Between the 10th and the 19th centuries the hundreds of Norfolk and the boroughs of Norwich, King's Lynn, Thetford and Great Yarmouth were the administrative units of the English county of Norfolk. Each hundred had a separate council that met each month to rule on local judicial and taxation matters. The leet court boundaries were more fluid and transient than the hundred court boundaries. At the time of Domesday, the parishes of the hundreds of Brothercross and Gallow "were strangely intermixed".
