In 1908 in Prague, in 1909 in St. Petersburg and in 1910 in Sofia, Kramář attended Pan-Slavic congresses. Along similar pan-Slavic lines, Kramář worked for a "Slavic Bloc" in the "Reichsrat" that would unite all of the parties representing the Slavic peoples into one bloc against the House of Habsburg. Kramář's pro-Russian inclinations caused much tensions with the ethnic Polish and Ukrainian politicians as both the Poles and the Ukrainians preferred to be part of the Austrian Empire rather than the Russian Empire.
