This is a copy of a parchment roll surviving in the public record office. just 1/565
It is a record of crown pleas of the general Eyre of 1250, in the 34th. year of the reign of Henry III, taken in Norfolk. The Eyre was a periodic circuit of justices who had been commissioned by the king to hear all manner of civil & crown pleas such as felonies, protection or violation of liberties & privileges, murders etc. as well as auditing the royal revenues and inspecting county administration. The cases were presented by elected jurors representing hundreds (administrative subdivisions of the shire) and they had to answer the articles of the general Eyre - questions put to them by the justices on law & order in their area. The visits of the justices were infrequent so these cases may represent a span of a number of years.
This system of Justices in eyre was introduced in 1166 but was effectively abandoned in 1294.
