==== Clipperton Island ====
The sovereignty of [[Clipperton Island]] was settled by arbitration between [[Second French Empire|France]] and [[Mexico]]. King [[Victor Emmanuel III]] of Italy rendered a decision in 1931 that the sovereignty of Clipperton Island belongs to France from the date of November 17, 1858. The Mexican claim was rejected for lack of proof of prior Spanish discovery and, in any event, no effective occupation by Mexico before 1858, when the island was therefore ''territorium nullius'', and the French occupation then was sufficient and legally continuing.<ref name=Ireland-1941-Bdrys-Posn-Confl>{{cite book |last=Ireland |first=Gordon |year=1941 |title=Boundaries, Possessions, and Conflicts in Central and North America and the Caribbean |page=320 |publisher=Octagon Books |place=New York, NY}}</ref>
