Freestyle rap (also known as battle rap, battle rapping or battle rhyming) commonly refers to rap lyrics which are improvised through an a cappella or with instrumental beats, i.e. performed with no previously composed lyrics, or "off the top of the head". It is similar to other improvisational music such as jazz - Myka 9 of Freestyle Fellowship describes it as being "like a jazz solo" where there is a lead saxophonist acting as the improviser and the rest of the band providing the beat. Rap battles are sometimes improvised in this way. It is similar in both form and function to the ancient practice of flyting.

Originally, in Old school hip hop of the 1980s, the term ‘freestyle’ referred to a pre-written rap verse that was not on any particular subject matter, but rather was written for the purpose of demonstrating skill. The term is still occasionally used in this way, though since the 1990s, the majority of today’s artists use it to mean improvised rapping.

Battling is generally believed to have originated in the East Coast hip hop scene in the late 1970s.^{[citation needed]} One of the earliest and most famous battles was in December 1981 (evidenced by BB's DJ asking if the crowd is ready for '82) when Kool Moe Dee challenged Busy Bee Starski - Busy Bee Starski's defeat by the more complex raps of Kool Moe Dee meant that "no longer was an MC just a crowd-pleasing comedian with a slick tongue; he was a commentator and a storyteller", which KRS-One also credits as creating a shift in rapping in the documentary Beef.

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.

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.

In 1984, he co-founded the spin-off Bain Capital, a private equity investment firm that became highly profitable and one of the largest such firms in the nation. His net worth is estimated at $190–250 million, wealth that has helped fund his political campaigns.
