Cultural citizenship—or what Renato Rosaldo has called, "the right to be different and to belong, in a democratic, participatory sense" (1996:243)—is not yet very well developed in Peru. This is perhaps no more apparent than in the country's Amazonian regions where indigenous societies continue to struggle against state-sponsored economic abuses, cultural discrimination, and pervasive violence.

The largest immigration wave occurred as a result of the Salvadoran Civil War in the 1980s, in which 20–30% of El Salvador's population emigrated.

Document 11: 51st state: Due to geographical proximity of the Central American countries to the U.S. which has powerful military, economic, and political influences, there were several movements and proposals by the United States during the 19th and 20th centuries to annex some or all of the Central American republics (Costa Rica, El Salvador, Guatemala, Honduras with the formerly British-ruled Bay Islands, Nicaragua, Panama which had the U.S.-ruled Canal Zone territory from 1903 to 1979, and formerly British Honduras or Belize since 1981). However, the U.S. never acted on these proposals from some U.S. politicians; some of which were never delivered or considered seriously. In 2001, El Salvador adopted the U.S. dollar as its currency, while Panama has used it for decades due to its ties to the Canal Zone.

The Spanish, U.S. silver dollars, and later, Mexican silver pesos circulated side by side in the United States, and the Spanish dollar and Mexican peso remained legal tender until the Coinage Act of 1857. The coinage of various English colonies also circulated. The lion dollar was popular in the Dutch New Netherland Colony (New York), but the lion dollar also circulated throughout the English colonies during the 17th century and early 18th century. Examples circulating in the colonies were usually worn so that the design was not fully distinguishable, thus they were sometimes referred to as "dog dollars".
