Otto came of age in 1835 and assumed the reins of government, but Bavarians remained as heads of the government until 1837. Otto thereafter appointed Greek ministers, although Bavarian officials still ran much of the army. At this time, Greece still had no legislature and no constitution. Discontent at the continued "Bavarocracy" grew until the 3 September 1843 Revolution broke out in Athens. Otto agreed to grant a constitution and convened a National Assembly that met in November of the same year. The Greek Constitution of 1844 then created a bicameral parliament consisting of an Assembly ("Vouli") and a Senate ("Gerousia"). Power then passed into the hands of a group of Greek politicians, most of whom who had been commanders in the War of Independence against the Ottomans.
