Giovanni Querini was a 13th-century Venetian nobleman and administrator.
Giovanni Querini is first attested in 1204 in Venice. [1] In 1225, he was ducal councillor, and in 1226 he took up service under the Latin Emperor, Robert of Courtenay, though not before taking an oath to not do so against Venetian interests. [1] He was thus a natural choice to become Venetian Podestà of Constantinople, likely after Emperor Robert died in January 1228. [2] His term of office was nevertheless brief, as he was replaced in spring 1229 by Romeo Querini. [3] He is finally attested as ducal councillor in Venice in 1231. [3]
Jacopo Tiepolo, also known as Giacomo Tiepolo, was Doge of Venice from 1229 to 1249. He had previously served as the first Venetian Duke of Crete, and two terms as Podestà of Constantinople, twice as governor of Treviso, and three times as ambassador to the Holy See. His dogate was marked by major domestic reforms, including the codification of civil law and the establishment of the Venetian Senate, but also against a mounting conflict with Emperor Frederick II, which broke into open war from 1237 to 1245.
The Partitio terrarum imperii Romaniae, or Partitio regni Graeci, was a treaty signed among the crusaders after the sack of the Byzantine capital, Constantinople, by the Fourth Crusade in 1204. It established the Latin Empire and arranged the nominal partition of the Byzantine territory among the participants of the Crusade, with the Republic of Venice being the greatest titular beneficiary. However, because the crusaders did not in fact control most of the Empire, local Byzantine Greek nobles established a number of Byzantine successor kingdoms. As a result, much of the crusaders' declared division of the Empire amongst themselves could never be implemented. The Latin Empire established by the treaty would last until 1261, when the Empire of Nicaea reconquered Constantinople, re-establishing the Byzantine Empire. The various crusader principalities in southern Greece and the Aegean archipelago would last much longer, until they were conquered by the Ottomans in the 14th and 15th centuries.
The Podestà of Constantinople was the official in charge of Venetian possessions in the Latin Empire and the Venetian quarter of Constantinople during the 13th century. Nominally a vassal to the Latin Emperor, the Podestà functioned as a ruler in his own right, and answered to the Doge of Venice. The podestà was also officially known as Governor of One-Fourth and One-Half of the Empire of Romania and was entitled to wearing the crimson buskins as the emperors.
The Battle of Constantinople was a naval battle between the fleets of the Empire of Nicaea and the Republic of Venice that occurred in May–June 1241 near Constantinople.
Marco Gradenigo was a 13th-century Venetian nobleman, senior provincial administrator in the Venetian overseas empire and a military commander. He was involved in three major conflicts: the War of the Euboeote Succession, where Gradenigo organized a league of the lords of Latin Greece against the Principality of Achaea; the defence of the Latin Empire against the Empire of Nicaea, which failed with the Reconquest of Constantinople by the Nicaeans during Gradenigo's tenure as Podestà of Constantinople; and the naval operations of the War of Saint Sabas against the Republic of Genoa.
