25th Amendment clarifies even further the 
line of succession to the Presidency, and 
establishes rules for a President who becomes unable to perform his duties 
while in office.
The 26th Amendment ensures that any person 18 
or over may vote.
The 27th Amendment requires that any law that 
increased the pay of legislators may not take effect until after an 
election.
