The sponsorship between Rastatt and the municipality of Entre Rios in southern Brazil has existed since 1988. Around 550 Danube Swabian families settled there after the Second World War. Many Danube Swabians still live in Rastatt today. In order to maintain contact between the Danube Swabians in Rastatt and the Danube Swabian ethnic group in Entre Rios, regular reciprocal visits take place.
Entre Rios is located in the highlands of the state of Paranâ in Brazil and consists of five villages. Around a third of the population living in Entre Rios is of Danube Swabian descent. The approximately 7,000 inhabitants live mainly from agriculture. Many of them work in the Agraria cooperative, which is still the economic and cultural pillar of the Danube Swabian settlement.
