Explorations in the Americas refer to the period of European exploration and colonization that began in the late 15th century, leading to the widespread contact between Europe and the indigenous peoples of the Americas. This era is marked by significant events such as voyages of discovery, claims to new territories, and the establishment of colonies, all of which played a crucial role in shaping global trade patterns, cultural exchanges, and geopolitical dynamics, particularly through the Columbian Exchange and the Spanish conquest.
