Not later than in the 16th century, the Slovaks regarded the double cross also as a symbol of their nation. This fact manifested itself during the Revolution of 1848/1849, Slovaks were fighting along with the Austrians against the Hungarians (though many Slovaks chose to defend the Hungarian case). A "Slovak National Council" was established for this purpose in August 1848 in Vienna. The present-day coat of arms was used on the seal of this Slovak National Council for the first time officially as the national symbol of the Slovaks (instead of being the official symbol of Upper Hungary only). From that time onwards, the symbol has been used very frequently.
