The rise and decline of Islamic State – how the jihadi group has conquered and lost territory in Iraq and Syria

The Islamic State (Isil) has asserted itself as one of the world’s most prominent terror groups since its beginnings in 2011, but it has suffered territorial losses over the last two years.

In January 2014, Isil captured the Syrian town of Raqqa and made it its de facto capital city. In June 2015, the group shocked the world when it seized Mosul, Iraq’s second largest city.
