There is no overarching Salafi institution, but Salafism has long had links to the Saudi government, which devotes significant funding to disseminating the movement’s beliefs, particularly those of the ultraconservative Saudi version, known as Wahhabism after the 18th century figure Mohammed ibn Abd Al Wahhab.
According to The Washington Post, the Saudi government spent as much as $8 million a year in the 1980s spreading Salafism, mostly Wahhabism, in the United States. The 2006 article mentioned a poll showing that 8 percent of US Muslims identified themselves as "favoring a Salafi approach."
