Editing Geography of Puerto Rico (section)

===History===
The first permanent municipality of Puerto Rico, [[San Juan, Puerto Rico|San Juan]], was founded in 1521. In the 16th century two more municipalities were permanently established, [[Coamo]] (1570) and [[San Germán]] (1570). Three more municipalities were established in the 17th century. These were [[Arecibo]] (1614), [[Aguada, Puerto Rico|Aguada]] (1692) and [[Ponce, Puerto Rico|Ponce]] (1692). The 18th and 19th century saw an increase in settlement in Puerto Rico with 30 municipalities being established in the 18th century and 34 more in the 19th century. Only six municipalities were founded in the 20th century with the last, [[Florida, Puerto Rico|Florida]], being founded in 1971.<ref>[http://www.linktopr.com/fundacion.html LinktoPR.com – Fundación de los Pueblos] {{in lang|es}}. {{webarchive |url=https://web.archive.org/web/20110928214949/http://www.linktopr.com/fundacion.html |date=September 28, 2011 }}</ref>
