Cultural Changes – Western religion, education, and language were introduced, sometimes at the cost of traditional customs and beliefs.3. Rise of Nationalism – Colonial rule sparked resistance and nationalist movements, eventually leading to independence.4. Economic Reorientation – Local economies were changed to suit the needs of colonizers, focusing on export crops and raw materials.5.
