Stanislaw's son-in-law Louis XV supported his claims to the Polish throne after the death of August II the Strong in 1733, which led to the War of the Polish Succession. On 11 September 1733, Stanisław himself arrived at Warsaw, having traveled night and day through central Europe disguised as a coachman. On the following day, despite many protests, Stanisław was duly elected King of Poland for the second time. However, Russia was opposed to any nominee of France and Sweden. Russia protested against his election at once, in favor of the new Elector of Saxony, as being the candidate of her Austrian ally.
