The 55 Most Important Events in Human History

For those who don’t have time to wade through the entire Timeline of Human History, I have created a list of the Most Important Events in Human History by collecting and combining several lists of 10, 25, 50 or 100 “most important events” or “events that changed the world” from the Internet and combining them into one meta-list, which is presented below in chronological order.  As with many such lists, the results are unlikely to win universal approval.  For example, I find the list biased toward Western (in particular American) civilization and overly focused on war, religion and dead white men.  There is also a bit of “comparing apples to oranges” because some of the important events happened in an instant and others occurred over many years or decades.  Despite these caveats, I think it is safe to say that all the events listed here are important to understanding human history.  For a much fuller picture, check out the world history timeline: Part 1: Prehistory to 1499, Part 2: 1500-1799, Part 3: 1800-1899, Part 4: 1900-Present.
