Yemeni-American cleric Anwar al-Awlaki, the leading English-language propagandist for al-Qa`ida, was killed in an American drone strike in 2011. But his influence has lived on into the Islamic State era, enhanced by his status as a martyr for Islam in the eyes of his admirers. His massive internet presence has turned up as a factor in several attacks since his death, including most recently the San Bernardino shootings and the Orlando nightclub attack as well as a significant number of terrorism cases on both sides of the Atlantic. Despite his long association with al-Qa`ida and that network’s rivalry with the upstart Islamic State, al-Awlaki has been embraced by the Islamic State and its followers, and he continues to inspire terrorism from beyond the grave.
