Jama'at al-Tawhid wal-Jihad
Jama'at al-Tawhid wal-Jihad, abbreviated as JTJ or Jama'at, was a Salafi jihadist militant group. It was founded in Jordan in 1999, and was led by Jordanian national Abu Musab al-Zarqawi for the entirety of its existence. During the Iraqi insurgency (2003–11), the group became a decentralized network with foreign fighters with a considerable Iraqi membership.

Abu Musab al-Zarqawi, born Ahmad Fadeel al-Nazal al-Khalayleh, was a Jordanian jihadist who ran a terrorist training camp in Afghanistan. He became known after going to Iraq and being responsible for a series of bombings, beheadings, and attacks during the Iraq War, reportedly "turning an insurgency against US troops" in Iraq "into a Shia–Sunni civil war". He was sometimes known by his supporters as the "Sheikh of the slaughterers".
