65. Egypt

Home of the camel since 525 BCE. Camels are responsible for a dispute over the world's only inhabitable unclaimed land. According to an 1899 boundary set by the British, the Bir Tawil region was part of Sudan. However, a 1902 map placed it in Egypt as their nomads used it for camel grazing. In exchange, the much more valuable Hala'ib Triangle was transferred to Sudan. Both Egypt and Sudan have backed their preferred map ever since, leaving Bir Tawil unclaimed.
