Reign of King Otto, 1843–1862

When King Otto arrived in Greece, he was still a minor, and until 1835 the country was governed by a regency council. The regents ignored the so-called "Hegemonic Constitution [fr]" voted by the Fifth National Assembly, and when Otto assumed full powers, he ruled as an absolute monarch. The only "parliamentary" body was the 20-member Council of State (Συμβούλιο της Επικρατείας), but its role was purely consultative and it was strictly controlled by the King.

The 3 September 1843 Revolution forced Otto to grant a constitution, which was promulgated by the "3rd of September" National Assembly [el]. The new constitution provided for a constitutional monarchy with a bicameral parliament composed of the Senate (Γερουσία) and the Parliament (Βουλή).

First period of the Constitutional monarchy, 1863–1924

After the ousting of King Otto, elections were held to form the Second National Assembly [el], which effectively ran the country until the arrival of King George I in October 1863. The Assembly thereafter promulgated the Constitution of 1864 and dissolved itself on 16 November 1864. The new constitution was liberal, established the principle of popular sovereignty and defined the country's new form of government as a Constitutional monarchy with parliamentary democracy (βασιλευομένη δημοκρατία), but retained considerable executive powers for the king. The Senate was abolished, and a unicameral parliament (Βουλή) of 181 members with a four-year term was proclaimed as the country's sole legislative body.

The first decade was marked by frequent changes of government, especially due to the king's interference. A landmark was the adoption of the "dedilomeni principle", championed by Charilaos Trikoupis, in 1875, which forced the king to appoint only governments that commanded a parliamentary majority and had the "declared (dedilomeni) confidence of the parliament". The 1880s and 1890s were also marked by political instability. The Goudi coup of 1909 resulted in the arrival of Eleftherios Venizelos and the August 1910 elections for a Revisoniary Parliament. New elections for a new Revisoniary Parliament were held in November, and the Constitution of 1911 was promulgated in June 1911. Political upheaval in the form of the National Schism dominated Greek politics from 1915 on, resulting in the Asia Minor Disaster and the abolition of the monarchy in 1924.

Second Hellenic Republic, 1924–1935

The Fourth National Assembly [el], resulting from the December 1923 elections, declared the abolition of the monarchy and constituted itself as the Fourth Constitutional Assembly on 25 March 1924. It was abolished on 30 September 1925 after the coup d'état led by Theodoros Pangalos on 26 June 1925, and the first regular parliament of the Second Hellenic Republic came about only after Pangalos' fall, with the 1926 elections. The new parliament voted the Constitution of 1927, which also re-established the Senate, for which the first elections were held in 1929.

Second period of the Constitutional monarchy, 1946–1967

This includes the post-World War II period up to the establishment of the Greek military junta of 1967–1974.

Third Hellenic Republic, 1974 to the present

The fall of the junta brought about a major regime change (metapolitefsi), which included the abolition of the monarchy by referendum. The strong two-party system of PASOK and New Democracy made the parliamentary life of the Third Hellenic Republic the most regular in Greek political history, with the exception of the 1989–90 political crisis. After 2011, the prevailing political system was shattered through the effects of the prolonged Greek debt crisis, leading to the marginalization of PASOK and the election, for the first time, of a left-wing party, the Coalition of the Radical Left, to power in the January 2015 elections.
