Medvedev was elected President in the 2008 election. He was regarded as more liberal than his predecessor, Vladimir Putin, who was also appointed Prime Minister during Medvedev's presidency. Medvedev's top agenda as president was a wide-ranging modernisation programme, aiming at modernising Russia's economy and society, and lessening the country's reliance on oil and gas. During Medvedev's tenure, the New START nuclear arms reduction treaty was signed by Russia and the United States, Russia emerged victorious in the Russo-Georgian War, and recovered from the Great Recession. Medvedev also launched an anti-corruption campaign, despite having been accused of corruption himself.
