Judicia civitatis Londoniae

The Judicia civitatis Londoniae or Dooms of the City of London is a compilation of laws and customs from 930^[1] granted by Æthelstan^[2] that governed the City of London.^[3] It tried to get the peace or frith guilds, associations with a corporate responsibility for the good conduct of their members and their mutual liability,^[4] to unite^[5] although the Knighten Guilde was not included.^[6] Also involving the bishops and reeves of London,^[7] guild law came to be the law of the City of London.^[5]

Guild members were expected to be involved in almsgiving, caring for their sick, burial of the dead, and providing Masses for the souls of deceased members.^[8] There was also a monthly feast.^[2] As well as the religious and social practices there were also commercial aspects including insurance against losses and assistance in catching thieves.^[5] This foreshadowed later English Gild Merchants.^[5]
