István Bethlen's speech in Debrecen in March 1928 was an important event in the Hungarian revision policy between the two world wars. Among the foreign policy conditions that became more favourable at the end of the decade, the humble tone of the Prime Minister changed. In this speech, he formulated a demand for a more proactive revision policy by the Hungarian government. In the study, I covered the antecedents of the speech, and examined its content and most important ideas. My article focuses primarily on the statements in the speech that marked a shift from the cautious revision policy of the period 1920–1927, setting the tone for the foreign policy events of the 1930s.
