Changes in the concept of Terrorism from past to present

''Terror is essentially a spectacle. By staging a frightening display of violence, terrorists capture our imagination and make us believe that we have fallen into medieval-like chaos. States then feel compelled to respond to this theater of terror with a show of security and massive displays of power, such as invading a foreign country or oppressing an entire population. This overreaction often jeopardizes our security more than the terrorists. ''
Yuval Noah Harrari

The evolution of the concept of terrorism from the past to the present has been a complex process shaped by the interaction of political, social, economic, and cultural factors. Terrorism has undergone changes in meaning over time, influenced by various contexts and societal transformations. However, the general evolution of terrorism can be examined through the following key points:
1. Classical Terrorism and Anti-Colonial Movements (19th Century - Early 20th Century): The history of terrorism begins with some anti-colonial struggles and revolutionary movements. The late 19th and early 20th centuries witnessed acts of terrorism typically employed by groups opposing the state, often striving for independence or political change.
2. Cold War Era (1947-1991): During the Cold War period, terrorism often emerged as part of ideological conflicts. Conflicts between communist and anti-communist groups were prevalent. Terrorism centered around national liberation struggles and revolutionary ideals in various regions.
3. International Terrorism (1970s - Present): In the 1970s, terrorism began to transcend national borders. International terrorist organizations, motivated by various ideologies, aimed to intervene in global political interactions or achieve specific objectives through violent acts. During this period, incidents like hijackings and embassy attacks were common.
4. Religiously Motivated Terrorism (1980s - Present): In subsequent years, another evolution of terrorism was the rise of religiously motivated motivations. Islamist terrorist organizations, particularly from the 1980s onward, orchestrated attacks based on religious ideologies. Notable examples include Al-Qaeda and the Taliban.
5. Impact of Technological Developments (2000s - Present): The rapid development of the internet and communication technologies allowed terrorist organizations to conduct propaganda, financing, and training more effectively. Additionally, new forms of threats such as cyberterrorism emerged. The evolution of terrorism continues to be influenced by political, social, and technological changes. This process will shape itself in response to international cooperation and alterations in security policies.
