The Ducoudray Holstein Expedition was an attempt by commercial interests to invade Puerto Rico and declare it the independent "Republica Boricua" in 1822. In the 1820s there was a plot to invade Puerto Rico, declare its independence from Spain, proclaim the Republica Boricua and establish its capital in Mayagüez. This invasion was different from all its precursors since none before had intended to make Puerto Rico an independent nation, and use the Taino name Boricua as the name of the republic. It was also intended more as a mercantile venture than a patriotic endeavor. It was the first time an invasion intended to make the city of Mayagüez the capital of the island.
