Russo-Prussian alliance

[1] Signed on 11 April 1764, it laid the foundation for the "northern system" in Russian politics in which Russia and Prussia were allied with Great Britain.

[2] According to some historians, Russia would become the dominating partner in the alliance, partially fulfilling one of its goals from the Seven Years' War: increased influence over Prussia.

[6] Not insignificantly, the treaty also allowed Prussia and Russia to exercise better control over the Polish–Lithuanian Commonwealth; both parties agreed to prevent the election of a third king from the House of Wettin.

[7] Advocated by Grigory Potemkin, this new direction reduced the strategic value of Prussia as an ally to Russia, and made Austria once again a more appealing candidate.

[7] The Russo-Prussian alliance was again extended in 1777, but at the imperial court in Saint Petersburg the influence of Panin's pro-Prussian faction was eclipsed by Potemkin's pro-Austrian one.
