History of Congress and the Capitol
This is the story of one of the world's great experiments in government by the people.
For more than two centuries, a new Congress has convened every two years following elections that determine all the seats in the House and one-third of those in the Senate. While the individuals change, the institution has endured-through civil and world wars, waves of immigration and great migrations, and continuous social and technological change.
The Congress we know today was created after the failure of a government under the Articles of Confederation, which left most powers to the states. In 1787, a convention of specially selected delegates proposed a new constitution that strengthened the national government and established a representative branch composed of a House and Senate.
From the beginning, the two bodies of Congress were meant to be different, yet interdependent. James Madison said they would be "as little connected with each other, as the nature of their common functions, and their common dependence on society, will admit." As a result, the House and Senate have different rules, traditions, and cultures. Yet in their shared responsibilities they function as the nation's single lawmaking body.
After the civil war, the country faced dramatic change as a landscape of farms and villages yielded to factories and sprawling cities. An abundance of labor and plentiful raw materials brought prosperity to many, and the image of the United States as a beacon of freedom and opportunity encouraged immigration from all parts of the world. Many workers, including immigrants, racial minorities, and children, however, often toiled long hours in dangerous conditions for little pay. By the turn of the century, reformers in Congress were pressing for new ways to make government more responsive to the needs of poor farmers, laborers, and urban dwellers.
By 1912, a nation of 48 states spanned the continent and was extending its influence overseas. With 10 new states entering the Union, the number of senators increased to 96 and the number of representatives to 435. As members of Congress moved into their first permanent office buildings, congressional service was becoming an increasingly demanding full-time occupation, a major change from the 19th century, when members seldom met for more than six months in each year.
