Putin quickly reasserted control over Russia’s 89 regions and republics, dividing them into seven new federal districts, each headed by a representative appointed by the president. He also removed the right of regional governors to sit in the Federation Council, the upper house of the Russian parliament. Putin moved to reduce the power of Russia’s unpopular financiers and media tycoons—the so-called “oligarchs”—by closing several media outlets and launching criminal proceedings against numerous leading figures. He faced a difficult situation in Chechnya, particularly from rebels who staged terrorist attacks in Moscow and guerilla attacks on Russian troops from the region’s mountains; in 2002 Putin declared the military campaign over, but casualties remained high.
