František Palacký from the Czech Republic was elected president of the All-Slavic Congress, and Stanko Vraz vice-president.
The first All-Slavic Congress began on June 2, 1848 in Prague. Delegates of all Slavic peoples except the Russians were represented at the congress, who did not send an official delegation, although some individuals came unofficially. Namely, the official policy of the Russian Empire was averse to the idea of Pan-Slavism, but later tried to use it for its own purposes.
The Croatian delegation consisted of Franjo Tkalac, Andrija Torkvat Brlić, Dragojlo Kušlan, Vatroslav Lisinski, Mato Topalović and Maksimilijan Prica. The Czechs and Slovaks were the most represented at the Congress. František Palacký, of Czech origin, was elected president of the All-Slavic Congress, and Stanko Vraz (a Slovene active in the Illyrian movement) was the vice-president.
The goals of the Pan-Slavists ranged from the creation of a homogeneous Slavic state to a loose confederation or just cultural exchange. The question of the borders of the imagined Slavic state, with or without Russia, provoked numerous heated debates. Also, numerous contradictions between the Slavic peoples (Czech-Polish, Russian-Polish, Serbian-Bulgarian, etc.) came to light, so that in the ideological sense of the unity of the Slavs it was completely missed.
The All-Slavic Congress was abruptly interrupted by the outbreak of the revolution in Prague and the approach of the Habsburg army under Field Marshal Prince Windischgrätz. Congress has just managed to issue a statement demanding the right of peoples to self-determination and condemning the oppression of Slavic peoples in Poland, Prussia, Turkey and Hungary.
