In 1717, Russia cemented its position as the dominant force in Poland, in the aftermath of the Great Northern War and amid the growing likelihood of a civil war in Poland between the Polish king August II the Strong and the Polish nobility. Russian tsar Peter I the Great, posing as the conciliator between the Commonwealth king and the szlachta, ordered units of the Russian army to enter Polish territory—using the treaties of alliance from the Great Northern War—and coerced the Polish Sejm of 1717 into accepting his 'compromise'. During that Sejm (known as the Silent Sejm, as only one person was allowed to speak aloud), laws were passed that not only eliminated the possibility of August strengthening his power, but also ensured by means of restricted taxation (and thus a constrained Polish army) that Poland would not be able to interfere with similar Russian interventions in the future. In reality, if not the letter of the law, the reforms of the Silent Sejm meant that the Commonwealth became a Russian protectorate, and it would be Russian ambassadors and envoys who would be responsible for this territory under the tsar. In 1730 than Russian ambassador to Poland, Karl Gustav von Löwenwolde, was instrumental in the Alliance of the Three Black Eagles (or Löwenwolde's Treaty), an agreement between Commonwealth's neighbours to preserve the dysfunctional state of affairs within it. Russian influence on Poland further increased during the War of the Polish Succession (1733–1738), when Russian military intervention overturned the result of the royal election of Stanisław Leszczyński.
