Hundreds of thousands of LGBT rights activists marched on Sunday, October 11, 2009 from the White House to the Capitol, demanding that President Barack Obama keep his promises to allow gays to serve openly in the military and work to end discrimination against LGBT people. Many organizers were outraged after the passage of California's Proposition 8, which overturned the right of gays to get married in that state, and over perceived slights by the Obama administration. Though there were no official crowd estimates, mainstream media outlets estimated as many as 200,000 people participated. Unlike the first national LGBT march in 1979 and others in 1987, 1993 and 2000 that included celebrity performances and drew as many as 500,000 people, the event was driven by grassroots efforts and was expected to be more low-key.
