The United States Constitution, written in 1787, created a federal government divided into three separate branches: the legislative, the executive, and the judicial. Each branch has its own distinct roles and responsibilities, ensuring that the work of governing the country is shared and clearly defined.
I. The Legislative Branch
Created by Article I of the Constitution
"All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives." — Article I, Section 1
The legislative branch is made up of Congress, which has two parts: the Senate and the House of Representatives.
Roles and Responsibilities:
Drafts and passes proposed laws
Approves the federal budget
Confirms or rejects the president's nominations for federal judges, Supreme Court justices, and heads of federal agencies

The House of Representatives can impeach federal officials, while the Senate holds impeachment trials and decides whether officials should be removed from office
The House of Representatives has 435 members, elected every two years, with representation based on each state's population. The Senate has 100 members, two from each state, elected every six years.

II. The Executive Branch
Created by Article II of the Constitution
"The executive Power shall be vested in a President of the United States of America. He shall hold his Office during the Term of four Years." — Article II, Section 1
The executive branch is responsible for carrying out and enforcing the laws passed by Congress. It is led by the president and includes the vice president, the cabinet, federal agencies, and the United States Armed Forces.

Cabinet members advise the president and lead their departments, such as State, Justice, and Treasury.
The executive branch oversees federal agencies such as the Central Intelligence Agency (CIA) and the Federal Bureau of Investigation (FBI)

III. The Judicial Branch
Created by Article III of the Constitution
"The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish." — Article III, Section 1
The judicial branch is responsible for interpreting the laws of the United States and ensuring they are applied fairly and consistently.
Roles and Responsibilities:

The Supreme Court is the highest court in the country. Below it are 13 Courts of Appeals, which review decisions made by lower courts, and 94 District Courts, where cases are first heard.
