The document summarizes the history of the Spanish flag from 1492 to present day. It describes how the first flag was a banner for the Catholic Monarchs in 1492-1505. The flag then became a white flag with the cross of Burgundy under Juana I and Felipe of Habsburg. Several changes were made over time for visibility at sea, including removing the crown during the First Spanish Republic and restoring it in 1784 with the monarchy. The current flag design was established in 1981.
