Alexander Sergeyevich Griboyedov, formerly romanized as Alexander Sergueevich Griboyedoff, was a Russian diplomat, playwright, poet, and composer. His one notable work was the 1823 verse comedy Woe from Wit. He was Russia's ambassador to Qajar Persia, where he and all the embassy staff were massacred by an angry mob as a result of the rampant anti-Russian sentiment that existed through Russia's imposing of the Treaty of Gulistan (1813) and Treaty of Turkmenchay (1828), which had forcefully ratified for Persia's ceding of its northern territories comprising Transcaucasia and parts of the North Caucasus. Griboyedov played a pivotal role in the ratification of the latter treaty.
