Crusades In The Levant, 1096 To 1291 [EPUB ebook] 

Crusade is called any of the Christian-inspired military movements from Western Europe to the Holy Land (the name Christians called Palestine) and the city of Jerusalem to conquer, occupy, and keep them under western European rule. Several reasons contributed to the failure of the Crusades, including: Europeans were a minority among a generally hostile population; oppression of the native population made the domain increasingly controversial; and the various struggles among the Christians themselves have also weakened them. Since the Persian Empire reinstated a Jewish state in Palestine – after its Diaspora by the Assyrians and Babylonians – through the Empire of Alexander and successors to the Roman Empire, there has always been a political-religious space for the descendants of Jacob (Israel). In the simulation it will be sought to establish and maintain a Crusader state territory (kingdom) in the Levant, more or less in accordance with the integration of biblical Israeli tribes maps from 1200 BC, the UN partition of Palestine in 1947 AD and the physical geographical area – like a stronghold based on safe boundaries.
