• Introduction (this page)
• Part 1: 1880-2000
• Part 2: 2001-2010
• Part 3: 2011-present

The above links provide, in three parts, a listing of selected terrorist attacks worldwide from 1880 to the present. It includes events of the following types: terrorist attacks resulting in 20 or more fatalties and/or 200 or more injuries; attacks otherwise of special political significance, such as assassinations; significant attacks involving unconventional weapons; and some non-terrorist criminal acts of methodological relevance.

These listings are incomplete. Incidents with 20-100 fatalities are relatively complete from 1950-2000 but are known incomplete for other periods. Ambiguities in the definition of terrorism are also an acknowledged issue. Data sets on this site prefer a definition of terrorism, in brief, as politically-motivated violence by sub-national actors. Domestic violence during civil wars is a prime example of ambiguity, and these listings are incomplete in such cases, particularly for some developing nations. Several cases of international state-sponsored terrorism are included, but in line with convention actions by governments within their territory, or actions by military forces, are not. Attacks against combatants are not automatically excluded, as the relevant criteria is whether the attacker is recognized as a terrorist by international law. Multiple coordinated attacks on a single day are counted as a single incident. Counts of fatalities and injuries include both victims and attackers. Several accident cases are included for the record as they have been erroneously identified as terrorist attacks by some sources. Accidental and criminal incidents (as opposed to terrorist incidents) are identified in the descriptions accordingly.

Summary data for the above listings (note: listings are incomplete):

• 642 incidents listed (including accidental and criminal), 39,688 fatalities and 88,703 injuries
• 612 terrorist incidents listed, total 36,029 fatalities and 84,753 injuries
