Map from a Re-written History

For my CS presentation I am looking at the making of coherent worlds, I feel that the best coherent worlds are those that have there roots based in reality. I saw this post and thought it was a good example of a map as well as an example of world building. The map below shows Africa as if it were ruled by the natives without Europe claiming the top half, so the countries all have original african names. The idea of Alternative Histories really interests me, as well as alternative realities such as Avatar and Alien which I will be looking at for my presentation.

There's a great novel from Kim Stanley Robinson called The Years of Rice and Salt. It's a really good alt-history "what if" novel. The basis synopsis is below:

 The Years of Rice and Salt  
It is the fourteenth century and one of the most apocalyptic events in human history is set to occur: the coming of the Black Death. History teaches us that a third of Europe's population was destroyed. But what if? What if the plague killed 99 percent of the population instead? How would the world have changed? This is a look at the history that could have been - a history that stretches across centuries, a history that sees dynasties and nations rise and crumble, a history that spans horrible famine and magnificent innovation. These are the years of rice and salt.
This is a universe where the first ship to reach the New World travels across the Pacific Ocean from China and colonization spreads from west to east. This is a universe where the Industrial Revolution is triggered by the world's greatest scientific minds - in India. This is a universe where Buddhism and Islam are the most influential and practised religions and Christianity is merely a historical footnote.
Through the eyes of soldiers and kings, explorers and philosophers, slaves and scholars, Robinson renders an immensely rich tapestry. Rewriting history and probing the most profound questions as only he can, Robinson shines his extraordinary light on the place of religion, culture, power, and even love on such an Earth. From the steppes of Asia to the shores of the Western Hemisphere, from the age of Akbar to the present and beyond, here is the stunning story of the creation of a new world.
