The flag of the Commonwealth of Puerto Rico which was adopted by the legislative assembly in 1952 is based on a flag designed by a group of patriots in the year 1895, and has its roots in the flag of the Cuban Republic.

 

The white star represents the Commonwealth and the blue triangle whereupon it rests represents the republican form of government of the island with its three independent branches: the Executive, the Legislative and the Judicial. The three red stripes signifies the blood that feeds the three brnches of government and the two white stripes signify the freedom of man and the rights of the individual that keep the three branches of government in check.

The seal of the Commonwealth of Puerto Rico has several figures that also are present in the seal that the Spanish Crown gave to Puerto Rico in the early part of the XVI century.

In the green center the lamb represents peace and confraternity. Above the lamb the rack of arrows represents the creative force. The two letters F and I stand for the Spanish names of the Spanish kings, Fernando and Isabel, at the time of the discovery of the island. The sentence below in Latin translates into Juan is its name, since Puerto Rico was first known as San Juan, which today is the name of its capital city. Around the green circle you have the towers of Castile, the lions of Leon, the crosses of Jerusalem, and Spanish flags that signify Puerto Rico's hispanic heritage..
