Alexander Sergeevich Griboedov, the famous Russian diplomat, had a brilliant career. He graduated from university and there is an opinion that he didn't get his PhD because of the war with Napoleon in 1812. Like majority of young Russian aristocrats, Griboedov joined the army to defend his motherland from the enemy.

After the war in 1816 Griboedov moved to the capital of Russia, St. Petersburg. There he worked in the Ministry of Foreign Affairs. He was making an outstanding career in the Ministry when once he fought in a duel and was ordered to leave St. Petersburg.

Griboedov was offered a job as a diplomat in Persia (now Iran) or the USA He chose Persia and spent there three years. After that he worked under General Yermolov in Georgia.

In January 1826 Griboedov was arrested on suspicion of his belonging to Decembrists but after a few months he was set free and went again to the caucasus.

In 1828 Griboedov was sent to St. Petersburg with the text of the Russian-Persian peace treaty. That year he got married and went to the capital of Persia - Tehran. He was a truly successful diplomat and stood for peace between the two countries. His contemporaries wrote that he was more important than the whole army.

But on 30 January 1829 nationalistic groups of radical Muslims attacked the Russian Embassy in Tehran. The building was ruined and all the people were killed.

Griboedov was buried in his favourite Tiflis in St. David's Monastery.
