Here’s a look at Islamic State in Iraq and Syria (ISIS).

Facts

Started as an al Qaeda splinter group.

Also known as Islamic State in Iraq and the Levant (ISIL) and Islamic State (IS).

ISIS aims to create an Islamic state called a caliphate across Iraq, Syria and beyond.

The group implements Sharia Law, rooted in eighth-century Islam, to establish a society that mirrors the region’s ancient past.

ISIS uses modern tools like social media to promote reactionary politics and religious fundamentalism. Fighters destroy holy sites and valuable antiquities as their leaders propagate a return to the early days of Islam.

ISIS’s revenue comes from oil production and smuggling, taxes, ransoms from kidnappings, selling stolen artifacts, extortion and controlling crops.

Leader

Since August 3, 2023, the leader of ISIS has been Abu Hafs al-Hashimi al-Qurayshi. Abu al-Husain al-Husaini al-Quraishi was the leader from November 2022 until his death in 2023.
