With origins in Cyprus and Byzantium, the family achieved levels of wealth, prominence, and aristocracy over the centuries in branches found across modern Greece, Italy, Croatia, Serbia, Albania, Romania, France, and Brazil.

[1][2] The Calogerà are studied in numerous registers of nobility, including the Libro d'Oro of Corfu, Wappenbuch des Königreichs Dalmatien (1873),[3] Livre d'Or de la Noblesse Ionienne (1925), and Heraldika Shqiptare (2000), among others.

Thus the early 17th-century cartographer Vincenzo Coronelli included the following information in Biblioteca Universale Sacro-Profana: [...] Many succeeding emperors tried to take back [Crete from the Muslim rulers]; but it was always in vain, and with losses.

[4] It is likely that Coronelli’s inclusion of the Calogerà in the 12 noble families of Crete, or archontopoula, is based on Andrea Corner's (1547 – c. 1616) Storia di Candia, the first literary work to deal exclusively with the island’s history.

In 1431, John Calogerà assumed the post of adviser to Duke Acciaoli in Athens during Attica's period of short-lived sovereignty from [ Catalan rule in] southern Italy.

In 1499, Ambassador Matheus Calogerà was sent to Venice on behalf of the Rector of Zante in order to obtain the constitution of [Venetian] territorial property from the Senate.

Several members of the family entered the religious orders; innumerable others were distinguished in war and rendered valuable services to the Republic of Venice, for which they were recognized in various decrees by the Senate and the Doges.

In the Church of Saint Anthony [it; fr] in Venice, one finds, surmounted by his coat-of-arms, the tomb of Demetrio Calogerà, who died in 1682 and who was a direct descendant of the main branch of Corfu.

1436 - d. 1506) writes the following selection in Dell' Historia Venitiana: [...] But the Calotheri and Anatolici were banished, even if they prided themselves on their ancient parentado[7] to the Emperor of Greece.

[...] A Calógeras shines in the hagiological calendar as early as the fifth century, extolling excellent virtues, religious struggles, and the evolution of spiritual postulates in the person of a saint.

[Members of this family] sparkled spirits and cultures in the likes of Draco Calógeras, Dino and Francesco, and Zorzi and Antonio, at the head of events in the greater history of the Republic of Venice that would alter the organization and political distribution of the Mediterranean world.

For this reason, the arms of Demetrius Calógeras would be featured in the golden and blue panel of the Church of Saint Anthony [it; fr] in Venice; John Paul would glow in the military history of Bergamo; Spiridion would die as Admiral of the Arsenal of Corfu in the eighteenth century; and Marco Calógeras would die as Bishop of Cattaro [sic] in Dalmatia in the mid-nineteenth century.

Theologians, writers, poets, philologists, philosophers, admirals, generals, sociologists, tribunes, jurists, doctors, and engineers all appear in great numbers in this immense family, which, ever and always illustrious over the centuries, finally arrived in Brazil in 1841 in the person of João Batista Calógeras (grandfather of João Pandiá Calógeras).

João Batista, who was a close friend of the Baron de Lafitte—a celebrated banker and minister of King Louis Philippe—lead a financial initiative [on behalf of] that famous man of pecunia [in Brazil].

[9] Giovan Battista di Crollalanza's masterpiece, Dizionario Storico-Blasonico delle Famiglie Nobili e Notabili Italiane, Estinte e Fiorenti (1886), describes the Venetian- and Dalmatian branches of the family: CALOGERÀ of Venice.

⁠— ARMS: Of azure [background], a silver, beamless anchor, its shaft accented with a green cedar branch bearing a single, yellow fruit on its left side; all accompanied at the top by a star of eight golden rays.

[...] Descendants of the family distinguished themselves throughout the period of Ottoman rule as elders (proestoi), notaries and men of letters, teachers, et cetera.

Ioannis Benizelos (c. 1735 – 1807) studied at the Common School of Athens, married Maria, daughter of Dimitrios Kalogeras (who was also from a noble family of the city and was an elder).

In Biskup Marko Kalogjera o 120. obljetnici smrti: Zbornik radova znanstvenog skupa održanog u prosincu 2008. u Blatu, Svezak 1.

Moreover, the family has produced pedagogues, teachers, bishops, and abbots, and among its members we find excellent musicologists and writers as well as merchants and industrialists.

In the early 18th century, Don Francesco Calogerà, warden of the Venetian state hospital in Hvar, married the daughter of goldsmith Steffano Cortino, and their son, Steffano Calogerà, became the progenitor of the Kalogjera family of Korčula and the first to adopt the double-barreled nickname of Kalogjera Zlatar, meaning goldsmith.

[16] In the academic journal Provijesni Prilozi, Dr. Ivan Mirnik [hr], archaeologist and numismatist at the Archaeological Museum in Zagreb, describes the Calogerà family⁠—spelled Kalogjera or Kalođera in modern Croatian⁠—as one of roughly 100 Dalmatian noble families featuring the "Star of Krk" in their coats of arms.

"It is with great regret that I received the news of the death of Dr. Nikica Kalogjera, an artist of exceptional creative energy, who remained faithful to music for all of his interesting life," reads the telegram of condolences from President Mesić.

"I received, with sadness, the news of the death of Nikica Kalogjera, a physician who so bravely and successfully assumed music as his chosen profession.

This coat of arms is in the archives of the Corfu Museum, and a stone version exists in the lobby of the University of Padua just to the left of the entrance.
