Citing Vasile's reliance on his Greek and Levantine retinue, as well as an alleged dishonoring of his wife by the Prince, he allied himself with Wallachian Prince Matei Basarab and Transylvanian ruler George II Rákóczi. He managed to expel Vasile Lupu, but the latter was helped to regain his position by Bohdan Khmelnytsky's force (under the command of the Hetman's son Tymofiy/Tymish), sent to Moldavia to depose him. Tymish and Lupu followed him to Wallachia, but their armies were crushed by Matei Basarab in the Battle of Finta. Gheorghe Ştefan regained Iași and remained on the throne, making sure that the Ottoman power was appeased - he bought his power in Constantinople, having to increase taxes in order to cover the expenses, and pay for the maintenance of his large mercenary force.
