Give John Green 40 weeks, and Green will give you a playful and highly visual crash course in world history, taking you from the beginning of human civilization 15,000 years ago through to our modern age. If you're not familiar with him, Green is a bestselling author of several young adult books (Looking for Alaska, An Abundance of Katherines, and Paper Towns). He's also part of the popular vlogbrothers and an active Twitter user with more than 1.1 million followers -- that's about 22 times what we have, to put things in perspective.
The series starts with The Agricultural Revolution (above) and the Indus Valley Civilization (below). New video installments will be released throughout the year here. And more university-level history courses can be found in our big collection of 1,300 Free Courses Online.
