1768 The confederation, encouraged and aided by Roman Catholic France and Austria, declared war on Russia. The Confederates began operating in Lithuania, although after early successes that direction too met with failures, with defeats at
Białystok on 16 July and Orzechowo on 13 September 1769. Perhaps the last stronghold of the confederates was in the monastery in
Zagórz, which fell only on 28 November 1772. In the end, the Bar Confederation was defeated, with its members either fleeing abroad or being
deported to Siberia, Volga region, Urals by the Russians. In the meantime, taking advantage of the confusion in the Commonwealth, already by 1769–71, both Austria and Prussia had taken over some of its border territories, with Austria taking
Szepes County in 1769–1770 and Prussia incorporating
Lauenburg and Bütow. On 19 February 1772, the agreement of partition was signed in
Vienna. A previous secret agreement between Prussia and Russia had been made in
Saint Petersburg on 6 February 1772. Early in August, Russian, Prussian, and Austrian troops fighting the Bar confederation in the Commonwealth occupied the provinces agreed upon among themselves. On 5 August, the three parties issued a manifesto about their respective territorial gains on the Commonwealth's expense. Bar Confederates taken as prisoners by the Russians, together with their families, formed the first major group of Poles and Lithuanians exiled to Siberia (
sybirak). It is estimated that about 5,000 former confederates were sent there.
Russia organized 3
concentration camps in Polish–Lithuanian Commonwealth for Polish captives, where these concentrated persons have been waiting for their deportation there.
International situation after the defeat of Bar confederation and its Ottoman allies Around mid-18th century the European
balance of power shifted, with Russian victories against the
Ottomans in the
Russo-Turkish War (1768–1774) strengthening Russia and endangering
Habsburg interests in that region (particularly in
Moldavia and
Wallachia). At that point Habsburg Austria started to consider waging a war against Russia. France, friendly towards both Prussia and Austria, suggested a series of territorial adjustments, in which Austria would be compensated by parts of
Prussian Silesia, and
Prussia in turn would receive Polish Ermland (
Warmia) and parts of the Polish
fief,
Duchy of Courland and Semigalliaalready under
Baltic German hegemony. King Frederick II of Prussia had no intention of giving up Silesia gained recently in the
Silesian Wars. He was interested in finding a peaceful solution –
his alliance with Russia would draw him into a potential war with Austria, and the Seven Years' War had left Austria's treasury and army weakened. He was also interested in protecting the weakening Ottoman Empire, which could be advantageously utilized in the event of a Prussian war either with Russia or Austria. Frederick's brother,
Prince Henry, spent the winter of 1770–71 as a representative of the Prussian court at Saint Petersburg. As Austria had annexed 13 towns in the Hungarian Szepes county in 1769, violating the
Treaty of Lubowla, Catherine II of Russia and her advisor General
Ivan Chernyshyov suggested to Henry that Prussia claim some Polish land, such as Ermland. After Henry informed him of the proposal, Frederick suggested a partition of the Polish borderlands by Austria, Prussia, and Russia, with the largest share going to Austria. Thus Frederick attempted to encourage Russia to direct its expansion towards weak and non-functional Polish–Lithuanian Commonwealth instead of the Ottomans. Russia considered the weak Poland–Lithuania as its protectorate for a few decades already since the
Silent Sejm. Poland–Lithuania was devastated by a civil war in which the Bar Confederation's forces attempted to disrupt Russian control. The recent Koliivshchyna peasant and Cossack uprising in Ukraine also weakened Polish–Lithuanian position. Further, the Russian-supported king of Poland, Stanislaus Augustus, was seen as both weak and too independent-minded. Eventually the Russian court decided that Poland–Lithuania's usefulness as a protectorate had lessened. The three powers officially justified their actions as compensation for dealing with troublesome neighbor and restoring order to Polish anarchy, for which the Bar Confederation provided a convenient excuse. All three were interested in territorial gains. After Russia occupied the
Danubian Principalities, Henry convinced Frederick and Archduchess
Maria Theresa of Austria that the balance of power would be maintained by a tripartite division of the Polish–Lithuanian Commonwealth instead of Russia taking land from the Ottomans. Under pressure from Prussia, which for a long time wanted to annex the northern Polish province of
Royal Prussia, the three powers agreed on the First Partition of Poland–Lithuania. This was in light of the possible Austrian-Ottoman-Bar confederation alliance with only token objections from Austria, which would have instead preferred to receive more Ottoman territories in the
Balkans, a region which for a long time had been coveted by the Habsburgs, including Bukovina. The Russians also withdrew from
Moldavia and Wallachia away from the Austrian border. ==Legacy==
