While many of his relatives had occupied the throne in both Wallachia and Moldavia as Phanariotes, the regime change after the Greek War of Independence, Tudor Vladimirescu's 1821 uprising and the Philikí Etaireía's brief rule in the two Danubian Principalities, led to Grigore IV being considered the first in a succession of non-Phanariote rulers. The elections for Prince in the Divan, although prescribed by the Akkerman Convention of 1826, were not to be organized, due mainly to precipitating events. As a Prince, Grigore watched after the development of agriculture in his region.
