The origins of the 4th of June date back to the late part of the 18th Century to celebrate the birthday of George III, one of the School’s greatest patrons.
The first water pageants were very informal indeed, run entirely by the boys, who would amuse themselves by rowing up and down the river in fancy dress, with flags and bunting adorning the boats, all of which was done without the Headmaster’s permission.
The first procession took place in 1793 on the King’s birthday and continued in a relaxed manner for a number of years until matters came to a rather embarrasing head, when King William IV asked if he may watch the procession which, the Headmaster Dr. Keate had to decline on the grounds that he:
“Did not know there was such a thing”.
Rowing was not formally accepted by the School until 1840 and only actively encouraged after 1860.
The actual procession is lead by the Monarch, a unique boat with ten oarsmen including; the Captain of the Boats (Capt. of the VIII), the Ninth Man in the Monarch (organiser policing and matters to do with the river), the Captain of the School (Colleger), the Captain of the Oppidans and for a time, the Captain of the XI amongst others, down to the most junior VIII, Defiance.
