PL 11380-1506Palatinate of Lancaster: Chancery: Patent Rolls
The patent rolls in this series run from the first year of John of Gaunt's Palatinate (ducal years were used for dating 1377-1399) to 21 Henry VII. The series is incomplete, the main gaps being 1 Henry V to 10 Henry VI and 28 Henry VI to 1 Henry VII.
The rolls contain copies of documents which were issued under the Palatinate great seal, including grants, pardons, appointments, and leases. Since the royal writ did not run in the Palatinate the enrolments also include writs and mandates from the King for action in the county (for example to levy taxes); these become more numerous during the 15th century.
