The The Austro-Hungarian Compromise of 1867 happens late in this 45-minute video. Welcome to the confusing, shifting world of Europe. The Battle of Solferino in 1859 sticks in my mind because the suffering of the wounded inspired a businessman from neutral Switzerland to start the Red Cross. The revolutions of 1848 - multiple countries - are something to look into another day.

What else happened in 1867? Ontario, Quebec, and the old maritime provinces in British North America became Canada ("confederation"). U.S.A. bought Alaska from Russia, ending the North America part of the Russian Empire. Prince Mutsuhito took over as the Emperor Meiji of Japan, with the society-changing Meiji Restoration starting in 1868.

Do you remember the slick Winnipeg cat burglar? He stole the treasured Star of Empress Sisi.
 
 

Do you know anything at all about the war between Austria-Hungary and Serbia? The first 33 minutes are about this (the Battle of Tannenberg is unrelated). I remind you that the assassination of Austrian Grand Duke Franz Ferdinand in Sarajevo by a Serbian assassin set off the mousetrap leading to the Great War.

They made another presentation, "The Forgotten Battle That Destroyed The Hapsburg Empire", about a 1914-1915 siege battle.
 
 

This is a longer one at 52 minutes, but it sucks you in. There is a lot of century-old footage, plus some re-enactments. It fills out things you partly know.
