After Syria's crisis begins, the group's leader Abu Bakr al-Baghdadi sends operatives there to set up a Syrian subsidiary. Baghdadi follows in 2013, breaking with al Qaeda and renaming his group 'The Islamic State in Iraq and the Levant'.
In Syria, it massacres hundreds of members of the Sheitaat tribe. In Iraq, it slaughters thousands of Yazidis in Sinjar and forces more than 7,000 women and girls into sexual slavery.
In September, the United States builds a coalition against IS and starts air strikes to stop its momentum, helping the Syrian Kurdish YPG militia turn it back from Kobani on the border with Turkey.
