In 1707, the year of the unification of the Kingdoms of Scotland and England into the Kingdom of Great Britain, Queen Anne established the Chair of Public Law and the Law of Nature and Nations in the University of Edinburgh, to which Charles Erskine (or Areskine) was appointed; this was the formal start of the Faculty of Law. By 1722 the University had four Professors of Law, and classes—in Civil Law, Scots Law and History—were usually given in their respective homes or offices. Numbers grew with the expansion of the legal profession in the 19th century, and by 1830 there were over 200 students attending the Scots Law class alone. Scholarship amongst the academics at Edinburgh continued to grow in reputation, with the work of Muirhead, Lorimer and Rankine achieving international renown.
