Jus exclusivae: Jus exclusivæ (Latin for "right of exclusion"; sometimes called the papal veto) was the right claimed by several Catholic monarchs of Europe to veto a candidate for the papacy.  The French monarch, the Spanish monarch, the Holy Roman Emperor, and the Emperor of Austria claimed this right at various times, making known to a papal conclave, through a crown-cardinal, that the monarch deemed a particular candidate for the papacy objectionable.

List of the last monarchs in the Americas: The Native American hereditary leaders during this time are not included.  Those that are listed as former monarchs of what is now the continental United States were heads of European seated monarchies (or Mexican monarchs, such as Agustín I of Mexico and Maximilian I of Mexico) and themselves never set foot on American soil.  Others were indigenous monarchs, such as Malietoa Tanumafili I, Tuʻi Manuʻa Elisala and Liliuokalani of Hawaii; The last monarch of each state and territory may not be the last colonial ruler (i.e. Louis XV of France is the last French monarch of Louisiana, but Napoleon Bonaparte, prior to becoming Emperor, was the last ruler of Louisiana).  Also their end of reign may not be how the US acquired these states.  One state can have more than one last monarch, since each state may have been the product of many different acquisitions by the United States.  Different claims of a foreign country are taken into account.

Philip was given the nickname "Augustus" by the chronicler Rigord for having extended the Crown lands of France so remarkably.
