The results of the Treaty of Georgievsk proved disappointing for the Georgians. King Erekle's adherence to it prompted Persia's new ruler, Agha Mohammad Khan, who had sent several ultimatums, to invade, as he sought to re-establish Persia's traditional suzerainty over the region. Russia did nothing to help the Georgians during the disastrous Battle of Krtsanisi in 1795, which left Tbilisi sacked and Georgia ravaged (including the west Georgian kingdom of Imereti, ruled by Erekle II's grandson, King Solomon II). Belatedly, Catherine declared war on Persia and sent an army to Transcaucasia. But her death shortly thereafter (November 1796) put an end to Russia's Persian Expedition of 1796, as her successor, Paul, turned to other strategic objectives. Persia's Shahanshah next contemplated the removal of the Christian population from eastern Georgia and eastern Armenia, launching the campaign from Karabagh. His goal was frustrated not by Russian resistance, but by a Persian assassin in 1797.
