Renowned as "men of action," the turians have a militaristic culture revolving around public service. Turians earned their place in galactic society after their actions in ending the Krogan Rebellions. They subsequently served as the peacekeeping arm of the Citadel Council and commanded the largest fleet in the Milky Way.
Turian society once relied on client species like the volus to build their economy and trade. In the Andromeda Initiative, the military training all turians undergo allows them to fill many vital civic and security roles, but many have also enrolled for entrepreneurial or diplomatic training to be better-rounded colonists.
Galactic events and their military doctrine have left lingering resentments between turians and some species. The turians were responsible for deploying the genophage against the krogan; and misunderstandings with humans led to the First Contact War, though humans and turians have since become cordial, if not close, allies.
