The practice of terrorism has a long history. A universally acceptable definition of terrorism as a specific form of violence is difficult to evolve, but the idea is understood. The aim of this thesis is to investigate a study on terrorism, that is as old as humans' willingness to use violence to affect politics. The roots and practices of terrorism can be traced from the first century Sicarii Zealots , who were a Jewish group who murdered enemies and collaborators in their campaign to oust their Roman rulers from Judea. The Assassins, the next group to show recognizable characteristics of terrorism, also known as Hashhashin were a secretive Islamic sect active in Iran and Syria from the 11th century to the 13th century. The word terrorism and terrorist come from the Reign of Terror in 1793, following the French revolution. From the 19th century, radical political theories and improvements in weapons technology spurred the formation of small groups who effectively attacked nation-states. The primary goal of this thesis is to explore Google map facilities to build a map based application showing terrorism on an interactive timeline, including maps to show the areas and region where the terrorist attacks occur. To show terrorism in the past and present, the map is divided into four parts 1st century to 13th century, 14th century to 17th century, 19th century, 20th century and 21st century. The application can be accessed using any standard web browser and is implemented to make the application more responsive to the user.
