autonomy. This was never completely implemented due to Hungarian resistance, demanding the full autonomy lost in 1849. Consequently, the October Diploma (Oktoberdiplom) was replaced by the February Patent (Februarpatent), in 1861 establishing a bicameral legislative body, the Reichsrat. The upper house (Herrenhaus) consisted of appointed and hereditary positions, while the lower house, the House of Deputies (Abgeordnetenhaus) was appointed by the provincial diets. The Reichsrat would meet with or without the Hungarians, depending on the issues being considered. This was a first step towards the establishment of a separate Cisleithanian legislature, on the other hand the more limited role of the diets in the February Patent, compared to the October Diploma, angered the champions of regionalism. The Reichsrat was dominated by liberals, who were to be the dominant political force for the next two decades. The Danish question (1864–66) Prussia and Denmark had already fought one war in 1848–51 over the territories that lined their common border, Schleswig-Holstein which resulted in Denmark retaining them. By 1864 Austria was at war again, this time allying itself with Prussia against Denmark in the Second Schleswig War, which although successful this time, turned out to be Austria's last military victory. The war concluded with the Treaty of Vienna by which Denmark ceded the territories. The following year the Gastein Convention resolved the control of the new territories, Holstein being allocated to Austria, after initial conflicts between the allies. However this did little to ease the Austria–Prussia rivalry over the German question. The ongoing efforts by Otto von Bismarck, the Prussian Minister President, to revoke the agreement and wrest control of the territories would soon lead to all out conflict between the two powers and achieve the desired weakening of Austria's position in central Europe.

Hungary had little support in the court at Vienna which was strongly Bohemian and considered the Hungarians as revolutionaries. From the loss of the Italian territories in 1859, the Hungarian question became more prominent. Hungary was negotiating with foreign powers to support it, and most significantly with Prussia. Therefore, Hungary represented a threat to Austria in any opposition to Prussia within the German Confederation over the German Question. Therefore,
