The 3 September 1843 Revolution (Greek: Επανάσταση της 3ης Σεπτεμβρίου 1843; N.S. 15 September), was an uprising by the Hellenic Army in Athens, supported by large sections of the people, against the autocratic rule of King Otto. The rebels, led by veterans of the Greek War of Independence, demanded the granting of a constitution and the departure of the Bavarian officials that dominated the government. The revolution succeeded, ushering the period of constitutional monarchy (under the 1844 constitution) and universal suffrage in Greece.
