Some context: Kwame Nkrumah PC (21 September 1909 - 27 April 1972) was a Ghanaian politician and revolutionary. He was the first prime minister and president of Ghana, having led it to independence from Britain in 1957. An influential advocate of Pan-Africanism, Nkrumah was a founding member of the Organization of African Unity and winner of the Lenin Peace Prize in 1962. After twelve years abroad pursuing higher education, developing his political philosophy, and organizing with other diasporic pan-Africanists, Nkrumah returned to Gold Coast to begin his political career as an advocate of national independence.
Beginning in April 1949, there was considerable pressure on Nkrumah from his supporters to leave the UGCC and form his own party. On 12 June 1949, he announced the formation of the Convention People's Party (CPP), with the word "convention" chosen, according to Nkrumah, "to carry the masses with us." There were attempts to heal the breach with the UGCC; at one July meeting, it was agreed to reinstate Nkrumah as secretary and disband the CPP. But Nkrumah's supporters would not have it, and persuaded him to refuse the offer and remain at their head.  The CPP adopted the red cockerel as its symbol - a familiar icon for local ethnic groups, and a symbol of leadership, alertness, and masculinity. Party symbols and colours (red, white, and green) appeared on clothing, flags, vehicles, and houses. CPP operatives drove red-white-and-green vans across the country, playing music and rallying public support for the party and especially for Nkrumah. These efforts were wildly successful, especially because previous political efforts in the Gold Coast had focused exclusively on the urban intelligentsia.  The British convened a selected commission of middle-class Africans, including all of the Big Six except Nkrumah, to draft a new constitution that would give Ghana more self-government. Nkrumah saw, even before the commission reported, that its recommendations would fall short of full dominion status, and began to organise a Positive Action campaign. Nkrumah demanded a constituent assembly to write a constitution. When the governor, Charles Arden-Clarke, would not commit to this, Nkrumah called for Positive Action, with the unions beginning a general strike to begin on 8 January 1950. The strike quickly led to violence, and Nkrumah and other CPP leaders were arrested on 22 January, and the Evening News was banned. Nkrumah was sentenced to a total of three years in prison, and he was incarcerated with common criminals in Accra's Fort James.  Nkrumah's assistant, Komla Agbeli Gbedemah, ran the CPP in his absence; the imprisoned leader was able to influence events through smuggled notes written on toilet paper. The British prepared for an election for the Gold Coast under their new constitution, and Nkrumah insisted that the CPP contest all seats. The situation had become calmer once Nkrumah was arrested, and the CPP and the British worked together to prepare electoral rolls. Nkrumah stood, from prison, for a directly-elected Accra seat. Gbedemah worked to set up a nationwide campaign organisation, using vans with loudspeakers to blare the party's message. The UGCC failed to set up a nationwide structure, and proved unable to take advantage of the fact that many of its opponents were in prison.  In the February 1951 legislative election, the first general election to be held under universal franchise in colonial Africa, the CPP was elected in a landslide. The CPP secured 34 of the 38 seats contested on a party basis, with Nkrumah elected for his Accra constituency. The UGCC won three seats, and one was taken by an independent. Arden-Clarke saw that the only alternative to Nkrumah's freedom was the end of the constitutional experiment. Nkrumah was released from prison on 12 February, receiving a rapturous reception from his followers. The following day, Arden-Clarke sent for him and asked him to form a government.
what was it that he was leaving
A: UGCC and form his own party.
Some context: Pantera was an American heavy metal band from Arlington, Texas. The group was formed in 1981 by the Abbott brothers - drummer Vinnie Paul and guitarist Dimebag Darrell - along with lead vocalist Terry Glaze. Bassist Rex Brown joined the band the following year, replacing Tommy D. Bradford, who was the unofficial original.
Shortly after Power Metal was released, "Diamond Darrell", as he was then known, auditioned for Megadeth's vacant guitarist slot, and was invited to join the band. Darrell insisted his brother, bandmate Vinnie Paul, be included, but because Chuck Behler was still in the band at the time, Darrell declined and Dave Mustaine instead decided on Marty Friedman. The Abbott brothers refocused their attention on Pantera, and in 1989 they were given their first shot at commercial success. 1989 was also when the band formed their relationship with Walter O'Brien at Concrete Management (the management arm of Concrete Marketing), who remained their manager until they disbanded in 2003.  After being turned down "28 times by every major label on the face of the Earth", Atco Records representatives Mark Ross and Stevenson Eugenio were asked by their boss Derek Shulman, who was interested in signing Pantera, to see the band perform after Hurricane Hugo stranded them in Texas. Ross was so impressed by the band's performance that he called his boss that night, suggesting that Pantera be signed to the label. Atco Records accepted, and at the close of 1989, the band recorded its major label debut at Pantego Studios.  Released on July 24, 1990, and produced by Terry Date and Pantera, Cowboys from Hell was another leap into heavier territory. Pantera showed a more extreme style on this outing, leaving behind its glam metal influences in favor of mid-tempo thrash metal dubbed "power groove" (groove metal) by the band. Although Anselmo still used Rob Halford-influenced vocals, he also adopted a more abrasive delivery. Darrell's more complex guitar solos and riffs, along with his brother's faster-paced drumwork were evidence of the band's extreme transformation. The album marked a critical juncture in the band's history. Many fans, as well as the band itself, consider it Pantera's "official" debut. Cowboys included the tracks "Cemetery Gates", a brooding seven-minute piece that focuses on death and religion, and the thrashing title track, which gave the band members their nickname and asserted their raucous personality and style.  So began the Cowboys from Hell tour alongside thrash acts Exodus and Suicidal Tendencies. In 1991, Rob Halford performed with the band onstage, which led Pantera (along with Annihilator) to open for Judas Priest on its first show in Europe. They also opened for bands like Fates Warning, Prong, Mind over Four and Morbid Angel, and co-headlined a North American tour with Wrathchild America. The band eventually landed a billing for "Monsters in Moscow" with AC/DC and Metallica in September 1991, where they played to a crowd of over 500,000 in celebration of the new freedom of performing Western music in the Soviet Union shortly before its collapse three months later. The band was often found at the Dallas club "the Basement", where the band shot the videos for "Cowboys from Hell" and "Psycho Holiday". Pantera's 2006 home video compilation 3 Vulgar Videos from Hell features performances of "Primal Concrete Sledge", "Cowboys from Hell", "Domination", and "Psycho Holiday" from the show in Moscow.
