That's funny

Why would 3 distinict regions join together to form one country?

The map perpetuates the lie imposed over a hundred years ago by European cartographers. They created straight line borders based on lines of lattitude and longitude. These places are largely desert. Tribes would have traditionally had areas where they traded, rested, grazed, etc. But these people were nomadic. They wouldn't have recognised (and indeed still don't recognise) these borders. It's only by the coast where you would have got fixed settlements.
