It’s in development at Amazon, and has been for a year, reports Nellie Andreeva at Deadline Hollywood:
It envisions an alternate history where newly freed African Americans have secured the Southern states of Louisiana, Mississippi and Alabama post-Reconstruction as reparations for slavery, and with that land, the freedom to shape their own destiny. The sovereign nation they formed, New Colonia, has had a tumultuous and sometimes violent relationship with its looming “Big Neighbor,” both ally and foe, the United States. The past 150 years have been witness to military incursions, assassinations, regime change, coups, etc. Today, after two decades of peace with the U.S. and unprecedented growth, an ascendant New Colonia joins the ranks of major industrialized nations on the world stage as America slides into rapid decline. Inexorably tied together, the fate of two nations, indivisible, hangs in the balance.
Another alternate history, in development at HBO, is called “Confederate,” envisioning a present-day US where the South achieved independence in the Civil War, and slavery survives as a modern institution.
