The first president to live in the White House was John Adams, the second president of the United States. He moved into the residence in 1800, during his term, after it was completed in Philadelphia. The building, originally known as the Presidential Mansion, was designed by James Hoban and has since become an enduring symbol of the executive branch. Adams's tenure solidified the tradition of presidential residence, and the White House has since hosted every U.S. president. Over the years, it has also undergone numerous renovations, expanding its historical significance as a center for American governance.
