Lüneburg Sate
The Lüneburg Sate () or Treaty of Lüneburg ("Sate" is Low German for settlement or treaty) was a territorial agreement between the territorial lord ("Landesherr"; i.e. the Guelphic Prince of Lüneburg) and the estates ("Landesstände") in the Principality of Lüneburg established in 1392. The treaty established a legal body whose function was to secure the rights of its members. To this end, a court, called the "Satekollegium", was formed. Membership of the rulers in this body was in return for the granting of a loan to the sum of 50,000 Mark löt in bonds and was tied to the  duration of the loan so that the "Lüneburg Sate" was in effect a mortgage contract. Besides the actual "Sate" letter, the treaty included three other letters, which described in detail the rights of the individual estates. The Lüneburg Sate entered into force in 1392, but ended de facto after the "Sate" War in 1396. It was formally rescinded in 1519.
