It is a country whose seat was Venice and spread to Croatia, Montenegro, Slovenia, Greece, and Italy(only to parts of these countries, not the whole territory).

They achieved great wealth during the Crusades, transported the European army, and thus earned huge money. The contingent of their army also took part in those campaigns, so they gained enormous wealth.
