We're pleased to release another beautiful Crash Course poster, brought to you by the folks at Thought Café. Mount this timeline on your wall to help you trace the events and ideas that changed the land we call America - from an untamed wilderness inhabited by Native Americans, to the modern superpower it is today.

Think of each episode as a stop along the road towards today, beginning with the arrival of Spanish explorers in the 16th century, and finishing with the presidency of Barack Obama, taking only a brief intermission for a Hot Dog eating contest. See if you can spot all the pop-culture characters, and find all 18 Uncle Sams!
