This document summarizes the revolutionary catechism written by Sergey Nechayev in 1869. It outlines 26 duties and principles for revolutionaries, including that they must be dedicated solely to revolution and destruction of the existing social order, show no mercy or sentimentality, and use all means necessary to intensify suffering of the people to drive them to revolt against the state. The revolutionary's only goal is total destruction of the state and existing social structures through an uprising of the oppressed masses.
