National Party[1] (Greek, Modern (1453-);: Εθνικόν Κόμμα, Ethnikon Komma;) or Diligiannis' Komma was a conservative Greek political party from 1883 to 1916 founded by Theodoros Diligiannis[2] It was opposed primarily by the New Party of Charilaos Trikoupis.
The National Party was formed after the previous major-power client political parties, the Russian Party, English Party and the French Party, ceased to be factors after the reign of King Otto in 1865. Upon the death of Alexandros Koumoundouros on 26 February 1883 - the leadership of his large parliamentary group passed to Theodoros Diligiannis. This parliamentary group evolved into a party, the so called National Party. Theodoros Deligiannis, famously stated that he "was against everything Trikoupis was for".[2] Throughout the 1880s and 1890s, Greece developed a stable two-party system with the premiership alternating between Deligiannis and Trikoupis. Since 1885, bipartisanship has been an integral part of the political life of the Greek electorate.
Deligiannis was assassinated in 1905 by a gambler who was outraged at Deligiannis's proposal to curtail gambling. In 1905, after the assassination of Theodore Deligiannis, Kyriakoulis Mavromichalis became the leader of the party. After his death in 1916, the party was dissolved.
