We’re down to the Final Four. Be sure to cast your vote for which should move on to next Friday’s final
After two rounds of intense voting, we have our Final Four. And, much like in Round One, we are (mostly) in agreement with how the people have thus far voted.
TV Receiver Patented over Nosferatu Released (29-5)
Japan Launches Purpose Built First Aircraft Carrier over Canadian Tire (21-11)
Vitamin D Isolated over First Steel Tape Measure (28-7)
Ottoman Empire Collapses over USSR Founded (20-14)
In this penultimate round, we have two tough matchups. We have a technological innovation against a medical/scientific discovery, and one Empire’s collapse against a purpose-built ship of, at the time, a budding Empire.
We have provided our thoughts on which we think are the most important, but which events make it to the finals is up to you.
You can vote by using the Twitter polls embedded herein, by sending us a DM (@theseangraham and @aaronboyes1), or an email to historyslam@gmail.com. Voting ends on Monday and the Enrico Palazzo Pre-Memorial Championship will go live next Friday, December 16.
Final Four
Ottoman Empire Collapses

Japan Launches First Purposefully Built Air Craft Carrier
Sean: Plot twist – I actually think the collapse of the Ottoman Empire is the more important of the two in this matchup. I know that goes against everything I have advocated for over the last 10 years (PLANES!), but that just goes to show how significant the Ottoman Empire and its demise was in human history.
A good way to think about the Ottoman’s comes from Alan Mikhail, who has suggested that if we look at history from an eastern rather than western perspective, we would find that the Muslim world was the driving force in global events for centuries. He argues that nations in Western Europe viewed things like colonial expansion as part of their larger struggle against Islam. Within a framework where containing the Ottomans was central, things like the slave trade, Protestant Reformation, and militarization are inextricably linked to the Empire. Mikhail has even gone so far as to argue that the Ottoman Empire made our modern world.






Sean: Around 1324 BCE,
In the spring of 2012, I was in Guelph, Ontario at a conference. What I thought would a typical couple days turned out to be a pretty important event in my life. Not only did it provide me with my favourite conference story, but it was there where I met several members of the Activehistory.ca editorial team. I don’t recall the specific circumstances, but at some point I strongly (obnoxiously) suggested that the site would greatly benefit from a podcast. As any wise person would, the response from the team was that if I felt that way, I should be the one to do it. From that conversation, the History Slam was born and over 10 years, we produced 221 episodes with nearly 300 guests.
