Civilization stateA civilization state, or civilizational state, is a country that aims to represent not just a historical territory, ethnolinguistic group, or body of governance, but a unique civilization in its own right. It is distinguished from the concept of a nation state by describing a country's dominant sociopolitical modes as constituting a category larger than a single nation. When classifying states as civilization states, emphasis is often placed on a country's historical continuity and cultural unity across a large geographic region.
Historiography of the fall of the Western Roman EmpireThe causes and mechanisms of the fall of the Western Roman Empire are a historical theme that was introduced by historian Edward Gibbon in his 1776 book The History of the Decline and Fall of the Roman Empire. Though Gibbon was not the first to speculate on why the empire collapsed, he was the first to give a well-researched and well-referenced account of the event, and started an ongoing historiographical discussion about what caused the fall of the Western Roman Empire.
Pre-modern human migrationThis article focusses on prehistorical migration since the Neolithic period until AD 1800. See Early human migrations for migration prior to the Neolithic, History of human migration for modern history, and human migration for contemporary migration. Paleolithic migration prior to end of the Last Glacial Maximum spread anatomically modern humans throughout Afro-Eurasia and to the Americas. During the Holocene climatic optimum, formerly isolated populations began to move and merge, giving rise to the pre-modern distribution of the world's major language families.
Berceau de la civilisationLe berceau de la civilisation est une expression faisant référence à des régions du monde où l'on considère que les premières civilisations humaines virent le jour. La théorie dominante est qu'il n'y a pas qu'un seul berceau, mais que plusieurs civilisations se sont développées de manière indépendante. Celles du Croissant fertile, de la période d'Obeïd en Mésopotamie et de la culture de Nagada en Égypte, sont considérées comme les plus anciennes.
