- Exkousseia
- Tax exemption (q.v.) on land, paroikoi (q.v.), ships, buildings, and animals that appears in the 10th century, taken advantage of by powerful landed magnates (the dynatoi [q.v.]). It is interpreted variously as the equivalent to immunity in the Latin West, and thus a complete tax exemption, or as an exemption only from certain taxes. In the 14th and 15th centuries the term appears to cover any tax exemption.
