Year of Return
2019 was an important year throughout the African diaspora — the 400th year since enslaved Africans first arrived in the United States. In Ghana — once the center of the European slave trade — 2019 was declared "the year of return" and the start of a campaign to encourage descendants of enslaved Africans to re-connect with the land of their ancestors. Thousands of African-Americans made the trip to Ghana — and many have decided to stay. They're fed up with police brutality and systemic racism in the US, ready to build new lives in Africa — and their number is growing.
