This footage is part of a documentary film about the Russian Empire. In this episode, you can see a Qajar delegation sent to St. Petersburg to convey the Shah of Persia’s regret about the murder of the Russian ambassador, Aleksander Griboyedov, and his staff in Tehran. Apparently, when Griboyedov had arrived to the capital, he started to locate Georgian women who were married to Persian nobles in order to return them to Russia. This caused an anger in Tehran, and people stormed the Russian embassy killing the new ambassador.
