Constantine Hangerli (, Konstantinos Chatzeris; c. 1760 – 18 February 1799), also written as Constantin Hangerliu, was a Prince of Wallachia between 1797 and the time of his death. He was the brother of Alexander Hangerli, who served as Prince of Moldavia in 1807. Biography Early life and investiture As a Phanariote, Hangerli claimed heritage from the Byzantine family of the Palaiologos. He was married to Doamna Roxana, who survived his death. According to one account, the surname Hangerli () had been assigned to one of his ancestors by Sultan Mehmed IV, after allegedly saving his life by curing him of a potentially fatal illness. The name was based on the word , which was indicative of closeness to the Sultan's person. The Hangerlis were related to other high-ranking Greek families, including the Ypsilantis and the Mourousis. After serving as Dragoman of the Fleet, Constantine surprised foreign diplomats through his appointment to the throne in Bucharest, in competition with the much more prestigious Alexander Ypsilantis. He probably owed this rise to the influence of his friend and former associate, Kapudan Pasha Husein Küçük: the latter had been dispatched to quell the rebellion of Osman Pazvantoğlu in Rumelia, and requested that Wallachia be made secure through the investiture of a trustworthy prince. Hangerli reached Bucharest on 4 January 1798, breaking with local custom by entering the city area through Podul Mogoşoaiei, instead of Calea Şerban Vodă. Bucharesters believed this to be a bad omen, indicative of an "unwise rule". Like all Phanariotes, he stopped at Văcăreşti Monastery to prepare for the official inauguration. For unknown reasons, he stayed there for more than a month, before temporarily settling in the Saint Sava Monastery, where he remained until Curtea Nouă was completely repaired. "Hangerli's winter" and conflicts with Husein Küçük Hangerli increased taxes to a very high level; new fees were created, including a special one for widowers. These measures were prompted by the substantial demands of the Porte, who was faced with Pazvantoğlu's major military successes, as well as by the prince's wish to increase his own revenue. The taxation reached its peak with the re-introduction of the despised văcărit tax (per head of cattle owned), which had been dismissed for perpetuity by his predecessor, Constantine Mavrocordatos – Hangerli purchased the lifting of a curse on the latter (cast in 1763) from Gregory V, Patriarch of Constantinople. Despite this, the tax continued
