1st Century BCE-13th Century: Terrorism in the Pre-Modern World:
The history of terrorism is as old as humans' willingness to use violence to affect politics. The Sicarii were a first century Jewish group who murdered enemies and collaborators in their campaign to oust their Roman rulers from Judea.
Zealots and assassins were not, however, really terrorists in the modern sense. Terrorism is best thought of as a modern phenomenon. Its characteristics flow from the international system of nation-states, and its success depends on the existence of a mass media to create an aura of terror among many people.
1793: The Origins of Modern Terrorism:
The word terrorism comes from the Reign of Terror instigated by Maxmilien Robespierre in 1793, following the French revolution. Robespierre, one of twelve heads of the new state, had enemies of the revolution killed, and installed a dictatorship to stabilize the country. He justified his methods as necessary in the transformation of the monarchy to a liberal democracy:
Subdue by terror the enemies of liberty, and you will be right, as founders of the Republic.
Robespierre's sentiment laid the foundations for modern terrorists, who believe violence will usher in a better system. For example, the 19th century Narodnaya Volya hoped to end Tsarist rule in Russia.
But the characterization of terrorism as a state action faded, while the idea of terrorism as an attack against an existing political order became more prominent.

1950s: The Rise of Non-State Terrorism:
The rise of guerrilla tactics by non-state actors in the last half of the twentieth century was due to several factors.These included the flowering of ethnic nationalism (e.g. Irish, Basque, Zionist), anti-colonial sentiments in the vast British, French and other empires, and new ideologies such as communism.
Terrorist groups with a nationalist agenda have formed in every part of the world. For example, the Irish Republican Army grew from the quest by Irish Catholics to form an independent republic, rather than being part of Great Britain.
Similarly, the Kurds, a distinct ethnic and linguistic group in Turkey, Syria, Iran and Iraq, have sought national autonomy since the beginning of the 20th Century. The Kurdistan Worker's Party(PKK), formed in the 1970s, uses terrorist tactics to announce its goal of a Kurdish state. The Sri Lankan Liberation Tigers of Tamil Eelam are members of the ethnic Tamil minority. They use suicide bombing and other lethal tactics to wage a battle for independence against the Sinhalese majority government.
1970s: Terrorism Turns International:
International terrorism became a prominent issue in the late 1960s, when hijacking became a favored tactic. In 1968, the Popular Front for the Liberation of Palestine hijacked an an El Al Flight. Twenty years later, the bombing of a Pan Am flight over Lockerbie, Scotland, shocked the world.
The era also gave us our contemporary sense of terrorism as highly theatrical, symbolic acts of violence by organized groups with specific political grievances.
The bloody events at the 1972 Munich Olympics were politically motivated. Black September,a Palestinian group, kidnapped and killed Israeli athletes preparing to compete.Black September's political goal was negotiating the release of Palestinian prisoners. They used spectacular tactics to bring international attention to their national cause.
Munich radically changed the United States' handling of terrorism: "The terms counterterrorism and international terrorism formally entered the Washington political lexicon," according to counterterrorism expert Timothy Naftali.
Terrorists also took advantage of the black market in Soviet-produced light weaponry, such as AK-47 assault rifles created in the wake of the Soviet Union's 1989 collapse. Most terrorist groups justified violence with a deep belief in the necessity and justice of their cause.
Terrorism in the United States also emerged. Groups such as the Weathermen grew out of the non-violent group Students for a Democratic Society. They turned to violent tactics, from rioting to setting off bombs, to protest the Vietnam War.

1990s: The Twenty First Century: Religious Terrorism and Beyond
Religiously motivated terrorism is considered the most alarming terrorist threat today. Groups that justify their violence on Islamic grounds- Al Qaeda, Hamas, Hezbollah—come to mind first. But Christianity, Judaism, Hinduism and other religions have given rise to their own forms of militant extremism.
In the view of religion scholar Karen Armstrong this turn represents terrorists' departure from any real religious precepts. Muhammad Atta, the architect of the 9/11 attacks, and "the Egyptian hijacker who was driving the first plane, was a near alcoholic and was drinking vodka before he boarded the aircraft." Alcohol would be strictly off limits for a highly observant Muslim.
Atta, and perhaps many others, are not simply orthodox believers turned violent, but rather violent extremists who manipulate religious concepts for their own purposes.
