Black Friday (), 13 August 2004, was the crackdown by the Maldivian National Security Service (NSS) — later Maldivian National Defence Force — on a peaceful protest in the capital city of Maldives, Malé. This unplanned and unorganized demonstration was the largest such protest in the country's history. Beginning on the evening of August 12, 2004, the demonstration grew and continued until it was forcefully ended on the afternoon of August 13, 2004. Protesters initially demanding the freeing of the pro-reformists arrested on the afternoon of August 12, 2004. As the protest continued to grow, people demanded the resignation of president Maumoon Abdul Gayoom, who had been in power since 1978.
