Stroganov Letopis

The Stroganov Chronicle, also known under the name "On Capturing of the Siberian Land" (Строгановская летопись, "О взятии Сибирской земли" in Russian) is one of the earliest Siberian Chronicles.

There is no unanimous opinion in the Russian scientific community with regards to the exact date of this chronicle's compilation. It is generally considered that it was written either in 1620–1630 or 1668–1673. Some historians believe that parts of the Stroganov Chronicle are based on the Yesipov Chronicle, which was written in 1636. The Stroganov Chronicle is based on annalistic data (which didn't survive to this day) and materials of the Stroganovs' archives, including their correspondence with Yermak's druzhina. The Stroganov Chronicle tells in great detail about the events of the early stage of the annexation of Siberia in favor of Russia. The Stroganovs' initiative to organize Yermak's campaign is put in the forefront in this chronicle.
