City of London Corporation

The City of London Corporation, officially and legally the Mayor and Commonalty and Citizens of the City of London, is the local authority of the City of London, the historic centre of London and the location of much of the United Kingdom's financial sector.

In 2006, the name was changed from Corporation of London to distinguish the body governing the City of London from the Greater London Authority, the regional government of the larger Greater London administrative area. It is a corporation in the sense of being a municipal corporation rather than a company; it is deemed to be the citizens and other eligible parties acting as one corporate body to manage the City's affairs. The corporation is based at the Guildhall.

Both businesses and residents of the City, or "Square Mile", are entitled to vote in corporation elections. In addition to its functions as the local authority (analogous to those undertaken by the 32 boroughs that administer the rest of Greater London) the City of London Corporation takes responsibility for supporting the financial services industry and representing its interests. The corporation's structure includes the Lord Mayor, the Court of Aldermen, the Court of Common Council, and the Freemen and Livery of the City. The "Liberties and Customs" of the City of London are guaranteed in Magna Carta's clause IX, which remains in statute.

In the Anglo-Saxon period, consultation between London's rulers and its citizens took place at the Folkmoot. Administration and judicial processes were conducted at the Court of Husting and the administrative part of the court's work evolved into the Court of Aldermen.

There is no surviving record of a charter first establishing the corporation as a legal body, but the City is regarded as incorporated by prescription, meaning that the law presumes it to have been incorporated because it has for so long been regarded as such (e.g. Magna Carta states that "the City of London shall have/enjoy its ancient liberties"). The City of London Corporation has been granted various special privileges since the Norman Conquest, and the Corporation's first recorded royal charter dates from around 1067, when William the Conqueror granted the citizens of London a charter confirming the rights and privileges that they had enjoyed since the time of Edward the Confessor. Numerous subsequent royal charters over the centuries confirmed and extended the citizens' rights.

Around 1189, the City gained the right to have its own mayor, later being advanced to the degree and style of Lord Mayor of London. Over time, the Court of Aldermen sought increasing help from the City's commoners and this was eventually recognised with commoners being represented by the Court of Common Council, known by that name since at least as far back as 1376. The earliest records of the business habits of the City's chamberlains and common clerks, and the proceedings of the courts of Common Council and Aldermen, begin in 1275, and are recorded in fifty volumes known as the Letter-Books of the City of London.

The City of London Corporation had its privileges stripped by a writ quo warranto under Charles II in 1683, but they were later restored and confirmed by Act of Parliament under William III and Mary II in 1690, after the Glorious Revolution.

With growing demands on the Corporation and a corresponding need to raise local taxes from the commoners, the Common Council grew in importance and has been the principal governing body of the City of London since the 18th century.
