– experienced a decline in the use of the German language, with the exception of Brazil, where the dialect Riograndenser Hunsrückisch is being taught in schools and in some media, totaling over 200 thousand speakers spread over the Brazilian southern states. The main cause of this decrease is the integration of communities, often originally sheltered, into the dominant society, and as well as the invariable pull of societal assimilation which confronts all immigrant groups. German migration to colonial Mexico is less accounted for due to the geopolitical isolation following independence from Spain, as well as the deterrents of Mexico's ensuing civil wars. Despite these obstacles and lack of documentation however, over 200,000 Prussian/German nationals have been registered entering the country between 1860 and 1960. The first wave of Germans immigrated from northern Prussia under the reign of Princess Carlota during the 2nd French Mexican empire. Of special interest is the settlement Villa Carlota: that was the name under which two German farming settlements, in the villages of Santa Elena and Pustunich in Yucatán, were founded during the Second Mexican Empire (1864–1867). Villa Carlota attracted a total of 443 German-speaking immigrant families, most of them were farmers and artisans who emigrated with their families: the majority came from Prussia and many among them were Protestants. The second wave was during Porfirio Díaz's open settlement policy in the Yucatán Peninsula that favored and attracted many Europeans. Most German-speaking or self identifying German-Mexicans today are descended from these two events as well as around 20,000 ethnic Germans from Russia and around 100,000 Mennonites from Canada. Specific reasons for language change from German to the national language usually derive from the desire of many Germans to belong to their new communities after the end of World War II. This is a common feature among the German minorities in Latin America and those in Central and Eastern Europe: the majority of countries where German minorities lived had fought against the Germans during the war. With this change in situation, the members of the German minorities, previously communities of status and prestige, were turned into undesirable minorities (though there were widespread elements of sympathy for Germany in many South American countries as well). For many German minorities, World War II thus represented the breaking point in the development of their language. In some South American countries the war period and immediately afterwards was a time of
