Treaty of the Three Black Eagles

The three powers agreed that they would oppose another candidate from the House of Wettin as well as the candidacy of the pro-French Pole Stanisław Leszczyński, the father-in-law of Louis XV.

[5] The agreement had provisions for all three powers to agree that it was in their best interest that their common neighbour, the Polish–Lithuanian Commonwealth, did not undertake any reforms that might strengthen it[6] and for its elected monarch to be friendly towards them.

[2] In addition to the obvious, increasing the influence of the three powers over the Commonwealth, Austria and Russia also discreetly wanted to reduce the possibility of a French-Prussian-Saxon alliance.

[8] Austria received a promise that as king, Frederick Augustus would both renounce any claim to the Austrian succession and respect the Pragmatic Sanction of 1713.

[2][11] Diplomatic promises[2] and the arrival of Russian troops outside Warsaw on 20 September[8] caused a "rump" group, led by Michael Wisniowiecki (Great Chancellor of Lithuania) and Teodor Lubomirski (governor of Kraków) together with the Bishop of Poznań (Stanisław Józef Hozjusz) and the Bishop of Kraków (Jan Aleksander Lipski) to decamp to another Warsaw suburb, where they held a new election, under the protection of the Russian troops, picking Frederick Augustus II of Saxony, who became Augustus III of Poland.

[3] In the Treaty of Vienna of 1738, which formally ended the war, Leszczyński renounced his claim to the Polish throne[12] and was made Duke of Lorraine in compensation.
