King should hold a parliament at least once a year for the next three years so, "that his subjects are served by the law". In 1318, a parliament at Scone enacted a code of law that drew upon older practices, but it was also dominated by current events and focused on military matters and the conduct of the war. Nevertheless, the Act also codified procedures for criminal trials and protections for vassals from ejection from the land. Scotland's three oldest universities, the University of St Andrews, the University of Glasgow and the University of Aberdeen were also founded following the wars and the Education Act 1496 was passed requiring those who administered justice in Scotland to learn Latin and study law for at least 3 years at school. From the 14th century we have surviving examples of early Scottish legal literature, such as the Regiam Majestatem (on procedure at the royal courts) and the Quoniam Attachiamenta (on procedure at the baron courts). Both of these important texts, as they were copied, had provisions from Roman law and the ius commune inserted or developed, demonstrating the influence which both these sources had on Scots law. Stewart Dynasty The Stewart dynasty, founded by King Robert II in 1371, was defined by the growing authority and power of the Scottish Kings and development of existing legal institutions. In 1469, the Parliament of Scotland affirmed the ultimate authority of King James III and rejected the authority of imperial notaries in Scottish civil matters. The recognition of the sovereign authority of the Scottish Kings was connected to the influence of the ius commune in Scots law. For example, the Pragmatic Sanction of Bourges of 1438 was an attempt to limit papal authority in France and recognise the sovereign authority of King Charles VII of France. Various customary laws, such as the Law of Clan MacDuff, came under attack from the Stewart Dynasty which consequently extended the reach of Scots common law. From the reign of King James I to King James V the beginnings of a legal profession began to develop and the administration of criminal and civil justice was centralised. The Parliament of Scotland was normally called on an annual basis during this period, with the notable exception of King James IV, and its membership was further defined. The number of burghs also continued to expand, including the introduction of burghs of barony, and
