Filstingpound or fulstingpound was an occasional duty paid by villeins in medieval England to the manor.
[1] It is thought by historians to be an insurance against corporal punishment or excessive fines.
Its etymology appears to be a compound of the obsolete English word "filsting", which means help or aid; and "pound", in the sense of being struck.
The duty was typically annual and received on All Hallows' Day.
It was a relatively advanced insurance scheme for the High Middle Ages.
