At its creation in 1789, the legislative branch was the most innovative.
Rule by kings and emperors was an old style of government, and the legislature in many ways represented the new. Almost certainly, the founders intended Congress to have more important powers than the President and the Supreme Court. However, they placed many checks and balances on the legislature that have prevented absolute power in the hands of one branch. Founders controlled power not only by checks from the other branches, but by creating a bicameral, or two house, Congress — the Senate and the House of Representatives. The powers of Congress, then, are both constitutional and evolutionary.
The Constitution specifically grants Congress its most important power — the authority to make laws. A bill, or proposed law, only becomes a law after both the House of Representatives and the Senate have approved it in the same form. The two houses share other powers, many of which are listed in Article I, Section 8. These include the power to declare war, coin money, raise an army and navy, regulate commerce, establish rules of immigration and naturalization, and establish the federal courts and their jurisdictions.

The "elastic," or implied powers, clause gives Congress the authority to pass laws it deems "necessary and proper" to carry out its enumerated functions. Many Congressional powers that have evolved over the years are based on this important clause. Here are a couple.
The American Congress has more power than any legislature among the world's modern democracies. The parliaments of Europe are often "arena" legislatures that provide a forum for debate on policies proposed by a powerful prime minister or president. Only the American democracy enables its legislature with the critical role of setting the lawmaking agenda.
