An analogy is supplied by the carucata of the Danelagh, the eighth part of which was the bouata or " ox-land."
DANELAGH, the name given to those districts in the north and north-east of England which were settled by Danes and other Scandinavian invaders during the period of the Viking invasions.
The three chief divisions of the Danelagh were (1) the kingdom of Northumbria, (2) the kingdom of East Anglia, (3) the district of the Five (Danish) Boroughs - lands grouped round Leicester, Nottingham, Derby, Stamford and Lincoln, and forming a loose confederacy.
Stamford was the next to yield, soon followed by Nottingham, and in 920 there was a general submission on the part of the Danes and the reconquest of the Danelagh was now complete.
Though the independent occupation of the Danelagh by Viking invaders did not last for more than fifty years at the outside, the Danes left lasting marks of their presence in these territories.
