called "Kapodistrias II" but eventually named the "Callicrates Project", was implemented in 2010; it further consolidated municipalities down to 370, and merged the country's 54 prefectures into 13 peripheries. The Callicratean municipalities were designed according to several guidelines; for example each island (except Crete) was formed into a single municipality, while the majority of small towns were incorporated so as to have an average municipal population of 25,000. The first prefectural elections took place in 1994; previously, prefects were executive appointees. Municipal elections were held since the formation of the modern Greek state, in the early 19th century. Local administrators elected in 2010, following the Callicrates reform, are to serve a "rump" 3.5-year term. Starting in 2014, peripheral and municipal elections are to be held every five years, concurrently with elections for the European Parliament. In all local elections, the winning candidacy list is guaranteed a minimum three-fifths majority in the respective councils.

The latest referendum was indeed concerning a matter of "national interest", in contrast to all the previous ones that concerned the form of government, specifically regarding the Greek monarchy. Previous referendums There were 7 referendums in Greece from 1920 to 1974. All but one had to do with the form of government, namely retention/reestablishment or abolition of the monarchy. The 1974 referendum resulted in confirming of the parliamentary republic. The only referendum not concerning only the form of government was the constitutional referendum in 1968 held by the military junta. There were no referendums in Greece between 1974 and 2014. In 2015, the Greeks voted no on the bailout proposed by the ECB and IMF, which was however rejected by the government.
