Why European nations conquered foreign lands?

European nations conquered foreign lands primarily for economic gain, driven by the desire for new resources, trade routes, and wealth accumulation. The Age of Exploration, fueled by advancements in navigation and maritime technology, allowed them to establish colonies and exploit local populations. Additionally, the spread of Christianity and national pride played significant roles in justifying their expansionist ambitions. Ultimately, these conquests significantly reshaped global dynamics and established colonial empires.
