To ensure the museum's longevity, Robbins lobbied the national legislature (Congress) to absorb his museum into the Smithsonian Institution, a federal group of museums and research centers. The House of Representatives approved this plan in 1978 with backing from Representatives John Brademas, Lindy Boggs, Ron Dellums, the Congressional Black Caucus, and former Vice President Hubert Humphrey. The Smithsonian directors adopted the museum the next year and began plans to move the collection from the townhouses into a proper museum. In 1981, the museum was renamed the National Museum of African Art.
