organized Hyborian kingdom to emerge was Hyperborea. The tribe that established it entered their Neolithic age by learning to erect buildings in stone, largely for fortification. These nomads lived in tents made out of the hides of horses, but soon abandoned them in favor of their crude but durable stone houses. They permanently settled in fortified settlements and developed cyclopean masonry to further fortify their defensive walls. The Hyperboreans were by then the most advanced of the Hyborian tribes and set out to expand their kingdom by attacking their backwards neighbors. Tribes who defended their territories lost them and were forced to migrate elsewhere. Others fled the path of Hyperborean expansion before ever engaging them in war. Meanwhile, the apemen of the Arctic Circle emerged as a new race of light-haired and tall humans. They started their own migration to the south, displacing the northernmost of the Hyborian tribes. Rulers of the West For the next thousand years, the warlike Hyborian nations advanced to become the rulers of the western areas of the nameless continent. They encountered the Picts and forced them back to the western wastelands, which would come to be known as the "Pictish Wilderness". Following the example of their Hyperborean cousins, other Hyborians migrated Southward and created their own kingdoms. The southernmost of the early kingdoms was Koth, which was established north of the lands of Shem and soon started extending its cultural influence over the southern shepherds. Just south of the Pictish Wilderness was the fertile valley known as "Zing". The wandering Hyborian tribe which conquered it found other people already settled there. They included a nameless farming nation related to the people of the Shem and a warlike Pictish tribe who had previously conquered them. They established the kingdom of Zingara and absorbed the defeated elements into their tribe. Hyborians, Picts, and the unnamed kin of the Shemites would merge into a nation calling themselves Zingarans. On the other hand, at the north of the continent, the fair-haired invaders from the Arctic Circle had grown in numbers and power. They continued their expansion south while in turn displacing defeated Hyborians to the south. Even Hyperborea was conquered by one of these barbarian tribes. But the conquerors here decided to maintain the kingdom with its old name, merged with the defeated Hyperboreans and adopted elements of Hyborian culture. The continuing wars and migrations would keep the
