Kleisthenis I Programme in the context of "Administrative divisions of Greece"

The municipalities of Greece (Greek: δήμοι, romanized: dímoi [ˈðimi], in singular case Greek: δήμος, romanized: dímos) are the lowest level of government within the organizational structure of the state. As of 2021, there are 332 municipalities, further divided into 1036 municipal units and 6136 communities. The new municipalities may be subdivided into municipal units (δημοτικές ενότητες, dimotikés enótites), consisting of the pre-Kallikratis municipalities. These were further subdivided into municipal communities (δημοτικές κοινότητες, dimotikés koinótites) and local communities (τοπικές κοινότητες, topikés koinótites) according to population, but are simply named communities (κοινότητες, koinótites) since the entry into force of the Kleisthenis I Programme on 1 September 2019.

Municipal units and communities do not have legal personality and are not self-governing entities. Municipal units function as electoral districts for their municipalities, but their territories have no associated councils of their own. Communities have popularly elected councils which their respective municipalities are obligated to fund, but these councils are only advisory in nature.

The Kallikratis Programme (Greek: Πρόγραμμα Καλλικράτης, romanized: Prógramma Kallikrátis) is the common name of Greek law 3852/2010 of 2010, a major administrative reform in Greece. It brought about the second major reform of the country's administrative divisions following the 1997 Kapodistrias reform.

Named after ancient Greek architect Callicrates, the programme was presented by the socialist Papandreou cabinet and was adopted by the Hellenic Parliament in May 2010. The programme's implementation started with the November 2010 local elections, and was completed by January 2011. It was amended by the Kleisthenis I Programme (Law 4555/2018), which was adopted in July 2018 and implemented in September 2019.

Ereikoussa (Greek: Ερείκουσα) is an island and a former community of the Ionian Islands, Greece. It is one of the Diapontian Islands; an island complex to the northwest of Corfu. Since the 2019 local government reform it is part of the municipality of Central Corfu and Diapontian Islands, of which it is a municipal unit. It is located off the northwestern coast of the island of Corfu, and is almost equidistant from Corfu to the southeast, Mathraki to the southwest, and Othonoi to the west. Its population was 447 in the 2021 census, and its land area is 3.65 square kilometres (1 sq mi). The municipal unit has an area of 4.449 km. It has six settlements; the main one is Porto (Πόρτο), which is also where the only port is located. The island has dense vegetation and three beaches; Porto (Πόρτο), Bragini (Μπραγκίνι), and Fiki (Φύκι). The name Ereikoussa derives from the plant ereíki (ερείκη), which can be found throughout the island.
