During the Hook and Cod wars in 1402, Haarlem formed a hand bow schutterij under the patronage of St. George of 120 citizen volunteers to support the local court of Justice. The guild-like group had its own altar in the St. Bavochurch and they even had processions through town on the name day of their saint. The town suffered from uprisings in 1417 and 1422. After another uprising in 1425, a "New" schutterij was formed to educate young men in the use of the crossbow and they defended the city in 1426 against Jacoba of Beieren. The "New" crossbow schutterij had a new meeting hall built for them near the Spaarne river, and in 1468 a separate schutterij was formed under the patronage of St. Sebastian for hand bowmen. Around 1500 Haarlem had three schutterij groups, two (old and new) under the patronage of St. George (St. Joris), and one under the patronage of St. Sebastian, all with their own altars in church.
