On 29 June 2014, Sunni Islamist jihadists declared an Islamic State, a self-proclaimed caliphate straddling the Middle Eastern countries of Iraq and Syria with dominion over 10m people.

Since then Isis and the Islamic State have made headlines across the globe for the conflicts they have waged with Iraqi forces and Kurdish fighters, their propaganda videos and their brutal online execution videos. One year on, IBTimes UK looks back at the events surrounding Isis during their first year.
