Matei returned to Bucharest alongside a large retinue of
Ottoman Greeks. He only reached his capital in late 1752, as one of the few princes of that decade to begin his reign in autumn or winter. A contemporary account dates his arrival to October 7261
Anno Mundi. as does an unsigned Greek ledger. Bassa Mihali never followed, but continued to support his son-in-law from Istanbul. Instead, the new monarch was more directly advised by two members of the
Soutzos family (a newly promoted section of the Phanariote class), as well as by the acting
Spatharios, Nicolae Roset, who had married Bassa Mihali's other daughter. The prince is also known to have favored regular immigrants such as Costin Ologul of
Metsovo. The latter, a victim of
frostbite, had had had his toes amputated at
Colțea Hospital (the first operation known to have been performed there), and was granted a farm carved out of the prince's estate. Matei also banished the leader of the boyar opposition,
Pârvu Cantacuzino, who was banished from Wallachia "for a full year", and then similarly retaliated against Pârvu's brother and political ally, Mihai. Matei intervened to strengthen some of Grigore's core policies. The Russian surveyor Friedrich Wilhelm Bauer observed that Ghica junior had nominally reduced the fiscal burdens, or
sferturi, in the form introduced by Grigore, but in tandem had increased the number of payments owed by each subjects. In two writs of October 1752, the young monarch applied his father's philosophy in education, which was to have schools of the
Wallachian Orthodox Church financed by a tax levied on parish priests. Also like his father, Matei was interested in colonizing the outskirts of Bucharest, donating for the construction of a
guild church in Broștenilor
mahala, south of Curtea Veche. Finding that
Giulești was irresistibly beautiful, he commissioned a
pavilion, which replaced one constructed by Grigore. The building does not survive, but it is presumed by architects to have been rather grandiose, in the style of Istanbul's
yalı dwellings. Its construction was supervised by Dumitraki Soutzos, who was the acting
Aga (police superintendent). In January 1753, Matei honored "the blessed Grigore Ghica" by resuming his donations to the
Monastery of Saint John the Theologian on
Patmos. These were set a sum of 30
Thaler, reserved from the Wallachian salt mines and paid annually. He similarly ensured the upkeep of
Pantelimon Hospital, with an annual grant of 2,500 Thaler, all obtained from the mining town of
Ocnele Mari. Like his father and his brother, Matei had his portrait painted as a patron of charities (it survived as a modern copy at
Eforia Spitalelor Civile). Matei immediately alienated the local boyardom by promoting his Greek proteges as boyars in exchange for modest bribes, said to have at least once included "some yards of cloth"; over a few days, he created thirty
Stolnici, twenty
Paharnici, and fifty
Serdari. The opposition organized in a form that, as Panait reports, was unprecedented, since it required a "
collaboration of all the classes" (though still "lacking a clear platform"). This coalition sent
Medelnicer Ștefanachi, who had been sidelined by Ghica, to approach the Sultan in Istanbul. He prostrated before Mahmud in the courtyard of
Eyüp Sultan Mosque, handing him a supplication of the native boyars. Matei's indifference to local custom was also rated as insulting by the Wallachian Church, whose Metropolitan, Neofit Cretanul, agreed to preside upon the boyars' anti-Phanariote movement (despite being a foreigner himself). In the Ghica family chronicles, it is alleged that Neofit, an ailing man, had been fed "strong medicine" by his bribed-off physician, making him "lose his mind" ahead of joining the revolt. An Ottoman official, Hagi Mustafa, was dispatched to Bucharest, where, on 21 May 1753, he watched on as a mass of boyars and commoners marched in protest before him. This moment is seen by Panait as highly disruptive for the established order, since "the streets of the city were under the authority of the popular masses", leading boyars such as Barbu and Ștefan Văcărescu to flee from Bucharest. Mahmud decided to punish men involved on both sides of the controversy: in June 1753, Bassa Mihali was sent into exile alongside Roset, Ștefanachi, and the rebel Constantin Dudescu, just as Matei was ordered to take up the Moldavian throne—whose previous holder,
Constantin Racoviță, had similarly alienated his subjects. In a historically unprecedented move, Racoviță took the throne in Bucharest, where he was met with other forms of sabotage and opposition. Neofit is believed to have died of his ailment on the exact day that Matei was leaving Bucharest. According to the historian Jean-Paul Besse, the prelate had in fact been poisoned by the disgruntled and outgoing monarch. The exact date of these twinned events is unknown, but the exchange of thrones is certain to have occurred before 3 July. ==Moldavian rule==
