The Rastafari movement, or Rasta, is a spiritual movement. It arose in the 1930s in Jamaica, a country with a predominantly Christian culture where 98% of the people were the black descendants of slaves. Most of its adherents worship Haile Selassie I, Emperor of Ethiopia (ruled 1930–1974), as God incarnate, the Second Advent, or the reincarnation of Jesus. Members of the Rastafari movement are known as Rastas, or Rastafari. The movement is sometimes referred to as "Rastafarianism", but this term is considered derogatory and offensive by some Rastas, who, being highly critical of "isms" (which they see as a typical part of "Babylon culture"), dislike being labelled as an "ism" themselves.

The name Rastafari is taken from Ras Tafari, the pre-regnal title of Haile Selassie I, composed of Amharic Ras (literally "Head", an Ethiopian title equivalent to Duke), and Haile Selassie's pre-regnal given name, Tafari. Rastafari are generally distinguished for asserting the doctrine that Haile Selassie I, the former and final Emperor of Ethiopia, is another incarnation of the Christian God, called Jah. Most see Haile Selassie I as Jah or Jah Rastafari, who is the second coming of Jesus Christ onto the Earth, but to others he is simply God's chosen king on earth.

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.
