Surprise predatory attacks directed against other communities or societies. The primary objective of raiding usually is to plunder and then to escape unharmed with the stolen goods. In some societies, the goal is also to kill men in the target community as well as kidnap women and children. Raiders are virtually always men. Raiding is a more organised form of aggression than feuding. Violent encounters are often the result of opportunistic meetings in the case of feuding. In contrast, raids are planned in advance. Another difference is that raids occur in a finite time period. They are rarely sustained activities like feuds.
