Today, Michaelmas Day, is the day of the election of the new Lord Mayor of the City of London, the leader of the City of London Corporation, in the so-called “Common Hall” in the Guildhall (*). According to equally long-standing tradition, the new Lord Mayor will formally assume office, in the so-called “Silent Ceremony”, on the Friday before the second Saturday in November; and the Lord Mayor’s show will take place on the following day.
(*) The first (Lord) Mayor to be appointed, by King Richard I, was Henry Fitz-Ailwyn de Londonestone, in 1189. The first to be elected by peers, under the “Mayoral Charter” of King John, was Serlo de Mercer, in 1215. Such was the prestige of the position that the by-then Lord Mayor, William Hardel(l), was invited by King John to be a witness to the sealing of, and an Enforcer or Surety of, the Magna Carta, later in 1215.
