Asturians were involved in the development of the New World and their descendants in present-day Latin America, esp. in Argentina and Uruguay; and other countries where Asturians moved to during the rule of the Spanish Empire. The Industrial Revolution came to Asturias after 1830 with the discovery and systematic exploitation of coal and iron resources. At the same time, there was significant migration to the Americas (i.e. Mexico, Cuba and Puerto Rico); those who succeeded overseas often returned to their native land much wealthier. These entrepreneurs were known collectively as 'Indianos', for having visited and made their fortunes in the West Indies and beyond. The heritage of these wealthy families can still be seen in Asturias today: many large 'modernista' villas are dotted across the region, as well as cultural institutions such as free schools and public libraries. Asturian communities, social clubs, sporting teams, financial banks and amateur vocal groups are still found in Mexico and Argentina as well across South America.
