Petro Oleksiiovych Poroshenko (born 26 September 1965) is a Ukrainian politician and oligarch who served as the fifth president of Ukraine from 2014 to 2019. He served as the Minister of Foreign Affairs from 2009 to 2010, and as the Minister of Trade and Economic Development in 2012. From 2007 until 2012, he headed the Council of Ukraine's National Bank. He was elected president in 2014.
During his presidency, Poroshenko led the country through the first phase of the war in Donbas, pushing the Russian separatist forces into the Donbas Region. He began the process of integration with the European Union by signing the European Union–Ukraine Association Agreement. Poroshenko's domestic policy promoted the Ukrainian language, nationalism, inclusive capitalism, decommunization, and administrative decentralization. In 2018, Poroshenko helped create the autocephalous Orthodox Church of Ukraine, separating Ukrainian churches from the Moscow Patriarchate. His presidency was distilled into a three-word slogan, employed by both supporters and opponents: armiia, mova, vira (English: military, language, faith). As a candidate for a second term in 2019, Poroshenko was defeated by Volodymyr Zelenskyy.
