While some political goals may be achieved only through the use of terrorism, terrorists often kill or injure noncombatants or the innocent in order to maximize terror and to seek widespread publicity for their actions. Contemporary terrorism is often conceived in terms of war. While terrorism may be perpetrated by individuals against a state, states can enact policies of terrorism against their own citizens or subjects of another nation or country.Terrorism does not have a universally accepted definition. The term entered the Western popular and scholarly lexicon with reference to the excesses of the Jacobin regime in the aftermath of the French Revolution at the end of the 18th Century—though some have used the term to refer to secret societies of assassins in 1st-Century Palestine and 11th-Century Persia. In fact, through most of the early 19th Century, the term was mostly used with reference to state violence. In mainland Europe and Russia in the second half of the 19th and early 20th centuries, the terms terror and terrorism were mostly applied to substate left-wing anarchist and revolutionary movements. The concept had a brief realignment with the state during the Fascist/Nazi era in Germany and Italy, but it reverted back to being understood as a substate phenomenon during the second half of the 20th Century.Terrorism aims to create terror, a feeling of insecurity, and the idea that leaders can no longer protect those they lead. It leaves people stunned, and has an emotional impact that lives on through its political implications
