Joseph Stalin seemed at first unlikely to win power after Lenin's death in 1924. But he had secured a powerful position in the Party, and was able to discredit his rivals one by one. By 1929 Stalin reigned supreme, and, once he was in power, he was now ready to make radical changes in economic policy.
