How did the Crusades help one class of people to become wealthy?

The Crusades significantly boosted trade between Europe and the East, leading to increased wealth for merchants and the emerging middle class. As European armies traveled and established connections in the Holy Land, they brought back valuable goods such as spices, textiles, and precious metals. This influx of trade not only enriched individual merchants but also stimulated the growth of towns and commercial centers, further enhancing the economic power of the burgeoning merchant class. As a result, the Crusades played a crucial role in shifting wealth and influence away from feudal lords to these new economic actors.
