After the St. Lucia's flood in 1287 the part of Frisia west of the later Zuiderzee, West Friesland, was conquered. As a result, most provincial institutions, including the States of Holland and West Frisia, would for more than five centuries refer to "Holland and West Frisia" as a unit. The Hook and Cod wars started around this time and ended when the countess of Holland, Jacoba or Jacqueline was forced to cede Holland to the Burgundian Philip III, known as Philip the Good, in 1432.
