On 3/9/1843, at 1.00 am, some divisions of the army led by Colonel Kallergis, a lot of Greeks and members of the Council of State gathered at the square in front of the Palace, demonstrating in favour of the Constitution. Otto was forced to accept the convocation of a National Assembly for the composition of the first Constitution of the Greek state. The bad financial situation of the country which led it to European financial control, for which Otto was blamed, played a decisive role in the riot of 3rd September.
