Common law
The common lawso named because it was "common" to all the king's courts across Englandoriginated in the practices of the courts of the English kings in the centuries following the Norman Conquest in 1066. The British Empire spread the English legal system to its historical colonies, many of which retain the common law system today. These "common law systems" are legal systems that give great precedential weight to common law, and to the style of reasoning inherited from the English legal system.
Global commons
The term "commons" originates from the term common land in the British Isles. "Commoners rights" referred to traditional rights held by commoners, such as mowing meadows for hay or grazing livestock on common land held in the open field system of old English common law. Enclosure was the process that ended those traditional rights, converting open fields to private property. Today, many commons still exist in England, Wales, Scotland, and the United States, although their extent is much reduced from the millions of acres that existed until the 17th century. There are still over 7,000 registered commons in England alone.
