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.
