Pammakaristos Church, also known as the Church of Theotokos Pammakaristos (Greek: Θεοτόκος ἡ Παμμακάριστος, "All-Blessed Mother of God"), in 1591 converted into a mosque and known as Fethiye Mosque (Turkish: Fethiye Camii, "mosque of the conquest") and today partly a museum, is one of the most famous Byzantine churches in Istanbul, Turkey. The parekklesion, besides being one of the most important examples of Constantinople's Palaiologan architecture, has the largest amount of Byzantine mosaics in Istanbul after the Hagia Sophia and Chora Church.

The building is located in the Çarşamba neighbourhood within the district of Fatih inside the walled city of Istanbul. Theotokos Pammakaristos overlooks the Golden Horn.

According to most scholars, the church was built between the eleventh and the twelfth centuries. Many historians and archaeologists believe that the original structure of the church can be attributed to Michael VII Ducas (1071–1078), others put its foundation in the Comnenian period. It has also been suggested by the Swiss scholar and Byzantinist Ernest Mamboury that the original building was erected in the 8th century.

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.
