The Dutch nation fought for independence during the Eighty Years' War, and Hals was a member of the local schutterij, a military guild. He included a self-portrait in his 1639 painting of the St Joris company, according to its 19th-century painting frame. (It has not been possible to confirm this.) It was not common for ordinary members to be painted, as that privilege was reserved for the officers. Hals painted the company three times. He was also a member of a local chamber of rhetoric, and in 1644 he became chairman of the Guild of St Luke.
