Answer
Adolf Hitler, the notorious German dictator, vehemently opposed Engelbert Dollfuss, the conservative Austrian Chancellor, during the 1930s. Hitler's ardent desire for territorial expansion and his strong opposition to Dollfuss's policies, which aimed to preserve Austrian independence and resist Nazi influence, fueled their intense rivalry. This ideological clash between the two leaders played a significant role in shaping the political landscape of Europe during that tumultuous era.
