European missionaries were individuals, often affiliated with religious organizations, who traveled to different parts of the world to spread their faith. Primarily during the 15th to 20th centuries, they aimed to convert indigenous populations to Christianity, often establishing schools, churches, and hospitals in the process. These missionaries played a significant role in cultural exchanges, sometimes leading to the introduction of European languages and customs. However, their efforts were also linked to colonialism, as they often operated in regions where European powers sought to expand their influence, impacting local traditions and societies.
