In 1453, a single mistake changed world history forever. For just 10 minutes, the gates of Constantinople were left open. That one moment allowed the Ottoman army to enter the city and end the Byzantine Empire after more than 1,000 years. History doesn’t always change slowly. Sometimes, it changes in minutes. Watch till the end for this unbelievable historical moment. #HistoryShorts #WorldHistory #UntoldHistory history shorts, world history, byzantine empire, fall of constantinople, ottoman empire, historical facts, untold history, ai history video, ancient history shorts
