Historians have disagreed on how to characterize the political philosophies of Franz Ferdinand, some attributing generally liberal views on the empire's nationalities while others have emphasized his dynastic centralism, Catholic conservatism, and tendency to clash with other Leaders. He advocated granting greater autonomy to ethnic groups within the Empire and addressing their grievances, especially the Czechs in Bohemia and the south Slavic peoples in Croatia and Bosnia, who had been left out of the Austro-Hungarian Compromise of 1867. Yet his feelings towards the Hungarians were less generous, often described as antipathy. For Example, in 1904 he wrote that "The Hungarians are all rabble, regardless of whether they are minister or duke, cardinal or burgher, peasant, hussar, domestic servant, or revolutionary" and he regarded even István Tisza as a revolutionary and "patented traitor". He regarded Hungarian nationalism as a revolutionary threat to the Habsburg dynasty and reportedly became angry when officers of the 9th Hussars Regiment (which he commanded) spoke Hungarian in his presence — despite the fact that it was the official regimental language. He further regarded the Hungarian branch of the Dual Monarchy's army, the Honvédség, as an unreliable and potentially threatening force within the empire, complaining at the Hungarians' failure to provide funds for the joint army and opposing the formation of artillery units within the Hungarian forces.
