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.
Most Americans greeted the 20th century with optimism. The early decades saw economic growth and the expansion of democracy as women gained the vote. But two world wars, the Great Depression, and the nuclear age later tested such confidence.
