Editing False Dmitry III (section)

==Biography==
Supposed to have been a [[deacon]] called Sidorka, he appeared suddenly, from behind the river [[Narva River|Narva]], in the [[Ingria]]n town of [[Ivangorod]], proclaiming himself the Tsarevich Dmitry Ivanovich, on March 28, 1611. The [[Cossacks]], ravaging the environs of [[Moscow]], acknowledged him as [[Tsar]] on March 2, 1612, and under threat of vengeance in case of non-compliance, the gentry of [[Pskov]] also "kissed the cross" (i.e., swore allegiance) to the ''rebel/criminal of Pskov'' (псковский вор), as he was usually nicknamed. On May 18, 1612, he fled from Pskov, was seized and delivered up to the authorities at Moscow, and was secretly executed there.{{sfn|Bain|1911|p=984}}
