How many amendments does the US Constitution have? A guide to the founding document.

In his final speech as president, Barack Obama, speaking to a crowd in Chicago, said: "Our Constitution is a remarkable, beautiful gift; but it's really just a piece of parchment. It has no power on its own. We the people give it power."

His sentiment, that the founding documents of this country hold only as much weight as we allow for, forms the basis of constitutional democracies all around the world. The construction of a government is dependent on its citizens buying in, believing that the laws have legitimacy, and working to rewrite or abolish those that do not — a fight that continues in America.

How many amendments are there?

The Constitution of the United States has been amended 27 times.

The first 10 amendments are commonly referred to as the Bill of Rights, and the remaining 17 deal with everything from who can vote, to whether or not senators can give themselves a raise.

Back to the start: Here's when the US Constitution was written

Who is the chief justice of the United States now?

Right now, the Chief Justice of the United States is John G. Roberts.

Justice Roberts has served as Chief Justice of the Supreme Court since 2005, when he was nominated by then-President George W. Bush.

How long do Supreme Court justices serve for?

Supreme Court justices are appointed to serve a lifetime term, though it is not required that they serve until their end of life.

In the history of the court, justices have served for an average of 16 years, according to the court's official site, and a new court is added to the bench roughly every two years.

How many U.S. Senators are there?

There are 100 senators. As outlined in Section 3 of Article I of the U.S. Constitution, two senators are sent to the congress from each state.

The 100 figure is therefore not specifically designated — should there ever be more states added to the union, that number would increase, with two new senators added for each new state.

Which state has the most signers to the Constitution?

Pennsylvania.

There were 34 delegates to the Continental and Confederation Congress who signed the United States Constitution, eight of whom hailed from Pennsylvania.

Delegates from these remaining states also signed the founding document:

  • Connecticut

  • Delaware

  • Georgia

  • Maryland

  • Massachusetts

  • New Hampshire

  • New York

  • New Jersey

  • North Carolina

  • South Carolina

  • Virginia

Who has the power to declare war?

The Constitution of the United States grants Congress, and only Congress the power to declare war.

However, the President serves as Commander-in-Chief of the United States armed forces and can use military force without congressional approval prior.

Many of the military conflicts of recent memory have not been initiated by a formal declaration of war.
