Whilst Henry II's own primary concern was the maintenance of peace and the punishment of crime, new procedures concerning land cases also featured prominently in the Angevin reforms. These developments had an impact not just upon the conduct of cases in court but also the enabling and preventative functions of law, and upon the substantive matters of security of tenure, heritability, and alienability. However, it is vital to remember that the changes in land law in the Angevin period were caused not solely by the reforms. Some influences, such as the learned law notions of possessio and proprietas, worked both through and independently of the reforms. Moreover, the various longer-term causes that had been securing the position of the tenant and his heirs by 1135 continued throughout our period. 1
