The Pronoia (plural pronoiai; Greek: πρόνοια, meaning "care" or "forethought") was a system of granting dedicated streams of state income to individuals and institutions in the late Byzantine period of the Roman Empire. Beginning in the 11th century and continuing until the empire's conquest in the 15th century, the system differed in significant ways from European feudalism of the same period.
