The Estrelada (Valencian pronunciation: [estɾeˈlaða]) or Valencian nationalist senyera is a flag of Valencia that evolved from the flag of Valencia city. The white star version is used by Valencian nationalist groups since the early 20th century. Some of these groups may even be of blaver ideology, especially those with more pro-sovereign positions. The oldest conserved document with a reference, with a red star, is a war poster of Valencian Left.
