The Hashashin were a group of Persian assassins who played a large role in the crusading age. Often born into the order, they had the reputation of being proficient killers as well as skilful spies. They're analogous to Christian military orders such as the Teutonic Order or the Livonian Order that exist in game. The company does not exist in EU4, instead it can only exist if it's imported from Crusader Kings II using the Europa Universalis 4 Save Converter.
National idea overview
The Hashashin's National Ideas make for a very interesting diplomatic-war style of gameplay, with great boosts not only to their spy offence, but also defence as well. In taking the Espionage idea group, this nation becomes one of - if not the - best at defeating an enemy from within in EU4, by either funding rebellions, or by ruining the reputation of the target nation and it's allies. Followed up by launching an invasion when the nation has been abandoned by their former allies, which would be further aided by the ability to infiltrate the administration of the enemy, letting the Hashashin see the position and movement of enemy armies and fleets. Completing the Defensive idea group is also a very good choice for this nation, as it means any invaders will suffer more attrition when attacking Hashashin lands.
