The
Regiam Majestatem was written perhaps as early as the time of
Robert the Bruce (reigned 1306 – 1329), and certainly later than 1318, as a statute from that date was included in it. The details of how this was accomplished are unknown, as is the identity of the author.
Background In the events leading up to his invasion of Scotland,
Edward I of England (reigned 1272–1307) forced himself upon Scotland in the role of
feudal overlord, far beyond the guiding and consultative role that the Scots had asked him to play. During this time he signed a
writ in 1291 that required the collection of all documents that might concern his own claims of superiority over Scotland, or the claims of others. The writ was executed, and between that and the depredations during Edward's invasion of Scotland in 1296, virtually every important Scottish legal document was lost forever. The Scots successfully maintained their freedom in the
First War of Scottish Independence, which ended
de facto with the
Battle of Bannockburn in 1314, ending
de jure in 1328 with the
Treaty of Edinburgh–Northampton. Effective government required a legal basis and its documentation, and the Scots were forced to rebuild their legal provenance quickly.
Origin The origin of the contents of the
Regiam Majestatem is largely from Glanvill's
Tractatus. About two-thirds of the work was adopted without change from it, parts of the remainder are similar to it, and the rest is unrelated to it. This last category includes most of the fourth book, which covers the treatment of crimes. Of the portions which do not originate with the
Tractatus, their origins can be found in
canon law, in the
Summa in Titulos Decretalium of
Goffredus of Trano, in the
Laws of the Brets and Scots, and in earlier Scottish statutes. The
Tractatus was a work of originality intended to facilitate the implementation an effective judicial system in England, and it had proven to be a great success. The Scots were certainly aware of this, and it was likely chosen over other
codifications because it best suited Scottish interests by providing a framework that had already proved itself to be successful, and one that addressed issues particular to Scottish law, but issues that mostly were common to both Scottish and English law. Where it was close to Scottish interests but not close enough, that is the likely origin of those portions of the
Regiam Majestatem that appear only similar to the
Tractatus. Nevertheless, the fit was not perfect, and there are artefacts from English law that do not fit well with Scottish customs.
Ancestral ancestry • Glanvill's
Tractatus – it is the
book of authority on English
common law, and has been studied and analysed in detail. There is consensus that the English law ultimately does not rely on earlier codifications.
Scrutton noted the lack of a heritage owed to Roman law (i.e., the
Corpus Juris Civilis) in the
Tractatus, stating that some terminology was borrowed solely to be fitted into the book discussing Contracts (
Tractatus, Book X), but that the terms were applied to English concepts.
Pollock and
Maitland, in their
History of English Law Before the Time of Edward I, describe Glanvill's contracts as "purely Germanic", and state that the "law of earnest is not from Roman influence". • Canon law • Geoffrey's
Decretal • Laws of the Brets and Scots – Book IV of the
Regiam Majestatem, covering crimes, incorporates chapters from this document, preserving the
Celtic names for descriptions of people, kinship groups, and fines. Terms used include the , , (''), and . Fines are structured according to the class of the victim, the fines might be paid to the king or to the victim's kindred depending on the circumstances, and payments to be made are given in cattle or
orae. • earlier Scottish statutes • Roman law == The document ==
