When Teleki committed suicide, Horthy first offered the prime ministership to Keresztes-Fischer, but when he refused it, Bárdossy was appointed. As prime minister, Bárdossy (who also retained the portfolio of foreign minister) pursued a strong pro-German foreign policy, reasoning that an alliance with the Nazis would allow Hungary to retrieve land that had been taken from it as a result of the Treaty of Trianon. On 6 April, Germany invaded Yugoslavia. Bárdossy and Horthy had agreed to allow the Germans to launch part of their invasion from Hungarian territory.
