text: The flag was designed by Manuel José Arce when he was named chief of the Salvadoran militia which fought against Mexico 1822, remembering the colours of the Argentinian generals San Martín and Belgrano. Arce told the idea to his wife Felipa Aranzamendi and his sister-in-law Antonia Manuela [Aranzamendi?], and they both made the Flag of El Salvador Province in white and sky blue silk.
