From the frozen forests of Germania to the walls of Constantinople, the Roman Empire once ruled the Mediterranean world without rival. Yet even the greatest empire in history could not escape decline. In this documentary, we explore how the Roman Empire lost every province it once controlled, region by region. Beginning with the Battle of Teutoburg Forest and ending with the Fall of Constantinople in 1453, this video traces the complete territorial collapse of Rome. We examine the true causes behind Rome’s downfall— civil wars, corruption, religious conflict, economic collapse, reliance on mercenaries, barbarian invasions, and political instability. From the fall of the Western Roman Empire in 476 to the slow erosion of Byzantine power after Manzikert and the sack of Constantinople in 1204, this is the full story of Rome’s shrinkage. This is not just how Rome fell— it is why empires collapse. 📌 Topics covered: Crisis of the Third Century Barbarian invasions & mercenary armies Fall of the Western Roman Empire (476) Justinian’s reconquests Muslim conquests of the Eastern Empire Battle of Manzikert (1071) Sack of Constantinople (1204) Ottoman conquest & Fall of Constantinople (1453) #RomanEmpire #FallOfRome #RomanHistory #ByzantineEmpire #AncientHistory #HistoryDocumentary #CollapseOfEmpires #Constantinople #Manzikert #Justinian #WesternRomanEmpire #EasternRomanEmpire #HistoryExplained
