Standard Portuguese (português padrão) is traditionally based on the Estremenho dialect of Coimbra, where the oldest university of the country existed for centuries, and, currently, also Lisbon, despite the pronunciation of Lisbon is still perceived by many as a dialect. Being the standard form and because most African and some Asian politicians studied in Portugal, it is also the standard form of the spoken and written language in the former Portuguese colonies in Africa and Asia (Angola, Mozambique, Guinea-Bissau, Cape Verde, São Tomé and Príncipe, East Timor, Macau, Daman, Diu and Goa) and also in Venezuela, Namibia, South Africa, France, Germany, Canada, United States and Luxembourg (where Portuguese emigrants are most numerous), although there is a very wide variety of regional dialects.
