Hey guys, welcome to Hip Hughes History. World history on tap for you today. A huge, it's huge, it's huge turning point in world history. No, it's not the Crusades, it's not the Industrial Revolution, it's something you've probably never heard of before. It's the Columbian Exchange. And it's not going to just rock one world, it's going to rock two worlds, one of them to the ground. So why don't we take a look at the Columbian Exchange and see if we can't grow our brains as we do a little bit of the giddy up for the look.
