The uprising of 1821 was a social and political rebellion in Wallachia, which was at the time a tributary state of the Ottoman Empire. It originated as a movement against the Phanariote administration, with backing from the more conservative boyars, but mutated into an attempted removal of the boyar class. Though not directed against Ottoman rule, the revolt espoused an early version of Romanian nationalism, and is described by historians as the first major event of a national awakening. The revolutionary force was centered on a group of Pandur (light infantry) irregulars, whose leader was Tudor Vladimirescu. The center of the uprising was the Wallachian subregion of Oltenia, where Vladimirescu established his "Assembly of the People" in February.

From the beginning, Pandurs were joined by groups of Arnauts and by veterans of the Serbian Revolution. Although infused with anti-Hellenism, they collaborated with, and were infiltrated by, agents of the Filiki Eteria. Vladimirescu also cooperated with the Sacred Band of Alexander Ypsilantis, thereby contributing to the larger war of Greek independence. In conjunction with Ypsilantis' troops coming in from Moldavia, Vladimirescu managed to occupy Bucharest in March. Vladimirescu agreed to split the country with Ypsilantis, preserving control over Oltenia, Bucharest, and the southern half of Muntenia. The Pandurs' relationship with the Sacred Band degenerated rapidly, upon revelations that the Russian Empire had not validated Ypsilantis' expedition, and also over Vladimirescu's attempts to quell Eterist violence. Many of the Arnauts openly or covertly supported Ypsilantis, while others endorsed an independent warlord, Sava Fochianos.

Vladimirescu secretly negotiated an entente with the Ottomans, who ultimately invaded Wallachia in late April. The Pandurs withdrew toward Oltenia, which put them at odds with the Sacred Band. Vladimirescu's brutality alienated his own troops; in turn, this rift allowed the Greek revolutionaries to arrest and execute Vladimirescu, unopposed. The Oltenians scattered, though some Pandurs formed pockets of resistance, led by captains such as Dimitrie Macedonski and Ioan Solomon. They suffered clear defeat in their confrontation with the Ottoman Army. In June, Ypsilantis' force and its remaining Pandur allies were routed at Drăgășani. The uprising sparked a cycle of repressive terror, with a final episode in August, when Fochianos and his Arnauts were massacred in Bucharest.

The uprising of 1821 is widely seen as a failed or incomplete social revolution, with more far-reaching political and cultural implications. The Ottoman government registered its anti-Phanariote message, appointing an assimilated boyar, Grigore IV Ghica, as Prince of Wallachia. The ascent of nationalist boyars was enhanced during the Russian occupation of 1828, and cemented by a new constitutional arrangement, Regulamentul Organic. During this interval, survivors of the uprising split between those who supported this conservative establishment and those who favored liberal causes. The latter also helped preserve a heroic image of Vladimirescu, which was later also borrowed by agrarianists and left-wing activists.

Origins Phanariote crisis From the beginning of the 18th century, Wallachia and Moldavia (the Danubian Principalities) had been placed by the Sublime Porte under a regime of indirect rule through Phanariotes. This cluster of Greek and Hellenized families, and the associated Greek diaspora, were conspicuously present at all levels of government. At a more generalized level, the Phanariote era emphasized tensions between the boyars, Phanariote or not, and the peasant class. Though released from serfdom, Wallachian peasants were still required to provide for the boyars in corvées and tithes. Over the early 19th century, the rural economy was often paralyzed by peasant strikes, tax resistance, sabotage, or litigation.Djuvara, pp. 261–262 Additional pressures were created by Ottoman demands for the haraç and other fiscal duties, which the Phanariotes fulfilled through tax farming. "Excessive fiscal policies, dictated by both the Ottoman demands and the short span of reigns" meant that Phanariotes treated the principalities as "an actual tenancy."Iliescu & Miron, pp. 9–10 The national budget for 1819 was 5.9 million thaler, of which at least 2 million were taken by the Sublime Porte, 1.3 million went to the ruling family, and 2.4 supplied the bureaucracy.Djuvara, pp. 70–71 Although not at their highest historical level, Ottoman pressures had been steadily increasing since ca. 1800.Bogdan Murgescu, România și Europa. Acumularea decalajelor economice (1500–2010), pp. 32–37. Iași: Polirom, 2010.

