Caribbean Similarities: Cuba and Puerto Rico

I've always wondered if the one of the flags of either Cuba or Puerto Rico inspired the other, considering the similarities.

It turns out that's correct. Cuba had their flag designed during their fight for independence against the Spanish, as they were one of the last nations to gain their independence from Spain. It had been floating around the island since 1849, and was adopted in 1902.

Here it is:

Puerto Rico had a different flag they associated with themselves, even though they've never really gained any significant independence. It resembled today's Dominican Republic flag. In 1892, they designed one that was based on Cuba's, but with the colors switched. It was adopted and made their official flag of their Commonwealth in 1952.

The quickest way to tell the difference: Puerto Rico, still a territory of the US, has, like the US red and white stripes with the blue hoist triangle, and Cuba's the opposite.
