Qutbism (also called Kotebism, Qutbiyya, or Qutbiyyah) is a strain of Sunni Islamist ideology and activism, based on the thought and writings of Sayyid Qutb, an Islamist and former leading member of the Muslim Brotherhood who was executed in 1966. It has been described as advancing the ideology of jihadism, i.e. propagating "offensive jihad," - waging jihad in conquest - or "armed jihad in the advance of Islam"

Qutbism has gained notoriety from what many^[who?] believe is its strong influence on jihadi extremists such as Osama bin Laden. According to observers, jihadi extremists “cite Sayyid Qutb repeatedly and consider themselves his intellectual descendants.”

Qutbists or Qutbiyyun, (singular Qutbee or Qutbi) are followers of these ideals but seldom if ever call themselves by these terms which originated from, and are mainly used by their opponents.

The main tenet of Qutbist ideology is that the Muslim community (or the Muslim community outside of a vanguard fighting to reestablish it) "has been extinct for a few centuries" having reverted to Godless ignorance (Jahiliyya), and must be reconquered for Islam.

Sayyid Qutb (Egyptian Arabic pronunciation: [ˈsæjjed ˈʔotˤb], Arabic: [ˈsæjjed ˈqotˤb]) (also Said, Syed, Seyyid, Sayid, or Sayed; Koteb, Qutub, Kotb, or Kutb) (Arabic: سيد قطب‎; October 9, 1906 – August 29, 1966) was an Egyptian author, educator, Islamist theorist, poet, and the leading member of the Egyptian Muslim Brotherhood in the 1950s and '60s.

Author of 24 books, including novels, literary arts’ critique and works on education, he is best known in the Muslim world for his work on what he believed to be the social and political role of Islam, particularly in his books Social Justice and Ma'alim fi-l-Tariq (Milestones). His magnum opus, Fi Zilal al-Qur'an (In the shade of the Qur'an), is a 30-volume commentary on the Qur'an.

During most of his life, Qutb's inner circle mainly consisted of influential politicians, intellectuals, poets and literary figures, both of his age and of the preceding generation. By the mid-1940s, many of his writings were officially among the curricula of schools, colleges and universities.
