Spain

The Spanish flag, known as "la Rojigualda," has a rich history dating back to 1785 when King Charles III chose it as the naval ensign. The current design was officially adopted on December 19, 1981, after Spain's transition to democracy. The flag's distinctive red and yellow horizontal stripes can trace their roots to the medieval Crown of Aragon's colors. The center emblem, featuring the royal coat of arms, represents Spain's constitutional monarchy.
