The article is devoted to the work of Northumberland and Cumberland local government in 1528-1536. The period 1528-1536 was one of the richest of events in the history of the royal policy towards anglo-scottish borderlands. It included the restoration of aristocratic families of Percy and Dacre power, war with Scotland, removing of William, Lord Dacre from the post of Warden of the West Marches. These events must have had an influence on work of commission of peace, the backbone of Tudor local government. The subject of this article is to study changes in personnel and scope of commission of peace of Northumberland and Cumberland. As the analyses show, the number of justices of peace rose to 36-39 in Northumberland and 25-31 in Cumberland. There were some groups in peace commission: the officers of central and border administration, justices of assizes and local nobility and gentry. The members of Duke of Richmond’s Council comprised a significant part of justices of peace. The personnel of peace commission demonstrate the strong positions of Henry Percy, the 6th Earl of Northumberland and his entourage not only in Northumberland, but also in Cumberland. William, Lord Dacre, didn’t acquire the same degree of authority and influence as his father, Thomas, Lord Dacre of Gillsland. The predominance of strangers in the peace commissions of border shires lead to the scarcity of justices who could attend sessions and dealt with local problems regularly. So, as show this research the changes in royal policy towards methods of government of borderlands didn’t modify the ultimate characteristics of local peace commissions: irregularity of renewal, scarcity of aborigine personnel of justices of peace, a lot of justices, derived from another shires and central administration.
