European colonizers were individuals and groups from various European nations, such as Spain, France, Britain, and Portugal, who explored and settled in other parts of the world from the 15th to the 20th centuries. Their primary motivations included the search for new trade routes, the spread of Christianity, and the desire for land and resources. These colonizers established colonies in regions like the Americas, Africa, and Asia, often leading to significant cultural exchanges, but also to conflicts and the exploitation of indigenous populations. The impact of their actions is still felt today in many societies around the world.
