His parliamentary activity numbered 13 years and he served as Prime Minister of the country 6 times.

[3] He was born in Tripoli, Arcadia, the son of Dimitrios Deligeorgis, a revolutionary and politician from Missolonghi who participated in the Greek War of Independence.

He was elected for the first time as an MP of Missolonghi in 1859 and openly opposed the dynasty, which resulted in his being excluded from the Parliament.

[4] He was not a proponent of the Megali Idea (Great Idea) and thought that a better solution to the Eastern Question would be to improve the condition of the Greeks living in Ottoman-controlled Macedonia, Epirus, Thrace and Asia Minor by liberalising the Ottoman Empire.

Militant demonstrations, dense columns (in journalistic publications such as "Panhellenion", "Athena", "Nea Genea"), participation in military postures, fiery speeches in parliament were some of the characteristics of this generation of politicians, who embodied the concept of the "nation in arms", i.e. the combination of nationalism and radical liberalism.
