History often tells the tale of tough times. If we flip through its pages, we find that most eras are marked by struggle rather than peace. Consequently, one year stands out: 536 CE.
This was a year that shook the world. The cause? Likely a volcanic eruption, but the exact volcano remains uncertain. Some experts believe it could be Ilopango in El Salvador, while a 2018 study suggests the eruption may have originated in Iceland. Ice core samples show that the atmosphere was filled with volcanic particles, causing what we now call a “volcanic winter.” This event radically changed the climate from 536 to 540 CE.
The effects were swift and severe. Roman statesman Cassiodorus wrote in 538 CE about a dim, bluish sun that caused panic among people. Procopius, a historian, spoke of the dread felt when the sun appeared eclipsed by a foggy haze. This was not just a feeling; there was real evidence. For instance, tree rings in Denmark showed abnormally narrow growth during this period, indicating drastic climate changes.
Agricultural systems struggled. The temperature dropped, leading to crop failures. This year is thought to have kicked off the Late Antique Little Ice Age, with global temperatures dropping several degrees. Snow even fell in China during summer, while some regions faced droughts.
Misery followed. The Gaelic Irish recorded famines, and bubonic plague hit regions like the port of Pelusium in Egypt. Historians often regard 536 CE as one of the worst years to be alive, emphasizing its grim impact on several regions.
Michael McCormick, a historian, noted that within five years of 536, the Justinianic plague pandemic would devastate the Mediterranean. While many factors contributed to the Byzantine Empire’s decline, scholars believe that climate change and disease played critical roles.
As empires crumbled, we saw shifts. In Central Asia, harsh conditions pushed nomadic tribes east toward China. Ironically, some tribes that faced these hardships ended up helping to weaken the Persian Empire. Conversely, while some regions struggled, the Arabian Peninsula experienced increased rainfall, paving the way for the rise of a new power: the Arab Empire by the seventh century.
Today, we often hear about climate crises and their impacts through social media. The struggles of 536 CE remind us how interconnected our world can be. While some suffer, others may find opportunities. History tells us these stories, offering lessons that remain relevant even now.
