Ghanas first president, Kwame Nkrumah, was an early promoter of Pan-Africanism. While it wouldnt catch on in his lifetime, eventually his vision became true with the foundation of the African Union.
Ghana has suffered from the requisite Cold War-era military dictatorships, but during Jerry Rawlings' second period in office (1981-2000) it lurched steadily towards democracy, and Rawlings even won elections in 1992 and 1996 that the international community judged largely free and fair, even if the domestic opposition disagreed. It's since transitioned to being a stable democracy.
Though its a mildly poor country, Ghana has been growing steadfastly in the later years, especially the tourism branch, which attracts all kinds of rich Americans, Europeans and others. It also has a bit of a computer industry developing, thanks to a bunch of charities sending computers to the country. Usually they were sent there to be disposed of, but a few Ghanians have actually have salvaged usable parts from them and apparently reverse-engineered a few.
The religion is mainly Christian, with a Islamic minority concentrated on the north. There are also the traditional religions of the zone.
By the way, the name Ghana comes from the ancient Empire of Ghana, one of the first West African empires. However, the empires frontiers never reached Ghanas actual frontiers.
