Volcanic eruption in Alaska may have helped end the Roman Republic: study

The video discusses a volcanic eruption in modern-day Alaska around 44 BC, which may have contributed to the Roman Republic's downfall. The study, published in the Proceedings of the National Academy of Sciences, reveals that the eruption left a large crater in Mount Ockmark. Led by Joe McConnell, the research team suggests the eruption caused environmental changes that destabilized the region, paving the way for the Imperial system after Julius Caesar's assassination. The eruption coincided with extreme cold, crop failures, and famines. Scientists used tree rings and tephra to date the eruption, supporting the hypothesis of its occurrence in Alaska.
