The United States government is composed of three major sections. It is based on the Constitution of the United States of America that was put into effect in May, 1789. The three parts of the US Government are the executive, legislative and judicial branches. Each branch works independently of the other two and each has its own responsibilities. This system is in place to ensure that no branch can carry more power than the other. This is called the separation of powers, which was written into the Constitution.
The executive branch is the branch that most Americans are familiar with. It includes the president of the United States, the vice-president, and the cabinet. The president is the leader of the country and is the commander in chief of the US military. The vice president is second in command, and will act as president if the president dies, resigns, or is removed from office. The cabinet acts as agents of the US President, and carry out the duties they are entrusted with. The legislative branch of government consists of the House of Representatives, and the Senate. Together they form the congress, which can levy and collect taxes, mint money, and establish federal courts. It can also declare war and raise and support the army, navy, and air force to protect the country.
The House of Representatives has four hundred and thirty five members and the Senate consists of one hundred senators, with two from each of the states. Any legislation, or new law must be approved by both the House of Representatives and the Senate. The judicial branch is entrusted to apply the laws created by the legislative branch of government. It has the power to create lower courts under the Supreme Court of the United States. It works closely with state courts, although they are separate.
