A 1417 indenture between commissioners of John de Stanley (Lord of Man) and the 24 keys (principal men) of Mann, establishing procedures for the extradition of felons who flee the lordship and penalties for barons who harbour them. This document demonstrates the constitutional and legal framework of medieval Manx governance and the relationship between the Lord and the keys, relevant to understanding the island's institutional structure before the 1765 Revestment.
