Ioannis Kapodistrias in the context of National Library of Greece

Kapodistrias reform (Greek: Σχέδιο Καποδίστριας, "Kapodistrias Plan") is the common name of law 2539 of Greece, which reorganised the country's administrative divisions. The law, named after 19th-century Greek statesman (Ioannis Kapodistrias), passed the Hellenic Parliament in 1997, and was implemented in 1998. The administrative system was changed again at the 2010 Kallikratis reform.

A regency council (Greek: Αντιβασιλεία, German: Regentschaft) ruled the Kingdom of Greece in 1833–1835, during the minority of King Otto. The council was appointed by Otto's father, King Ludwig I of Bavaria, and comprised three men: Josef Ludwig von Armansperg, Georg Ludwig von Maurer, and Carl Wilhelm von Heideck. The first period of the regency saw major reforms in administration, including the establishment of an autocephalous Church of Greece. The regency's authoritarianism and distrust of the Greek political parties, especially the Russian Party, which was associated with the period of Governor Ioannis Kapodistrias and was particularly opposed to the Church reforms, led to a quick eroding of its popularity. Armansperg was the council's chairman, but increasingly clashed with the other two regents, who in turn aligned with the French Party under Ioannis Kolettis. The main domestic event of the early period was the arrest and sham trial of Theodoros Kolokotronis, a hero of the Greek War of Independence and the de facto leader of the Russian Party, in 1834. This rallied the opposition against the regency, helped provoke a major uprising in the Mani Peninsula, and fatally undermined the prestige of Maurer and Heideck versus Armansperg. The conflict was resolved in Armansperg's favour in July 1834, when Maurer was replaced by Egid von Kobell (de). Following Otto's coming of age in June 1835, the council was dissolved, but Armansperg remained in charge of the government as Prime Minister.
