Forming the smallest of the Islamic sects in Syria at 2%, the Twelver Shia play only a minor role in Syrian politics. In religious affairs, they look to Shia centers in Iraq, especially Karbala and Najaf, and to Iran. However, Iran's 1979 Islamic Revolution and Syria's alliance with Iran in its war with Iraq, have elevated the prestige of Syria's Shia minority. As hundreds of Iranian tourists began to visit Damascus each week, the Shia shrine of the tomb of Sayyida Zaynab, granddaughter of Muhammad, located in Al-Ghutah outside Damascus, became a major pilgrimage destination, replacing those areas no longer accessible in Iraq. Moreover, the Syrian Shia Twelvers have close links to the Shia Twelvers in Lebanon.