Tax payers were additionally constrained by those boyars who obtained tax privileges or exemptions for themselves and their families. In 1819, from 194,000 families subject to taxation, 76,000 had been wholly or partly exempted.Djuvara, p. 70. See also Iliescu & Miron, p. 10 Tax farmers, in particular the Ispravnici, acted in an increasingly predatory manner, and, in various cases, tortured peasants into paying more than their share.Djuvara, pp. 73–74; Iorga (1921), pp. 326–327 and (1932), pp. 5–7 In the 1800s, a reformist Prince Constantine Ypsilantis sided with the peasants, cracking down on abuse and even threatening capital punishment; this episode failed to address the causes, and abuses continued to be recorded into the 1810s.Djuvara, pp. 73–74 Under constant fiscal pressure, many villagers resorted to selling their labor to boyars or to peasant entrepreneurs. According to a report by the Ispravnic of Gorj County, in 1819 migrant farmhands could barely cover their tax debt.Maciu, pp. 935–936

Under the Phanariote regime, the country had dissolved her levy army—though a core force had briefly reemerged under Nicholas Mavrogenes, who led a Wallachian peasant force into the Austro-Turkish War of 1788.Anton Caragea, "Fanarioții: vieți trăite sub semnul primejdiei. 'Grozăviile nebunului Mavrogheni'", in Magazin Istoric, November 2000, p. 70 Especially visible in Oltenia, the Pandurs traced their origins to the late 17th century, and had also functioned as a militia in 1718–1739, when Oltenia, or "Banat of Craiova", was a Habsburg territory. At times, they had been self-sustaining, with a lifestyle that bordered on hajduk brigandage.Ciobotea & Osiac, pp. 143–144 The Phanariotes' hold on the country was put into question by turmoil during the Napoleonic era, which resulted in some additional rearmament. In 1802, the threat of an invasion by Ottoman secessionist Osman Pazvantoğlu pushed Bucharest into a panic. At its height, the mercenary Sava Fochianos and his Arnauts denounced their contract and left the city defenseless.Djuvara, pp. 281–283. See also Maciu, p. 934 This embarrassment prompted Ypsilantis to form a small national contingent, comprising armed burghers and Pandurs who were trained by Western standards.Djuvara, pp. 283, 356; Vârtosu (1962), passim

Although approved by the Ottomans, this new militia was secretly also a component of Ypsilantis' plan to shake off Ottoman suzerainty with help from the Russian Empire. By August 1806, his alliance with Russia had been exposed, and he was forced to leave into exile.Djuvara, pp. 283–284, 295 The incident also sparked a six-year-long Russo-Turkish War. During this period, the Wallachian Pandurs, including a young Tudor Vladimirescu, acted as a unit of the Imperial Russian Army.Bogdan-Duică, p. 41; Cernatoni, pp. 40–41; Ciobotea & Osiac, pp. 143–146; Dieaconu, pp. 45, 47; Djuvara, pp. 284–286, 297, 299, 356; Finlay, p. 123; Georgescu, p. 100; Iliescu & Miron, pp. 12–13; Iorga (1921), pp. XI, 3–4, 189, 232 and (1932), p. 54; Iscru, pp. 678, 680; Lăcusteanu & Crutzescu, p. 37; Maciu, pp. 936, 939; Nistor, p. 889; Rizos-Nerulos, p. 284; Vârtosu (1945), p. 345 and (1962), pp. 530, 545; Vianu & Iancovici, pp. 75–77 Under Russian occupation, the Greek–Wallachian rebel Nicolae Pangal issued several manifestos which, as noted by historian Emil Vârtosu, resembled later appeals by Vladimirescu.Vârtosu (1962), pp. 533–535, 545

