Protests following the 2009 Iranian presidential election against the alleged victory of Iranian President Mahmoud Ahmadinejad and in support of opposition candidate Mir-Hossein Mousavi occurred in major cities in Iran and around the world starting June 13, 2009. The protests were given several titles by their proponents including Green Revolution, Green Wave or Sea of Green, reflecting presidential candidate Mousavi's campaign color, and also Persian Awakening. The events have also been nicknamed the "Twitter Revolution" because of the protesters' reliance on Twitter and other social-networking Internet sites to communicate with each other. Islamic politician Ata'ollah Mohajerani blasted the election as "the end of the Islamic Republic". In response to the protests, other groups rallied in Tehran to support Ahmadinejad.
Some called the controversial election results a coup. Widespread editorial analyses assert that the 2009 election marks the official end of the Islamic Republic and the beginning of the Abadgaran Regime. All three opposition candidates claimed that the votes were manipulated and the election was rigged, and candidates Mohsen Rezaee and Mousavi have lodged official complaints. Mousavi announced that he "won't surrender to this manipulation" before lodging an official appeal against the result to the Guardian Council on June 14.
Ayatollah Ali Khamenei declared the unprecedented voter turnout and coinciding religious holidays as a "divine assessment" and urged the nation to unite, but later ostensibly ordered an investigation into the claims of voting fraud and irregularities. Mousavi is not optimistic about his appeal, saying that many of the group's members "during the election were not impartial". Ahmadinejad called the election "completely free" and the outcome "a great victory" for Iran, dismissing the protests as little more than "passions after a soccer match".
Police and the Basij, a paramilitary group suppressed both peaceful demonstrating and rioting using batons, pepper spray, sticks and, in some cases, firearms. The Iranian government has confirmed the deaths of 36 people during the protests, while unconfirmed reports by supporters of Mousavi allege that there have been 72 deaths (twice as many) in the three months following the disputed election. Iranian authorities have closed universities in Tehran, blocked web sites, blocked cell phone transmissions and text messaging, and banned rallies.
