Black Panther is about a futuristic society that avoided the calamities of European colonialism and thus, through control of their own resources and technological innovation, its people were able to thrive and far exceed the progress of other global societies.

While this is fictional (a brand of storytelling called Afrofuturism), it reflects a way of considering the role of contingency in the past (e.g. how could things have been different).

Embracing this approach (but with a more historically-based approach), how might things have been different in Haiti if foreign countries had not insisted on intervening on a near-constant basis. You can use traditional narrative or tell a fictional story about the place that would exist.
