African American Obadele Kambon has never looked back since moving to Ghana in 2008. He vowed to quit the US for West Africa after being the victim of what he believed was a racially motivated arrest. Mr Kambon has now built a successful life in the place that was once at the heart of the slave trade and enjoys the freedom which, he says, was denied to him in the US, his birthplace. He says he no longer looks over his shoulder, worrying that police will pull him over or, worse still, kill his son. This was the fate that befell 12-year-old Tamir Rice who, was shot dead in a park in Cleveland, Ohio, in 2014 while playing with a pellet gun that police said they thought was real.

Wrongly arrested

The young boy's death sparked protests in Cleveland, and became a focal point for the Black Lives Matter movement. Mr Kambon says the turning point in his life came in 2007. He was arrested and put on trial in Chicago - where he lived - after being accused by police officers of having a loaded firearm under his car seat and intending to commit a drive-by shooting. In fact, he had an unloaded licensed gun, used earlier to secure a campsite, in his car boot. Mr Kambon recalls that he was shocked by the charges and as he sat in the court, he vowed: "Never again will I allow myself to be in a jurisdiction where corrupt white police officers and a judge will take me away from my family, wife and kids just on a whim."

Mr Kambon - who was a young academic teaching at schools and universities in the Chicago area - was eventually cleared of the charge. He then saved up about $30,000 (£24,000) and relocated to Ghana's capital, Accra, the following year. He was joined by his wife Kala, and the couple now have three children - Ama, Kwaku and Akosua.

Immersed in African spirituality

Mr Kambon started his doctoral studies in linguistics at the University of Ghana in 2009 and now teaches at its Institute of African Studies. Since moving to Ghana, he has noticed that he no longer feels he is a victim of racial profiling or racial abuse. He points out that his friend felt likewise when he relocated, and quipped: "Wow, this is what it must feel like to be a white person in America, just to be able to live without worrying that something is going to happen to you." Mr Kambon concedes that not everything is "hunky dory" in Ghana.

He was also shocked to discover that in a complex where he lived with four other families children did not speak any African language. "There was a point where the children had an Ewe mother and if you greet them in Ewe they'll tell you, 'Oh I don't speak Twi'. "They cannot even identify their own mother language," he adds. In contrast, Mr Kambon is fluent in two West African languages - Akan and Yoruba - and is proficient in a third, Wolof. He also has some level of competency in Swahili, East Africa's main language, and in Kikongo, spoken in parts of southern and central Africa.

Campaigned against Gandhi

He has also tried to address the legacy of colonialism in other ways. In 2018, he successfully led a campaign to force the University of Ghana to remove a statue of India's independence leader Mahatma Gandhi.

"If we show that we have no respect for ourselves and look down on our own heroes and praise others who had no respect for us, then there is an issue," Mr Kambon tells the BBC. Although slavery was practised long before 1619, this year is widely regarded as the 400th anniversary of the first enslaved Africans arriving in the US. The Elmina and Cape Coast slave castles along Ghana's coastline served as a major hub for the trans-Atlantic trade where millions were captured and loaded onto ships, never to return home.   Media captionNancy Pelosi addresses Ghana's parliament

Timeline of slavery in the US:

1619 - Some of the first African slaves are purchased in Virginia by English colonists, though slaves had been used by European colonists long before 1788 - The US constitution is ratified; under it, slaves are considered by law to be three-fifths of a person 1808 - President Thomas Jefferson officially ends the African slave trade, but domestic slave trade, particularly in the southern states, begins to grow 1822 - Freed African Americans found Liberia in West Africa as a new home for freed slaves 1860 - Abraham Lincoln becomes president; the southern states secede and the Civil War begins the following year 1862 - President Lincoln's Emancipation Proclamation frees all slaves in the seceded states 1865 - The South loses the war; the 13th Amendment to the Constitution formally abolishes slavery 1868 - The 14th Amendment grants freed African Americans citizenship 1870 - The 15th Amendment gives African American men the right to vote; the South begins passing segregation laws Image copyrightSMITH COLLECTION/GADO Ghana's President Nana Akufo-Addo has declared 2019 to be the "Year of Return", saying it is the country's responsibility to "welcome home" Africans whose families were forced into slavery. The Ghana Tourism Authority has also planned a series of events - including a festival on 24 August - to showcase the beauty of the West African state in the hope of boosting tourism. Mr Kambon welcomes the initiative, but warns that Africans in the diaspora should not merely be seen as "automated teller machines".

Bastion of pan-Africanism

The president sees things differently, saying it is an opportunity to strengthen links and to give the diaspora a chance to explore the possibility of settling in Ghana - something that civil rights leaders Marcus Garvey and WEB Du Bois championed in the 1920s. Du Bois made Ghana his home, and died there in 1963 at the age of 95. He is buried in Accra. Martin Luther King, Malcolm X and Muhammad Ali all paid high profile visits to Ghana to reconnect with their African roots.
