The military setbacks of Rusas I ended Urartu’s political power. But his son Argishti II (c. 712–685) and successors continued the royal tradition of developing the country’s natural resources, and Urartian culture not only survived but continued to flourish for a while, despite its political impotence. The Urartians were finally overcome by invading Armenians toward the end of the 7th century bc.
