IN: The Oromo people (Oromo: Oromoo; Ge'ez: 'oromo; 'Oromo) are an ethnic group inhabiting Ethiopia and parts of Kenya and Somalia. They are the largest ethnic group in Ethiopia and the wider Horn of Africa. According to the 2007 census, they represent approximately 34.5% of Ethiopia's population, while others estimate they make up about 40% of the population. With the total Ethiopian population thought to be over 102 million, the number of Oromo people exceeds 35 million in Ethiopia alone.

In the late 16th and early 17th centuries, conquests by the Abyssinian Empire in southern and southwestern Ethiopia had left a territorial vacuum, allowing the pastoral Oromo to settle in the vacated territories and incorporate socially dislocated peoples into their gada system. As they moved into earlier Islamic hubs, the Oromos increasingly adopted Islam, and in the process markedly grew their Muslim adherent base to become one of the larger such populations in the Horn region. Pastoralist Oromos also took slaves from their own community's urban areas, as well as from other communities. According to the historian Paul E. Lovejoy, slavery was at this time an important aspect of the social, political and economic structure of parts of Ethiopia. The slaves were classified into two groups: "red" slaves who spoke Afroasiatic languages, and "black" ("Negroid") slaves called Shanqalla who spoke Nilo-Saharan languages. The "red" slaves were primarily courtesans and were more expensive; they were given light duties so as to preserve their looks. The "black" slaves were much less expensive, and toiled in the fields and in Christian Abyssinian households. The "red" slaves, among which were Galla individuals, formed the bulk of captives who were exported from Abyssinian territory to the Arabian peninsula and Persian Gulf regions, to Ottoman Empire markets, to Egypt and elsewhere. Young female Oromo slaves served as concubines and household workers, while males were in demand for private armies and servile labor. Oromos too enslaved other ethnic groups. According to a report by Bermudes, in the 16th century, Oromos during their wars were fierce and cruel, mutilating and enslaving the people in the regions they conquered. Emperor Galawdewos battled with Oromos without much success and sought Portuguese help. In the era of Imam Ahmad, according to Bahrey's records, Oromo Luba 'tribes' made war in Dawaro against Adal Mabraq, devastating the region and occupying it. They also took over Fatagar and Faj, forcing its previous inhabitants into slavery. The pagan Galla and animist Sidama or Agew slaves made up the slave caravans coming out of Ethiopia, as slavers avoided Christian or Muslim slaves. The central Amhara provinces were a part of major Afar slave caravan trade routes from the southern and southwestern Galla, Sidama and Gurage regions to the northern and eastern Ethiopia. Thousands of slaves were exported every year by Jabarti, Jalaba, Afar, Somali and Arab merchants as the income from this trade was lucrative. According to Ira M. Lapidus, a professor of Middle Eastern and Islamic History, the Ethiopian slave trade benefited the Muslims, and increased the Islamization of the Oromo people.

IN: Edgar Yipsel "Yip" Harburg (born Isidore Hochberg, Yiddish: ysydvr hvkbrg; April 8, 1896 - March 5, 1981) was an American popular song lyricist who worked with many well-known composers. He wrote the lyrics to the standards "Brother, Can You Spare a Dime?"

Harburg, the youngest of four surviving children (out of ten), was born Isidore Hochberg on the Lower East Side of New York City on April 8, 1896. His parents, Lewis Hochberg and Mary Ricing, were Yiddish-speaking Orthodox Jews who had emigrated from Russia. He later adopted the name Edgar Harburg, and came to be best known as Edgar "Yip" Harburg. He attended Townsend Harris High School, where he and Ira Gershwin, who met over a shared fondness for Gilbert and Sullivan, worked on the school paper and became lifelong friends. According to his son Ernie Harburg, Gilbert and Irish dramatist George Bernard Shaw taught his father, a "democratic socialist, [and] sworn challenger of all tyranny against the people, that 'humor is an act of courage' and dissent". After World War I, Harburg returned to New York and graduated from City College (later part of the City University of New York), which Ira Gershwin had initially attended with him, in 1921. After Harburg married and had two children, he started writing light verse for local newspapers. He became a co-owner of Consolidated Electrical Appliance Company, but the company went bankrupt following the crash of 1929, leaving Harburg "anywhere from $50,000 - $70,000 in debt," which he insisted on paying back over the course of the next few decades. At this point, Harburg and Ira Gershwin agreed that Harburg should start writing song lyrics. Gershwin introduced Harburg to Jay Gorney, who collaborated with him on songs for an Earl Carroll Broadway review (Earl Carroll's Sketchbook): the show was successful and Harburg was engaged as lyricist for a series of successful revues, including Americana in 1932, for which he wrote the lyrics of "Brother, Can You Spare a Dime?" to the tune of a lullaby Gorney had learned as a child in Russia. This song swept the nation, becoming an anthem of the Great Depression. Harburg was a staunch critic of religion and an atheist. He wrote a poem entitled "Atheist" that summarized his views on god and religion.
