When in 1789, George Washington became the first president of the United States, there was no permanent capital in which to house the government. During the Revolutionary War several different cities had served as the national capital. In addition, members of congress could not agree as to where this permanent capital should be located. Some officials wanted it in the north, others wanted it in the south. Each of the states hoped that the capital might lie within its own state lines. At last it was decided that the capital should occupy a section by itself, separate from any of the states. The place chosen was situated on the Potomac River. The land belonged originally to the state of Maryland, but Maryland agreed to the national government. The section was named the Washington. Work was begun on the new capital in 1791. in the year 1899 Congress occupied the new capital building at the same time the White House was opened as the home of all future presidents.
