Answer:
ISIS is a jihadist terrorist militia. It controlled territory where more than ten million people lived, in Iraq and Syria. However, the terrorist movement is also active in other parts of the world, including Libya, Nigeria and Southeast Asia. It is known for its well-funded propaganda on websites and social media, with videos of beheadings of soldiers, civilians, journalists and aid workers, as well as the deliberate destruction of cultural heritage.
The group appears to have been established in the early years of the Iraq war, while developing ties with al Qaeda. Then, it separated from Al Qaeda to form its own organization, with the aim of establishing an Islamic caliphate in the territories that at some point belonged to that religion. That is, from Spain to the Middle East.
