Which branch of government is established by Article I of the Constitution?

Article I of the Constitution specifically establishes the Legislative Branch of the government. This branch is responsible for making laws, which is a foundational function in the structure of American governance. The Legislative Branch is composed of two houses: the Senate and the House of Representatives. Each house has distinct roles and powers, which collectively contribute to the law-making process. By detailing the structures, powers, and responsibilities of Congress, Article I lays the groundwork for how legislation is proposed, debated, and enacted, establishing a system of checks and balances with the other branches of government. This is fundamental to the functioning of democracy in the United States, as it ensures that the power to create laws is vested in representatives elected by the people, promoting accountability and responsiveness in governance.
