Drupal became an open source project in 2001. The name Drupal represents an English rendering of the Dutch word druppel, which means "drop".

Interest in Drupal got a significant boost in 2003 when it helped build "Dean Space" for Howard Dean, one of the candidates in the U.S. Democratic Party's primary campaign for the 2004 U.S. presidential election.
