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 is the Convention People's Party?

there was considerable pressure on Nkrumah from his supporters to leave the UGCC and form his own party.

The Vedic period or Vedic age (c. 1500 - c. 600 BCE) is the period in the history of the Indian subcontinent intervening between the end of the urban Indus Valley Civilization, and a second urbanisation which began in c. 600 BCE. It gets its name from the Vedas, which are liturgical texts containing details of life during this period that have been interpreted to be historical and constitute the primary sources for understanding the period. The Vedas were composed and orally transmitted by speakers of an Old Indo-Aryan language who had migrated into the northwestern regions of the Indian subcontinent early in this period. The associated Vedic culture was tribal and pastoral until c. 1200 or 1100 BCE, and centred in the Punjab.
The commonly accepted period of earlier Vedic age is dated back to the second millennium BCE. After the collapse of the Indus Valley Civilisation, which ended c. 1900 BCE, groups of Indo-Aryan peoples migrated into north-western India and started to inhabit the northern Indus Valley. The Indo-Aryans were a branch of the Indo-Iranians, which--according to the most widespread hypothesis--have originated in the Andronovo culture in the Bactria-Margiana era, in present northern Afghanistan. Some writers and archaeologists have opposed the notion of a migration of Indo-Aryans into India. Edwin Bryant and Laurie Patton used the term "Indo-Aryan Controversy" for an oversight of the Indo-Aryan Migration theory, and some of its opponents. These ideas are outside the academic mainstream. Mallory and Adams note that two types of models "enjoy significant international currency" as to the Indo-European homeland, namely the Anatolian hypothesis, and a migration out of the Eurasian steppes. According to Upinder Singh, "The original homeland of the Indo-Europeans and Indo-Aryans is the subject of continuing debate among philologists, linguists, historians, archaeologists and others. The dominant view is that the Indo-Aryans came to the subcontinent as immigrants. Another view, advocated mainly by some Indian scholars, is that they were indigenous to the subcontinent." The knowledge about the Aryans comes mostly from the Rigveda-samhita, i. e. the oldest layer of the Vedas, which was composed c. 1500-1200 BCE. They brought with them their distinctive religious traditions and practices. The Vedic beliefs and practices of the pre-classical era were closely related to the hypothesised Proto-Indo-European religion, and the Indo-Iranian religion. According to Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River (present-day Uzbekistan) and (present-day) Iran. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria-Margiana Culture.

What were differences after inhabiting the northern Indus Valley?
"a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria-Margiana Culture.
