then Moldavian Prince Michael Soutzos (see Greek War of Independence). However, this coincided with Russian reaction against Greek rebellion, with the Russian army entering Moldavia and enforcing Holy Alliance policies. Ypsilanti's army headed south, reaching Pandur-occupied Bucharest. Tudor's actions in the meanwhile had destroyed his alliance to local boyars. He had started wearing the kalpak (a tall, cylindrical, black leather hat; see Ottoman Clothing) reserved for the Prince, and demanded to be addressed as Domn ("Master", "Prince"; cf. Domnitor) - moving away from subordination to the landowners' cause. The meeting between Ypsilanti and Tudor brought a new compromise. Tudor considered himself liberated from the provisions of the January agreement, as Russia was now an enemy of the Etaireía; Ypsilanti tried to persuade him that Russian support was still possible. The country was divided into a Greek administration and a Wallachian one, with Tudor's declaring itself neutral in the face of large Ottoman armies preparing to cross the north of the Danube. Ottoman actions had been prompted by Russian threat of intervention in Wallachia. Tudor's army retreated towards in Oltenia in May, as the Ottomans occupied Bucharest without meeting resistance. Tudor was no longer capable of maintaining the discipline and cohesion of his own troops, some of whom had resorted to robbery. In an attempt to ensure discipline, he imposed hangings of those found guilty. In the meantime, Etaireía members, led by Alexander Ypsilantis developed a plot to remove Tudor. Following treason, Tudor was arrested in on 21 May. On the night of 27 to 28 May, following accusations of collaboration with the Ottomans against Etaireía, he was tortured and killed by Etaireía in Târgoviște, his mutilated body being thrown into a cesspit. Tudor's collaboration with the Ottomans was never confirmed. The Etaireía did not succeed in its goal to assume command of Vladimirescu's army: most of it disbanded on the spot. Legacy Tudor's rebellion ensured that Wallachia would stay under military occupation. Although the situation was stabilized by August, Ottoman troops remained until 1826. However, as they could no longer trust Phanariote rule in the face of its infiltration by Greek nationalism (Ypsilanti himself came from a Phanariote family - see Alexander Ypsilanti, his grandfather, and Constantine Ypsilanti, his father), the Ottomans returned the two Principalities to rule by and through locals (in 1822): Grigore IV Ghica in Wallachia, Ioan Sturdza (Ioniţă Sandu Sturdza) in Moldavia.
