The marathon Great Northern War was not the last war during Peter's tsardom, which saw one last short war in the south. In 1722, Peter allied with Georgia and Armenia, looking to seize land at the expense of the declining Safavid Persia and deny it to the Ottomans. Upon declaring war, Peter ordered the construction of the Caspian Flotilla and sailed down the Volga to command a joint land-sea campaign that took the city of Derbent, before being forced to return to Astrakhan for supplies. The Russian forces fought on, facing little resistance, without Peter's involvement, taking Resht late that year and Baku the next before Persia finally sued for peace.
