Leges Henrici Primi

The Leges Henrici Primi or Laws of Henry I is a legal treatise, written in about 1115, that records the legal customs of medieval England in the reign of King Henry I of England. Although it is not an official document, it was written by someone apparently associated with the royal administration. It lists and explains the laws, and includes explanations of how to conduct legal proceedings. Although its title implies that these laws were issued by King Henry, it lists laws issued by earlier monarchs that were still in force in Henry's reign; the only law of Henry that is included is the coronation charter he issued at the start of his reign. It covers a diverse range of subjects, including ecclesiastical cases, treason, murder, theft, feuds, assessment of danegeld, and the amounts of judicial fines.
