Final answer:
Nobles staying in Palestine post-Crusades managed their domains in a manner similar to the Muslim predecessors and maintained complex relations with local populations. They utilized Muslim administrative practices and stressed defense structures such as the Krak des Chevaliers, while their connection to Europe persisted through communications and resources. Trade and practical coexistence became priorities due to the diminished European settler presence and powerful Islamic neighbors.
Step-by-step explanation:
The nobles who decided to stay in Palestine after the crusades adapted to a new way of life due to the region's complex social and economic dynamics. Instead of imposing a completely foreign system, they organized their governance along familiar feudal lines but with local adaptations. The crusaders had to rely on cash or goods for taxation, reusing Muslim administration practices and employed Muslim scribes and interpreters because of the diverse population and languages. In addition, they built castles and fortresses such as the Krak des Chevaliers for defense with a limited number of soldiers. Many nobles and knights maintained connections with Europe, sending letters and resources, yet the lack of European settlers made it necessary for the Christians to preserve and not brutalize the native communities for lack of workers. The presence of influential Islamic states like the Mamluks and the Ottoman Turks in nearby regions, along with the diminishing effectiveness of the Crusades, led these nobles to focus on trade, and practical coexistence often overshadowed the lingering mistrust amongst religious and ethnic groups.
