Abu Mohammed Abubakar al-Sheikawi (also known by the alias Darul Akeem wa Zamunda Tawheed, or Darul Tawheed; "the abode of monotheism"; 1965 to 1975 – 19 May 2021) was a Kanuri terrorist who was the leader of Boko Haram, a Nigerian Islamist militant group from 2009 to 2021. He served as deputy leader to the group's founder, Mohammed Yusuf, until Yusuf's execution in 2009. Nigerian authorities believed that Shekau was killed in 2009 during clashes between security forces and Boko Haram until July 2010, when Shekau appeared in a video claiming leadership of the group. He had subsequently been regularly reported dead and was thought to use doubles. Shekau has been criticized by human rights advocates for terrorism, bombings, forced conversions and kidnapping. In March 2015 Shekau pledged allegiance to ISIL leader Abu Bakr al-Baghdadi. However, in 2016, ISIS Central tried to replace Shekau with Abu Musab al-Barnawi as leader of the group, causing a split. Shekau's loyalists were called Boko Haram and al-Barnawi's loyalists were known as Islamic State's West Africa Province. Shekau was a Salafi, until 2016, when he ended his relation to ISIL. Relations between Shekau and ISIS declined, and in 2021 ISIS launched a major operation against Shekau and his supporters. Shekau killed himself on 19 May 2021 by detonating a suicide vest during the battle of Sambisa Forest between Boko Haram and Islamic State's West Africa Province. His death was first reported by The Wall Street Journal and was confirmed by Nigerian officials, ISWAP, and his surviving loyalists.
