Fortescue's most significant works were composed in Scotland and France, where the Lancastrian party had taken refuge, between 1463 and 1471. Taken together,
Opusculum de natura legis naturæ et de ejus censura in successione regnorum suprema (
A Small Work on the Nature of the Law of Nature, and on its Judgment on the Succession to Supreme Office in Kingdoms, c. 1463),
De laudibus legum Angliæ (1468–1471), and a work written in English around 1471 which was later published as
The Difference between an Absolute and Limited Monarchy (1714) His works, in particular the masterly vindication of the laws of England
De laudibus legum Angliæ, circulated in manuscript in late medieval England and were cited by the leading thinkers of the early Tudor period, among them the printer and playwright
John Rastell and the lawyer
Christopher St. Germain. based on Fortescue's c. 1471 manuscript, was published in 1714 by a descendant,
John Fortescue Aland. In the
Cotton library there is a manuscript of this work, and its title indicates that it was addressed to Henry VI. However, many passages show plainly that it was written in favour of Edward IV. A revised edition of this work, with a historical and biographical introduction, was published in 1885 by
Charles Plummer under the title
The Governance of England. Fortescue also wrote a number of mostly topical works that addressed the political conflict during the Wars of the Roses. Among the surviving works are the pamphlets
De titulo Edwardi comitis Marchiæ (
The Title of Edward, Earl of March),
Of the Title of the House of York,
Defensio juris domus Lancastriæ (
Defence of the Rights of the House of Lancaster),
Replication ageinste the Clayme, and
Title of the Duke of Yorke for the Crownes of England and France, as well as the treatise
Opusculum de natura legis naturæ et de ejus censura in successione regnorum suprema already mentioned. Two further works,
Declaration upon Certayn Wrytinges Sent oute of Scotteland and
Articles Sent to Warwick have been discussed by recent scholarship. All of Fortescue's minor writings appear in
