After years of stagnation, the "new thinking" of younger Communist apparatchik began to emerge. Following the death of terminally ill Konstantin Chernenko, the Politburo elected Mikhail Gorbachev to the position of General Secretary of the Communist Party of the Soviet Union (CPSU) in March 1985. At 54, Gorbachev was the youngest person since Joseph Stalin to become General Secretary and the country's first head of state born a Soviet citizen instead of a subject of the tsar. During his official confirmation on 11 March, Foreign Minister Andrei Gromyko spoke of how the new Soviet leader had filled in for Chernenko as CC Secretariat, and praised his intelligence and flexible, pragmatic ideas instead of rigid adherence to party ideology. Gorbachev was aided by a lack of serious competition in the Politburo. He immediately began appointing younger men of his generation to important party posts, including Nikolai Ryzhkov, Secretary of Economics, Viktor Cherbrikov, KGB Chief, Foreign Minister Eduard Shevardnadze (replacing the 75-year-old Gromyko), Secretary of Defense Industries , and Secretary of Construction Boris Yeltsin. Removed from the Politburo and Secretariat was Grigory Romanov, who had been Gorbachev's most significant rival for the position of General Secretary. Gromyko's removal as Foreign Minister was the most unexpected change given his decades of unflinching, faithful service compared to the unknown, inexperienced Shevardnadze.
