France's National Constituent Assembly is dissolved, to be replaced the next day by the National Legislative Assembly.
On September 30, 1791, France's National Constituent Assembly was officially dissolved, paving the way for the National Legislative Assembly to assume power the following day.
The French Revolution saw sweeping changes in governance as the National Constituent Assembly, which had crafted the 1791 Constitution, concluded its work on 30 September 1791. The dissolution was part of a structured transition designed by revolutionaries to usher in a new legislative body under the constitutional monarchy. On 1 October 1791, deputies would reconvene as the National Legislative Assembly, charged with enacting laws and supervising the king. This transition reflected growing political divisions between moderates and radicals within revolutionary France. The new assembly faced immediate challenges, including economic turmoil, royal dissent, and foreign hostility. Its formation underscored the Revolution's commitment to orderly progression of representative government despite widespread upheaval. The Legislative Assembly would later confront the crisis that led to the monarchy's fall and the rise of the Republic.

Britain, France, Germany and Italy sign the Munich Agreement, whereby Germany annexes the Sudetenland region of Czechoslovakia.
France, Britain, Germany and Italy sign the Munich Agreement, conceding the Sudetenland to Nazi Germany and attempting to avert war.
In an attempt to avoid a major European war, British Prime Minister Neville Chamberlain and French leaders agreed to Adolf Hitler’s demands that the Sudetenland region of Czechoslovakia be annexed to Germany. The treaty, negotiated in Munich on September 30, 1938, excluded Czechoslovak representatives from the talks. It was hailed at the time as securing “peace for our time,” but in reality it emboldened Hitler’s expansionist ambitions. The agreement is widely regarded as the pinnacle of appeasement policy. Within months, Germany invaded the rest of Czechoslovakia, and World War II erupted in 1939. Historians view the Munich Agreement as a failed diplomatic effort that delayed but did not prevent the coming global conflict.
