Petrakis and had Makriyannis placed under house arrest. Sometime during this period, Makriyannis commissioned 25 engravings from the painter and veteran of the War of Independence, Panaghiotis Zographos. The profits from the sales were used to the benefit of veterans of the war. Meanwhile, the demand for constitutional liberties was becoming widespread, as was discontent with King Otto's Bavarian administration. The situation escalated in the 3 September 1843 Revolution that led to the granting of the first Constitution. Makriyannis was one of the three leaders of the movement. He played a crucial part in paving the way for this, having started as early as 1840. After its granting, he also played an important part in the forming of the new cabinet. He was elected as a representative of Athens to the National (Constitutional) Assembly, and headed an informal group of 63 representatives loyal to him.

He was always outspoken about his views, and as a result he stirred negative reactions among his opponents. He opposed what he perceived as a continued degradation of the veterans of the War of Independence, and had repeatedly been considered suspect of plotting against King Otho. Furthermore, the King never quite forgave him for his part in the 3 September movement. When summoned to the palace and asked to denounce all the conspirators of 1843, Makriyannis refused, saying "I am not a slave". Eventually, in 1852, he was accused of planning to "overthrow the establishments and assassinate the King". On 13 April 1852 he was placed under house arrest, heavily guarded and with an officer posted in the room next to his own. On 16 March 1853 he was sentenced to death, in what has been called
