Incitement to commit an offense is an attempt to persuade another person, by whatever means, to commit an offense. There are many ways of doing this. Both rewards and punishments can provide the incentive to commit crimes. Someone can offer a reward for committing genocide, or they can try to blackmail a person. Incitement can be achieved by threats. A person can also try to get others to commit an offense by the use of argument and rhetoric. "Rabble rousing" is a common method of used to convince large groups of people act to in a particular way. Inflammatory speeches in political rallies have been used to prepare the way for genocide, or to whip crowds into states of frenzy in which killings may easily occur. The drafters of the genocide convention knew this all too well, and therefore included incitement to commit genocide as a listed crime in the 1948 Convention.
