Timeline: Rise and Spread of the Islamic State

 

The Islamic State – also known as ISIS, ISIL, or Daesh – emerged from the remnants of al Qaeda in Iraq (AQI), a local offshoot of al Qaeda founded by Abu Musab al Zarqawi in 2004. It faded into obscurity for several years after the surge of U.S. troops to Iraq in 2007. But it began to reemerge in 2011. Over the next few years, it took advantage of growing instability in Iraq and Syria to carry out attacks and bolster its ranks.

The group changed its name to the Islamic State of Iraq and Syria (ISIS) in 2013. ISIS launched an offensive on Mosul and Tikrit in June 2014. On June 29, ISIS leader Abu Bakr al Baghdadi announced the formation of a caliphate stretching from Aleppo in Syria to Diyala in Iraq, and renamed the group the Islamic State.

A U.S.-led coalition began airstrikes against ISIS in Iraq on August 7, 2014, and expanded the campaign to Syria the following month. On October 15, the United States named the campaign “Operation Inherent Resolve.”

Over the next year, the United States conducted more than 8,000 airstrikes in Iraq and Syria. ISIS suffered key losses along Syria’s border with Turkey, and by the end of 2015, Iraqi forces had made progress in recapturing Ramadi. But in Syria, ISIS made gains near Aleppo, and still firmly held Raqqa and other strongholds.

In 2015, ISIS expanded into a network of affiliates in at least eight other countries. Its branches, supporters, and affiliates increasingly carried out attacks beyond the borders of its so-called caliphate. In October, ISIS’s Egypt affiliate bombed a Russian airplane, killing 224 people. On November 13, 130 people were killed and more than 300 injured in a series of coordinated attacks in Paris. The following is a timeline outlining key events through December 2015.
