Trinoda necessitas

Trinoda necessitas is a Latin term used in Anglo-Saxon times: meaning threefold tax. Subjects of an Anglo-Saxon king were required to yield three services: repairing bridges, building fortifications, and serving in the fyrd (the militia). Rulers very rarely exempted subjects from the trinoda necessitas, because these services were the lifeblood of an Anglo-Saxon kingdom.
