Vladimir Putin, Russian colonel and politician, 4th President of Russia
Vladimir Vladimirovich Putin (; Russian: Владимир Владимирович Путин; [vlɐˈdʲimʲɪr vlɐˈdʲimʲɪrəvʲɪtɕ ˈputʲɪn] (listen); born 7 October 1952) is a Russian politician and former intelligence officer who is the president of Russia, a position he has filled since 2012, and previously from 2000 until 2008. He was also the prime minister from 1999 to 2000, and again from 2008 to 2012. Putin is the second-longest currently-serving European president after Alexander Lukashenko of Belarus.

He worked as a KGB foreign intelligence officer for 16 years, rising to the rank of lieutenant colonel, before resigning in 1991 to begin a political career in Saint Petersburg. He moved to Moscow in 1996 to join the administration of president Boris Yeltsin. He briefly served as director of the Federal Security Service (FSB) and secretary of the Security Council, before being appointed as prime minister in August 1999. After the resignation of Yeltsin, Putin became acting president, and less than four months later was elected outright to his first term as president. He was reelected in 2004. As he was then constitutionally limited to two consecutive terms as president, Putin served as prime minister again from 2008 to 2012 under Dmitry Medvedev, and returned to the presidency in 2012 in an election marred by allegations of fraud and protests; he was reelected again in 2018. In April 2021, following a referendum, he signed into law constitutional amendments including one that would allow him to run for reelection twice more, potentially extending his presidency to 2036.During Putin's first tenure as president, the Russian economy grew on average by seven percent per year, following economic reforms and a fivefold increase in the price of oil and gas. Putin led Russia during the Second Chechen War, restoring federal control of Chechnya. As prime minister under Medvedev, he oversaw military reform and police reform, as well as Russia's victory in its war against Georgia. During his third term as president, Russia annexed Crimea and sponsored a war in eastern Ukraine with several military incursions made, resulting in international sanctions and a financial crisis in Russia. During his fourth term as president, his government responded to the COVID-19 pandemic, and he presided over a military buildup on the border of Ukraine. In February 2022, Putin ordered a full-scale invasion of Ukraine, leading to international condemnation and isolation, as well as expanded sanctions, causing a financial crisis in Russia, and calls for the prosecution of Putin for war crimes.Under Putin's leadership, Russia has experienced democratic backsliding and a shift to authoritarianism. Putin's rule has been characterised by endemic corruption, the jailing and repression of political opponents, the intimidation and suppression of independent media in Russia, and a lack of free and fair elections. Putin's Russia has scored poorly on Transparency International's Corruption Perceptions Index, the Economist Intelligence Unit's Democracy Index, and Freedom House's Freedom in the World index.
