September 18 1793:

George Washington lays the cornerstone to the United States Capitol building,
the home of the legislative branch of American government.
The building would take nearly a century to complete, as architects came and went,
the British set fire to it and it was called into use during the Civil War.
Today, the Capitol building, with its famous cast-iron dome and important collection of American art, is part of the Capitol Complex,
which includes six Congressional office buildings and three Library of Congress buildings,
all developed in the 19th and 20th centuries.

concurrent with U.S. troop withdrawals and was calculated to quell antiwar protests by students returning to college campuses after the summer.

22 September 1980: Iran-Iraq War

Long-standing border disputes and political turmoil in Iran prompt Iraqi President Saddam Hussein to launch an invasion of Iran’s oil-producing province of Khuzestan. After initial advances, the Iraqi offence was repulsed. In 1982, Iraq voluntarily withdrew and sought a peace agreement, but the Ayatollah Khomeini renewed fighting. Stalemates and the deaths of thousands of young Iranian conscripts in Iraq followed. Population centres in both countries were bombed, and Iraq employed the use of chemical weapons. In the Persian Gulf, a tanker war curtailed shipping and increased oil prices. In 1988, Iran agreed to a cease-fire.
