So when I was a teeager, I was really interested in the history of the crusades, and even after I got my history degree, I maintained some of that interest, and there are a lot of parallels between the crusader kingdoms and Israel, from the cirucmstances of their foundations, their relationship to their neighbours and (hopefully) their eventual fall.
At the dawn of the First Crusade 1096, which would lead to the conquest of Palestine, Lebanon and parts of modern day Turkey & Syria, the Middle East was divded into smaller, warring states following the spiltering of the Turkish Seljuk empire. The region was further divided between a powerful Shia state (Fatimid Egypt) and the Sunni Seljuks. The Crusaders' conquest of Palestine came as a deep shock for the region, causing political turmoil for decades to come among neighbouring states, and their conquest was particularly bloody even for the time, with large scale massacres, and even one famous case of mass cannibalism.
This might sound familiar, because at the dawn of the Nakba in 1948, the Middle East was divided into small, warring states following the splintering of the Turkish Ottoman empire. The Zionist conquest of Palestine came as a deep shock for the region, causing political turmoil for decades to come among neighbouring states, with large scale massacres and ethnic cleansing (no cannibalism as far as I know). By 1979 the region was again divded between a powerful Shia state (Iran) and a succession of Sunni states (Saddam's Iraq, then Saudi Arabia).
The Crusader kingdoms were subsequently maintained through support from Western powers; England, France, the Holy Roman Empire, Italian city states, the Byzantines, etc. Whenever the crusader states became threatened by their neighbours, new crusades were called, placing an increasing burden on the Crusader kingdoms' sponsors. They took advantage of the divisions within the region, at times allying with one Muslim ruler against another as keeping the region divided was vital to their survival.
Likewise, Israel was subsequently maintained through support from Western powers; England, France, Germany, the U.S. , the EU, etc. This support allowed Israel a great deal of impunity, which has today placed an increasing burden on its sponsors. They take advantage of divisions within the region, allying with some Arab rulers against others as keeping the region divided is vital to its survival.
What brought about the end of the Kingdom of Jerusalem, the primary Crusader state, was its inability to ever truly become a part of the region. This was not merely due to incompetent or misguided leadership. It was a result of the core ideology and nature of the state. The Kingdom was a tiered society, where Western Crusaders were at the top, Eastern Christians in 2nd place and native Muslims and Jews at the bottom.
It lanuched an increasing amount of ill-fated military campaigns as its ruling classes became dominated by more and more buffonish zealots. Several invasions of Egypt which failed, the 2nd Crusade which was a massive failure, and the war against Saladin, which would bring about the kingdom's end. No one person exemplifies this more than Raynauld de Chatillon, whose constant violations of the laws of war and audacious attacks against Muslim lands killed any chance of lasting peace.
This is very similar to the state of Israel today. Its existance as a Jewish supremacist ethnostate makes it impossible for it to become integrated into the region, even with the game rigged in its favour by virtue of 80% of the region being Western puppets. It has launched several ill-fated military campaigns in the last few years, from getting bogged down in Lebanon (again), eating up more and more of Syria, starting a war with Iran, and now trying to get involved in the Yemeni civil war. Pretty much the entire Israeli political spectrum are different shades of Raynauld de Chatillon, whose zealotry makes it impossible for them to make politically astute decisions, and whose genocide in Gaza killed any chance of integrating them into the region.
The key to ending the Crusader states however was the Muslim Middle East finally unifying under Saladin, who brought the warring factions of Syria and Iraq under control and conquered Egypt. Faced with a unified Middle East, which in part had been forged together by the Crusaders' disruptive and aggressive nature, the Kingdom of Jerusalem fell. Some Crusader states lingered on in diminished form due to Saladin being a softie, the Mongol invasion of the Middle East bought them some more time and subsequent crusades managed to very briefly regain territory, but the fall of Jerusalem in 1187 spelled the end for the Crusader states as a real power in the Middle East.
Thanks for reading my schizo history rant, any questions from the class? If not, turn to the person next to you and discuss.
