Who came first the Cuban flag or the Puerto Rican flag?

The Cuban flag was adopted first, officially becoming the national flag of Cuba on May 20, 1902. The Puerto Rican flag was created later, with its current design being adopted in 1952. However, a version of the Puerto Rican flag resembling the current one was first used in 1895, during the Cuban War of Independence. Thus, while the Cuban flag was officially adopted earlier, both flags share historical ties and influences.
