Prior to the Kingdoms of Scotland and England &amp; Wales unification as the Kingdom of Great Britain, Scots Property law was largely governed by Acts of the Parliament of Scotland and common law decisions by the Scottish judiciary. Its roots predominantly lay in Roman law and the "ius commune", however feudalism was also introduced into Scots property law as a result of the Davidian Revolution in the 12th century so the legal system developed a distinct property law. In the 17th and 18th century, a group of academics, now called the institutional writers, wrote authoritative texts on large areas of Scots law, including property law, which came to be regarded as a formal source of law from the 19th century onwards.
