It was most influential among Czech liberals around the middle of the 19th century. First proposed by Karel Havlíček Borovský in 1846, as an opposition to the concept of pan-Slavism, it was further developed into a complete political program by Czech politician František Palacký. Austroslavism also found some support in other Slavic nations in the Austrian Empire, especially the Slovenes and Croats.
Austroslavism envisioned peaceful cooperation of the smaller Slavic nations of Central Europe within the Habsburg Monarchy not dominated by German-speaking elites. Palacký proposed a federation of 8 national regions, with significant self-governance. After the suppression of the Czech revolution in Prague in June 1848, the program became irrelevant. Austrian Empire transformed to Austria-Hungary (1867), honouring Hungarian, but not Slavic demands as part of the Ausgleich. This further weakened the position of Austroslavism.
As a political concept, Austroslavism persisted until the fall of the Austrian-Hungarian Empire in 1918. It was exhibited in several uninfluential proposals to federalise Austria-Hungary, e.g. that of Aurel Popovici (see United States of Greater Austria).
