The greatest American historian Nelson Dibvoise piece by piece, based on the evidence of ancient authors, archeological and numismatic data, recreated the history of one of the greatest empires of antiquity - the Parthian kingdom. At the best time of its existence, Parthia absorbed the territories of modern Iran, Iraq, Afghanistan, Pakistan and Turkmenistan and competed with another great empire - the Roman. In the spring of 53 BC. e. The Parthians inflicted a severe defeat on the Roman army of Marcus Licinius Crassus at the Battle of Carrhae and by 40 BC. e. captured almost all of Asia Minor, Syria and Palestine. The Romans' attempts to take revenge for a long time did not lead to anything, but they were helped by numerous pretenders to the Parthian throne, who in the internecine struggle brought their power to complete exhaustion. Having existed for almost five centuries, Parthia disintegrated. The Sassanid Empire arose from its ruins.
