Constitutional Convention of Puerto Rico

On June 8, 1950, the United States government approved Public Law 600, authorizing Puerto Rico to draft its own constitution in 1951. The Constitutional Assembly met for a period of several months between 1951 and 1952 in which the document was written. The framers had to follow only two basic requirements established under Public Law 600. The first was the document must establish a republican form of government for the island. The second was the inclusion of a Bill of Rights.

The Constitution of Puerto Rico renamed the body politic until then known as "People of Puerto Rico", and henceforth known as the "Commonwealth of Puerto Rico" (Estado Libre Asociado).
