Definition:
Assassination is the term given to the murder of political or other well-known figures. It has been a stock ingredient in terrorists' arsenal since Narodnaya Volya (The People's Will), a late 18th century Russian group, assassinated Tsar Alexander II, a symbol of the feudal system they wished to revolutionize.
Notable assassinations by terrorist groups include the 1981 assassination of Egyptian President Anwar Sadat by Egyptian Islamic Jihad, to protest the Sadat's normalization of relations with Israel. In 1995, Israeli Prime Minister Yitzhak Rabin was assassinated by Yigal Amir, an extremist orthodox Jew who believed there was divine justification for killing a head of state.
