Vienna was wracked by the revolutions of 1848 in the Austrian Empire and the intense rivalry between father and son became much more apparent. Johann Jr. decided to side with the revolutionaries. It was a decision that was professionally disadvantageous, as the Austrian royalty twice denied him the much coveted 'KK Hofballmusikdirektor' position, which was first designated especially for Johann I in recognition of his musical contributions. Further, the younger Strauss was also arrested by the Viennese authorities for publicly playing "La Marseillaise", but was later acquitted. The elder Strauss remained loyal to the monarchy and composed his "Radetzky March", Op. 228 (dedicated to the Habsburg field marshal Joseph Radetzky von Radetz), which would become one of his best-known compositions.
