It was during Lzedmitry (False Dmitry/Dimitry) I & II era, when a some obscure Polish nobleman (actually to successive claimed he was the miraculously surviving Tsarevich Dimitry, who was the heir of Russia (the real Dimityr was assasinated roughly twenty years earlier). He posed as a Russian, so many people accepted him at first. Once he became the Tsar, though, he began leaning towards Catholics and Poles, who helped him ascend to the throne and eventually invited them into Russia as the people grew restless. The Poles as well as some other Western countries began imposing their force on Russia. Soon a full-fledged rebellion broke out. There was a seven-year war and the Poles were defeated. The Poles therefore invaded Russia, but not actually controlled it or forced it to accept any king for any period of time. The rebellion broke out as soon as Lzedmitry was installed.
