After many years, a Diet was convened in Bratislava in 1825. The reason why it was convened is that there were some international problems in 1820. The king, Francis I promised to return to the feudal constitution, but in exchange the nobility had to increase the tax and rookie headcount. This diet weren’t a Reform Diet, but this was the first one in which some progress were made: they had to convene the parliament/diet every 3 years and István Széchenyi offered his annual income to establish a Hungarian Academy of Sciences.
