Russo-Swedish War (1788–1790) in the context of "Russo-Turkish War (1787–1792)"

Samuel Greig, also known as Samuil Karlovich Greig, (Russian: Самуил Карлович Грейг; 30 November 1735 – 26 October 1788) was a British-born Russian naval officer who served in the Seven Years' War, Russo-Turkish War and Russo-Swedish War. His son Aleksey Greig also served in the Imperial Russian Navy.

Prince Michael Andreas Barclay de Tolly (baptised 27 December [O.S. 16 December] 1761 – 26 May [O.S. 14 May] 1818) was a Russian field marshal who figured prominently in the Napoleonic Wars.

Barclay was born into a Baltic German family from Livland. His father was the first of his family to be accepted into the Russian nobility. In Russian service he was known as Mikhail Bogdanovich. Barclay joined the Imperial Russian Army at a young age in 1776. He served with distinction in the Russo-Turkish War (1787–92), the Russo-Swedish War (1788–1790), and the Kościuszko Uprising (1794).

The Treaty of Värälä (sometimes known as the Treaty of Wereloe) was signed in Värälä, Elimäki Municipality, Finland, between Russia (represented by Otto Heinrich Igelström) and Sweden (represented by Gustaf Mauritz Armfelt). It was signed on 14 August 1790 and concluded the Russo-Swedish War. The treaty confirmed status quo ante bellum with respect to the borders; however, Russia's right to interfere with Swedish interior affairs from the Treaty of Nystad was expressly revoked. The provisions of the previous Treaty of Åbo were basically confirmed.

A year later, on 19 October 1791, a convention was signed in Stockholm, whereby the countries pledged to assist each other in case of foreign attack. The treaty anticipated the First Coalition in its being directed against Revolutionary France. Catherine bound herself to pay her new ally annual subsidies amounting to 300,000 rubles. Gustav III had sent to his cousin, Catherine II of Russia, a letter in which he besought her to "forget the war as a passing cloud" and invoked their common blood as his claim to enjoy amitie with his cousin.
