Konferenz von Évian
Trujillo was known for his open-door policy, accepting Jewish refugees from Europe, Japanese migration during the 1930s, and exiles from Spain following its civil war. He developed a uniquely Dominican policy of racial discrimination, Antihaitianismo ("anti-Haitianism"), targeting the mostly Black inhabitants of his neighboring country and those within the Platano Curtain, including many Afro-Dominican citizens. At the 1938 Évian Conference the Dominican Republic was the only country willing to accept many Jews and offered to accept up to 100,000 refugees on generous terms. In 1940 an agreement was signed and Trujillo donated of his properties for settlements. The first settlers arrived in May 1940; eventually, some 800 settlers came to Sosua and most moved later on to the United States.
