The Lordship of Chios was a short-lived autonomous lordship run by the Genoese Zaccaria family. Its core was the eastern Aegean island of Chios, and in its height it encompassed a number of other islands off the shore of Asia Minor. Although theoretically a vassal of the Byzantine Empire, the Zaccaria ruled the island as a practically independent domain from its capture in 1304 until the Greek-Byzantines recovered it, with the support of the local Greek population, in 1329. The island would return to Genoese control in 1346 under the Maona of Chios and Phocaea.

The Thessaloniki metropolitan area or larger urban zone (LUZ) is the complete area covered and directly influenced by Thessaloniki. The metropolitan area traditionally consisted of the municipality of Thessaloniki and its immediate surroundings, what is today referred to as the Thessaloniki urban area. However, since the mid to late 1990s, the areas surrounding the urban area, have succumbed to urban sprawl and what used to be agrarian communities are rapidly urbanizing and being developed into suburbs or exurbs. This is creating new problems for a region already facing issues such as pollution, traffic congestion and social ills. Thessalonians usually refer to 6 municipalities and 1 municipal unit as the "City of Thessaloniki" (or the Thessaloniki urban area); this is the contiguous densely built-up urban area of the city. However, the metropolitan area also includes the city's immediate surroundings, adjacent zone of influence and its low to medium density suburbs that surround the densely built-up urban area. Thessaloniki spreads over 30 kilometres (19 mi) from Oraiokastro in the north to Thermi in the south.

The Thessaloniki History Centre was established by the Municipal Council of Thessaloniki, the largest city in northern Greece, in 1983, and has occupied its present premises (the gift of Anastasios and Ioulia Billis) in Ippodromiou Square since 1995. The purpose of the centre is to collect, rescue, record, and preserve printed, written, and audio-visual material relating to the history of the city and wider area of Thessaloniki. It also promotes and facilitates historical research relating to Thessaloniki and seeks to rouse the interest of foreigners in the modern city and its historical past. It is governed by an Advisory Committee made up of distinguished scholars. The centre has preserved the Municipal Archive and is classifying it, and has also acquired a number of private archives by gift or purchase. It has built up a history library, comprising 4,000 books, 3,000 photographs, 5,000 postcards, posters, videocassettes, and historical maps. It publishes its research work with periodic exhibitions illustrating the historical continuity of Thessaloniki and the wider area of Macedonia, organizes conferences and lecture series, and hosts events organized by other institutions with related interests. The History Centre also produces a scholarly journal titled Thessaloniki, containing original scholarly articles, and books on Thessaloniki and its history. The Centre intends to convert the city’s archives into electronic form to make them more accessible to researchers, and to link up to the Internet so that information and knowledge about the history of Thessaloniki will be accessible to a wider public.
