"What is so important about the year 1215? There are some history buffs who may be able to tell you that 1215 is the year the Magna Cartawas signed, but there are even fewer who know that King John of England's acceptance of this charterwas only one of four major, world-changing events of this significant year. In fact, the social, cultural, political, geographical, and religious shifts that occurred in this year alone had such a huge impact on the entire world, it warrants an entire course of study for anyone truly interested in the pivotal points of history that brought us to where we are now.As it turns out, the year 1215 was a major turning point in world history. Although the drafting of the Magna Carta is perhaps the most well-known event of 1215, anyone in Europe at the time would have told you the meeting of the Church's Fourth Lateran Council was much more significant. Meanwhile, in Asia,a Mongol ruffian named Genghis Khan was embarking on a mission for world domination, beginning with his success at the Battle of Beijing, while Islam was experiencing a Golden Age centered around Baghdad's House of Wisdom. Other cultures and societies around the globe were also experiencing pivotal moments in their development-from the Americas to Africa and Asia and beyond.These seismic events were only possible thanks to a confluence of global conditions, starting with the climate. Although we might not be familiar with the specifics, the ripple effect from these events can still be felt all over the world today.
