These entries for Leiston indicate that it was a particularly thriving enterprise which generated great wealth for its former Saxon owner, Earl Eadric, and his Norman successor Robert Malet. In this context, 'soke' means a personal estate, also known as a ville integre, which was granted by the king to one of his henchment as a standard taxable unit of land paying 'gelt' to the king. Sokes seem to have originated as administrative divisions of the hundred for tax purposes.The Domesday survey indicates that they extended across parishes, but usually it only gives the owner of the soke rights for each entry without describing the extent or nature of the soke. Based on the above entries, and other evidence, it is thought that in the 11th century, Leiston, at least for tax purposes, stretched from the coast at Thorpe inland as far as Fordley and included the communities of Aldringham, Knodishall, Buxlow and Theberton. The extension of Leiston Abbey Soke into Fordley in the 13th century corresponds with Robert Malet's lands in Fordley in 1086, which were included in the Domeday valuation of Leiston. In 1399 the Abbot of Leiston was accused of claiming a soke called 'Leyston Sokene' where he had none, and of receiving complaints and delivering goods unjustly siezed within it, insisting that such pleas should be held in his court'. This was probably the pre-Conquest soke given by King William to his friend Robert Malet, which afterwards came into the possession of Runulf de Glanville who transferred it to Leiston Abbey as part of his foundation gift.
