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.
Thomas Reade Rootes Cobb
Cobb was also one of the founders of the University of Georgia School of Law, and served on the first Georgia code commission of 1858 and drafted what became the private and penal law portions of the Georgia Code of 1861, which was the first successfully enacted attempt at a comprehensive codification of the common law anywhere in the United States. It is the ancestor of today's Official Code of Georgia Annotated. Simultaneously, the Northern law reformer David Dudley Field II was independently working in the same ambitious direction of trying to codify "all" of the common law into a coherent civil code, but Field's proposed civil code was not actually enacted until 1866 in Dakota Territory, was belatedly enacted in 1872 in California, and was repeatedly rejected several times by his home state of New York and never enacted in that state. Unlike Field's largely race-neutral code, the original Georgia Code was strongly biased in favor of slavery and white supremacy, and even contained a presumption that blacks were "prima facie" slaves until proven otherwise. Georgia ultimately kept the Code after the Civil War but revised it in 1867 and many more times since, to purge the racism and pro-slavery bias inherent in the original text.
