1192 CE
A year that saw the conclusion of the Third Crusade with a negotiated truce between Richard the Lionheart and Saladin, Richard's capture on his return journey, and the establishment of the Kamakura shogunate in Japan.
Geopolitics & Diplomacy
- Richard I and Saladin signed the Treaty of Jaffa on September 2, ending the Third Crusade with a three-year truce that granted Christians access to Jerusalem for pilgrimage but left the city under Muslim control.
- The treaty preserved a strip of Crusader-held coastline from Tyre to Jaffa, providing a territorial basis for the continued existence of the Kingdom of Jerusalem.
- Minamoto no Yoritomo was appointed Shogun by the Japanese emperor, establishing the Kamakura shogunate and inaugurating a system of military government that would dominate Japan for centuries.
Conflict & Security
- Richard I departed the Holy Land in October but was captured in December near Vienna by Duke Leopold V of Austria, who bore a grudge against him from the Siege of Acre.
- Conrad of Montferrat, who had been elected King of Jerusalem, was assassinated in Tyre in April by members of the Assassin sect, just days after his election.
Climate & Environment
- Atmospheric carbon dioxide concentration was approximately 275 parts per million, as later confirmed by ice core analysis.
Culture & Society
- The Third Crusade, though it failed to recapture Jerusalem, became the subject of extensive chronicling and legend, particularly around the figures of Richard the Lionheart and Saladin.
- The estimated world population was approximately 358 million.
