German Chileans (; ) are Chileans descended from German immigrants, about 30,000 of whom arrived in Chile between 1846 and 1914. Most of these were from Bavaria, Baden and the Rhineland, and also from Bohemia in present-day Czech Republic, which were traditionally Catholic. A smaller number of Lutherans immigrated to Chile following the failed revolutions of 1848. From the middle of the 19th century to the present, they have played a significant role in the economic, political and cultural development of the Chilean nation. The 19th-century immigrants settled chiefly in Chile's Araucanía, Los Ríos and Los Lagos regions in the so-called Zona Sur of Chile, including the Chilean lake district. History Germans in the Spanish colony The first German to feature in the history of what is now Chile is Bartolomé Blumenthal (Spanish alias Bartolomé Flores) during the 16th century who accompanied Pedro de Valdivia. The latter conquistador ousted the indigenous population and founded the city of Santiago. Valdivia also arrested and took hostage the Cacique (tribal leaders and chiefs) to weaken the society of the local Mapuche people. Blumenthal took part in the defence of the Spanish settlement of Santiago when the Mapuche launched a counter-offensive on 11 September 1541 in attempt to free their caciques held hostage by the conquistadores. Later Blumenthal took part in the consolidation of the Spanish settlement that would become the Talagante Province; he was the first engineer in the remote colony. Blumenthal's son-in-law, Pedro de Lisperguer (born Peter Lisperger in Worms, Germany), was appointed as mayor of Santiago in 1572. Johann von Bohon (known in Spanish as Juan Bohón) was also part of Valdivia's expedition and was ordered to establish the city of La Serena in 1544. 19th century Hamburg and Valparaíso In 1818 Chile became independent from Spain and began to engage in trading with more nations. The port city of Valparaíso became a major center for trade with Hamburg, with commercial travellers and merchants from Germany staying for lengthy periods of time to work in Valparaíso. Some settled there permanently. On 9 May 1838 Club Alemán de Valparaíso, the first German cultural organization was established in the city. German residents and visitors held cultural functions here. The club began to organize literary, musical and theatre productions, contributing to the cultural life of the city. Aquinas Ried, a physician, became widely known in the city for composing operas, and for writing poetry
