The President of Germany is the head of state of Germany. The current official title is President of the Federal Republic of Germany. The official German name is Bundespräsident (der Bundesrepublik Deutschland). Germany has a parliamentary system of government and so the position of President is largely ceremonial. Nevertheless the president has some important "reserve powers" in case of political instability (such as those provided for by Article 81 of the Basic Law).

The president is elected by the Federal Convention, a body established solely for that purpose. The first official residence of the president is the Bellevue Palace in Berlin. The president's second official residence is the Hammerschmidt Villa in Bonn.

The office of President of Germany was first created in 1919, replacing the emperor as head of state, with Friedrich Ebert (SPD) serving as the first president. The presidential standard, adopted in 1921, is still used today. While Germany had a semi-presidential system during the Weimar Republic, today's presidential office is largely ceremonial, with the Chancellor of Germany generally seen as wielding the effective power.

Germany (ⁱ/ˈdʒɜrməni/), officially the Federal Republic of Germany (German: Bundesrepublik Deutschland, pronounced [ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant] ( listen)), is a federal parliamentary republic in Europe. The country consists of 16 states while the capital and largest city is Berlin. Germany covers an area of 357,021 km² and has a largely temperate seasonal climate. With 81.8 million inhabitants, it is the most populous member state and the largest economy in the European Union. It is one of the major political powers of the European continent and a technological leader in many fields.

A region named Germania, inhabited by several Germanic peoples, was documented before AD 100. During the Migration Period, the Germanic tribes expanded southward, and established successor kingdoms throughout much of Europe. Beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation while southern and western parts remained dominated by Roman Catholic denominations, with the two factions clashing in the Thirty Years' War, marking the beginning of the Catholic–Protestant divide that has characterized German society ever since. Occupied during the Napoleonic Wars, the rise of Pan-Germanism inside the German Confederation resulted in the unification of most of the German states into the German Empire in 1871 which was Prussian dominated. After the German Revolution of 1918–1919 and the subsequent military surrender in World War I, the Empire was replaced by the Weimar Republic in 1918, and partitioned in the Treaty of Versailles. Amidst the Great Depression, the Third Reich was proclaimed in 1933. The latter period was marked by Fascism and World War II. After 1945, Germany was divided by allied occupation, and evolved into two states, East Germany and West Germany. In 1990 Germany was reunified.

Vladimir Vladimirovich Putin (Russian: Влади́мир Влади́мирович Пу́тин; IPA: [vɫɐˈdʲimʲɪr vɫɐˈdʲimʲɪrəvʲɪtɕ ˈputʲɪn] ( listen); born 7 October 1952) is a Russian politician who has been the President of Russia since 7 May 2012. Putin previously served as President from 2000 to 2008 and as Prime Minister of Russia from 1999 to 2000, and again from 2008 to 2012. Putin also serves as chairman of United Russia and Chairman of the Council of Ministers of the Union of Russia and Belarus. He became acting President on 31 December 1999, when president Boris Yeltsin resigned in a surprising move. Putin won the 2000 presidential election; in 2004 he was re-elected for a second term lasting until 7 May 2008.

Because of constitutionally mandated term limits, Putin was ineligible to run for a third consecutive presidential term. After his successor Dmitry Medvedev won the 2008 presidential election, Putin was nominated by Medvedev to be Russia's Prime Minister; Putin took office on 8 May 2008 and a period of so-called "tandemocracy" followed. In September 2011, Putin and Medvedev agreed he should seek a third, non-consecutive term in the 2012 presidential election, which he won in the first round on 4 March 2012.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.

Joachim Gauck pronounced [joːˈʔaxiːm ɡaʊ̯k] (born 24 January 1940 in Rostock) is the current President of Germany (since 18 March 2012). A former Lutheran pastor, he came to prominence as an anti-communist civil rights activist in East Germany.

During the Peaceful Revolution, he was a co-founder of the New Forum opposition movement in East Germany, which contributed to the downfall of the Soviet-backed dictatorship of the Socialist Unity Party of Germany (SED). In 1990 he served as a member of the only freely elected People's Chamber for the Alliance 90. Following German reunification, he was elected by the Bundestag as the first Federal Commissioner for the Stasi Archives, serving from 1990 to 2000. As Federal Commissioner, he earned recognition as a "Stasi hunter" and "tireless pro-democracy advocate," exposing the crimes of the former communist secret police.

He was nominated as the candidate of the SPD and the Greens for President of Germany in the 2010 election, but narrowly lost to Christian Wulff, the candidate of the government coalition. His candidacy was met by significant approval of the population and the media; Der Spiegel described him as "the better President" and the Bild called him "the president of hearts." After Christian Wulff had stepped down, Gauck was elected President with 991 of 1228 votes in the Federal Convention in the 2012 election, as a nonpartisan consensus candidate of the CDU, the CSU, the FDP, the SPD and the Greens.
