What was similar to the crusaders?

The Crusaders were similar to various military and religious movements throughout history that sought to expand their influence through warfare in the name of faith. For instance, the Spanish Reconquista aimed to reclaim the Iberian Peninsula from Muslim rule, paralleling the Crusaders' objectives in the Holy Land. Additionally, the Mongol invasions, while not religiously motivated, shared the characteristic of aggressive expansionism, impacting vast regions and cultures. Both the Crusaders and these movements were driven by a mix of religious zeal and political ambition.
