From March 11, 1848 (Assembly in Svatováclavské lázně) there was a political unrest in
Prague, by which Prague joined the
wider revolutionary current in the whole of Europe. At that time, Czech politics had already split into a
liberal current (
František Palacký,
Karel Havlíček Borovský) and a
radically democratic one (
Karel Sabina,
Josef Václav Frič,
Vincenc Vávra Haštalský,
Vilém Gauč,
Emanuel Arnold). In the first phase, the moderate liberals prevailed. They preferred constructive and cautious steps, such as the establishment of the
St. Wenceslas Committee on March 12. On 19 and 31 March, the Committee prepared two petitions to the Emperor, which mainly included the requirements of linguistic equality, the establishment of the
National Newspaper (April 5), the transformation of the St. Wenceslas Committee into the National Committee (April 10), Palacký's Writing in Frankfurt (April 11), founding of the
Lípa slovanská association (April 30), organization of the
Slavic Congress (June 2-12). Meanwhile, the radical wing also strengthened. On June 1, its press body, the
Prague Evening Paper, began publishing. It was then supported by the arrival of some delegates to the Slavic Congress (especially
Mikhail Bakunin). At the beginning of June, the commanding general in
Bohemia,
Alfred Windischgrätz, decided that the growing tensions would be dampened by military demonstrations of force - military patrols were constantly passing through the city, artillery batteries were deployed on
Petrin and
Vysehrad, a massive military parade was held on June 7, with military reinforcements from
Kutná Hora and
Hradec Králové. This then increased tensions in the city. On June 11, Prague students met in
Karolinum and sent a deputation to Windischgrätz, demanding that the army ease the situation. They were rejected, after which the students issued them as a leaflet and hung them around Prague (the so-called
Red Poster). On the evening of June 11, an assembly met at the in to discuss the situation. It decided to hold a mass demonstration (so-called "fraternal mass") on the second day at the Horse Market (today's
Wenceslas Square). ==Uprising==
