What do you know about the Ottoman Empire? Jem has an idea that many of our listeners will have only a couple of very basic ideas, and so in this week's fast five he goes into as much detail as five minutes will allow!

The Condensed History Gems podcast is a bi-weekly history podcast hosted by Greg Chapman, juggler and comedy entertainer from Condensed Histories (@condensedhist) and Jem Duducu, history writer of HistoryGems (@historygems). Each week we have a half hour discussion episode, as well as a shorter ‘Fast 5’ episode featuring one of the two. Subjects range through history, from pirates to Saxons, Vikings to Victorians, and Romans to the Cold War! Find out more about the podcast at www.condensedhistories.com/gems
