Nicholas Mavrocordatos (Greek: Νικόλαος Μαυροκορδάτος, Romanian: Nicolae Mavrocordat; May 3, 1670 in Constantinople – September 3, 1730 in Bucharest) was a Greek member of the Mavrocordatos family, Grand Dragoman to the Divan (1697), and consequently the first Phanariote Hospodar of the Danubian Principalities - Prince of Moldavia, and Prince of Wallachia (both on two separate occasions). He was succeeded as Grand Dragoman (1709) by his brother John Mavrocordato (Ioan), who was for a short while hospodar in both Wallachia and Moldavia.
Deposed as Grand Dragoman in Moldavia in favor of Dimitrie Cantemir, owing to the suspicions of his Ottoman overlord, Sultan Ahmed III, he was restored in 1711 (after Cantemir's rebellion during the Russo-Turkish War of 1710-1711), and, for this second rule, is considered the first in a line of Phanariotes in Moldavia (indicating that the election by the traditional Moldavian council of boyars was no longer enforced).
Soon afterwards, he was replaced by Mihai Racoviță and became ruler of Wallachia, being thus the first Phanariote in that country – after the Porte decided to regulate the same system following the rebellion of Ștefan Cantacuzino. According to Anton Maria Del Chiaro, the Florentine secretary to Constantin Brâncoveanu (predecessor and rival of Ștefan Cantacuzino), Mavrocordatos tortured and otherwise persecuted Wallachian boyars who had supported the Cantacuzinos, and also ordered the execution of Ștefan's son. He was also noted for awarding tax exemptions to the majority of high-ranking boyars, as one of the first rulers to concede to the growth of monetary economy and the decay of manorialism.
