Explain why AD 476 is often used as its end date and how the Eastern Roman Empire continued for centuries, with Constantinople falling in AD 1453. Subject: History · Area: Ancient Greece & Rome · Ages 9 to 11 Page: https://lightmysky.com/learn/history/fall-of-the-western-roman-empire-mt_H4bLNkDrGJ ## Ready when they can - Name at least two reasons why the Western Roman Empire declined and fell - State that Romulus Augustulus was removed in AD 476 and that this is often used as the Western Roman Empire's end date - Explain that the Eastern (Byzantine) Empire survived for nearly 1,000 years after the West fell ## Lesson: Why the Western Roman Empire Fell We now return to Roman government. Emperors ruled many lands. Later, eastern and western parts had their own emperors. The West lost land and control over many years. Problems overlapped: attacks strained armies; rival leaders used troops and money fighting for power. Lost land meant less tax money to pay soldiers. Long borders left many places to defend, and troops could not guard them all at once. Historians debate how much each problem mattered. *(drawing: These problems could overlap and make each other worse. The boxes are a list, not a timeline.)* **Example.** In AD 476, a commander named Odoacer removed Romulus Augustulus, the young emperor ruling in Italy. Historians often use this event as the end of the Western Roman Empire. It marks a change in government. It does not mean that Roman towns, roads and ways of life all disappeared that year. *(drawing: These are usual end-date markers. The boxes show date order, not the length of time between them.)* The Eastern Roman Empire, later called Byzantine, continued for centuries as its lands and government changed. Its capital, Constantinople, fell to the Ottomans in AD 1453. To find a gap between AD dates, subtract the earlier year from the later year. For practice, AD 400 to AD 680 gives 680 - 400 = 280 years. To round 280 to the nearest hundred, compare 200 and 300. It is 80 from 200 and 20 from 300, so use 300. **Recap.** Several problems weakened the West over many years. AD 476 is its usual end-date marker. The Eastern Empire continued for centuries, with Constantinople falling in AD 1453. *Original learning material written for this dataset.
