Austrian gold currency) in Wallachia and to 3,100 in Moldavia. Immediately afterward, Russia forcefully used its new prerogative. The deposition of Constantine Ypsilantis (in Wallachia) and Alexander Mourousis (in Moldavia) by Selim III, called on by French Empire's ambassador to the Ottoman Empire Horace Sébastiani (whose fears of pro−Russian conspiracies in Bucharest were partially confirmed), was the casus belli for the 1806–1812 conflict, and Russian general Mikhail Andreyevich Miloradovich swiftly reinstated Ypsilantis during his military expedition to Wallachia. Such gestures began a period of effective Russian supervision, culminating with the Organic Statute administration of the 1830s. The Danubian principalities grew in strategic importance with the Napoleonic Wars and the decline of the Ottoman Empire, as European states became interested in halting Russian southward expansion (which included the 1812 annexation of Bessarabia). New consulates in the two countries' capitals, ensuring the observation of developments in Russian−Ottoman relations, had an indirect impact on the local economy as rival diplomats began awarding protection and sudit status to merchants competing with local guilds. Nicholas I of Russia pressured Wallachia and Moldavia into granting constitutions (in 1831 and 1832, respectively) to weaken native rulers. The boyars began a petition campaign against the princes in power; addressed to the Porte and the Habsburg monarchy, they primarily demanded Russian supervision. Although they referred to incidents of corruption and misrule, the petitions indicate their signers' conservatism. The boyars tend to refer to (fictitious) "capitulations" which either principality would have signed with the Ottomans, demanding that rights guaranteed through them be restored. They viewed reform attempts by princes as illegitimate; in alternative proposals (usually in the form of constitutional projects), the boyars expressed desire for an aristocratic republic. Greek War of Independence and legacy The active part taken by Greek princes in revolts after 1820 and the disorder provoked by the Filiki Eteria (of which the Ghica, Văcărescu and Golescu families were active members after its uprising against the Ottoman Empire in Moldavia and Tudor Vladimirescu's Wallachian uprising) led to the disappearance of promotions from the Phanar community; the Greeks were no longer trusted by the Porte. Amid tense relations between boyars and princes, Vladimirescu's revolt was primarily the result of compromise between Oltenian pandurs and the regency of boyars attempting to block the ascension of Scarlat Callimachi (the last Phanariot ruler in Bucharest). Ioan Sturdza's rule in Moldavia and Grigore IV Ghica's in Wallachia are considered the first
