The region was contoled by two state goverments, but the oil in the region was in the center. The center wasn't  inhabated until the oil was found. So, the goverment fought over it by war. Then the UN came in and took control of the oil. The oil now is controled by OPEC and Shipped from an OPEC harbor.

The goverments began to try to find more oil and they did. Another war came but the UN didn't intervean. The line was created and oil sources were divided. The major city on each side became the capital and some cities popped up near the oil fields.
