The National Gathering of Hungarian Noblemen was tantamount to the modern Hungarian parliament.
In 1790 a man named Péter Bárány petitioned the National Gathering of Hungarian Noblemen in the name of Hungarian mothers to grant female nobles the right to observe the Gathering's proceedings. He argued that these women would be better prepared to raise politically active, patriotic sons, but the assembly did not accept his petition.
