After studying the historical facts, it is generally accepted that the Order of St. Jacob, known as ‘de Soevereine Orde van St. Jacob in Holland’ was founded in 1279. On the 25th of July that
year, twelve noblemen were knighted in the Ridderzaal (Knights' Hall) in The Hague. The Ridderzaal was part of the count's palace, which was situated in the Binnenhof (Inner Court).
Chivalry Orders at that time, the name of a Patron Saint was linked to the Order, and there are several theories about St. Jacob. St. Jacob was the warrior, the apostle and protector of Count Floris V. He was born on St. Jacob's day - 25th July 1254. This
might have been a deciding factor for choosing this name.
A little church was built - called St. Jacob's church - around 1270 in the ¨Buitenhof¨ (Outer Court). This church, which was
built from stone, has been renovated several times, and therefore the connection between Floris V and St. Jacob was no coincidence at that time.
