Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals. Finally, Homo sapiens ventured out of Africa around 100,000 years ago, spread across Asia around 60,000 years ago and arrived on new continents and islands since then.
Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts and more recently has been assisted by archaeogenetics. Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics.
The end of the Franco Prussian War resulted in the defeat of <em>France and subsequent loss of its territories of Alsace and Lorraine to the Germans</em>. This ended the balance of power that had existed in Europe since the Congress of Vienna in 1915.
<em>France was determined to regain its lost territories</em>. This caused Germany to form alliances with the Austro Hungarian Empire and reinforce its military. This period was the prelude to the First World War in 1914.
