When Charles III became King of Spain, he observed that most of the countries in Europe used flags which were predominantly white and, since they were frequently at war with each other, lamentable confusions occurred at sea, it being difficult to determine if a sighted ship were enemy until practically the last moment. For this reason, he ordered to his Minister of the Navy to present several models of flags to him, having to be visible from great distances. The Minister selected twelve sketches which were shown to the king. The flag that was chosen as war ensign is the direct ancestor of the current flag. It was a triband red-yellow-red, of which the yellow band was twice the width of the red bands, a unique feature that distinguished the Spanish tribanded flag from other tribanded European flags. The flag chosen as civil ensign or for Merchant Marine use, meanwhile, consisted of five stripes of yellow-red-yellow-red-yellow, in proportions 1:1:2:1:1.
