a cultural boundary is a boundary line that runs along differences in ethnicity, such as language and religion. An example of this is found within the country of Canada, where French is the official language of Quebec.

Some conceptes that terrorism include are
- The indiscriminate and random killing of persons, especially civilians and non-combatants,
- Assassinations,
- The emphasis on the surprise nature of attacks,
- The quest for shocking the community through media coverage,
- The existence of a self
-proclaimed political agenda or “cause” to justify those attacks.
The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets, they are collateral damage. And blowing up planes, trains, markets or buses is not the goal, those are just tactics. The real targets of terrorism are the rest of us: the billions of us who are not killed but are terrorized because of the killing. The real point of terrorism is not the act itself, but our reaction to the act.
State-sponsored terrorism is government support of violent non-state actors engaged in terrorism
The Piazza Fontana Bombing was one of the deadliest terrorist attacks in history. A bomb exploded at the headquarters of the National Agrarian Bank some 200m from the Duomo in Milan, Italy. The attack resulted in 17 fatalities with more than 88 wounded. The same afternoon, 3 more bombs were said to be planted in different cities around Italy. 2 of them exploded in Rome and Milan and the 3rd one was retrieved before detonation.
One quote i found very interesting was this one
"One man's terrorist is another man's freedom fighter"