Hostilities were eventually suspended by the Treaty of Bucharest, hurried by Russia's need to defend herself against the French;Djuvara, pp. 288–289 Ottoman rule in Wallachia and Moldavia was again consolidated with Russia focused on winning a war in Central Europe. The new Phanariote Prince was John Caradja, whose reign saw an upsurge in tax resistance and hajduk gang activity. In Bucharest, the epidemic known as Caragea's plague was an opportunity for marauding gangs of outlaws, who confused the authorities by dressing up as undertakers.Djuvara, pp. 293–295 Rebellious activity peaked in Oltenia, where hajduks were organized by Iancu Jianu, a boyar's son, who frustrated all of Caradja's attempts at restoring order.Djuvara, p. 291 However, the Pandurs were divided. In 1814, some joined a raid by pirates from Ada Kaleh, storming through Mehedinți County and Gorj, though they later sought forgiveness from Vladimirescu.Maciu, pp. 936, 940. See also Iscru, pp. 679–680 The latter had sided with the Caradja regime, but still intervened on their behalf.Cernatoni, p. 42; Maciu, p. 936

Preparation As a result of 1814 riots, tax privileges for the Pandurs were suspended, and they were demoted to the position of a militia assisting the Ispravnici.Maciu, p. 936 In 1818, Caradja abandoned his throne and fled Wallachia, leaving Sultan Mahmud II to appoint an elderly loyalist, Alexandros Soutzos. His decision also specified that only four Phanariote families would be eligible for the crowns of either Wallachia and Moldavia: Callimachi, Mourouzis, and two lines of the Soutzos.Djuvara, pp. 295–296 Upon entering Bucharest, the new Prince inaugurated a regime of institutional abuse. In April 1819, the attempt to put pressure on the peasantry sparked a riot at Islaz.Cernatoni, p. 42. See also Popp, p. XII In one especially controversial writ of 1820, Soutzos ruled that the city of Târgoviște was not mortmain, and proclaimed it his family's property. This edict resulted sparked a burgher revolt, during which cadastre officials were attacked and chased out of Târgoviște.Djuvara, p. 191 Though he still favored the Arnauts,Nistor, p. 887 Soutzos revised anti-Pandur persecution, restoring their role in the army and placing them under the command of a Romanian, Ioan Solomon.Ciobotea & Osiac, p. 146 His tensions with the Arnauts resulted in a standoff with the mercenaries, who barricaded themselves inside Sinaia Monastery.Dieaconu, p. 46 However, Pandur Mihai Cioranu contends, Wallachia "swarmed with Greeks as never before", with every military commission set aside to serve "the Prince and his Greeks".Iorga (1921), pp. 228–229

Soutzos' other conflict was with the lesser Phanariotes, who were now won over by Greek nationalism. In 1820, Alexander Ypsilantis, son of Prince Constantine, united the various branches of the Filiki Eteria, a Greek revolutionary organization, and began preparing a massive anti-Ottoman revolt from the Russian port city of Odessa. This society had already managed to enlist in its ranks some preeminent Wallachian boyars: allegedly, its first recruits included Alecu Filipescu-Vulpea, joined later by Grigore Brâncoveanu.Vianu & Iancovici, pp. 74–75. See also Iliescu & Miron, p. 12 According to one account, the Eterists also invited Soutzos to join the conspiracy, but he refused.Djuvara, p. 296; Iorga (1921), pp. 353–354 He died suddenly on January 19, 1821, prompting speculation that he had been poisoned by Ypsilantis' partisans.Djuvara, p. 296; Finlay, p. 118; Georgescu, p. 97; Iorga (1921), pp. 231, 353–354 and (1932), pp. 24, 25; Lăcusteanu & Crutzescu, pp. 37, 227; Papacostea, p. 10; Potra (1963), p. 64
