The potato was introduced to Europe from the Americas as a result of Spanish colonization, and it quickly became a staple crop in many European countries due to its hardiness, nutritional value, and ability to feed many people with relatively little land. The importation of the potato is credited with helping to reduce famine in Europe and increase population growth, making it one of the most significant crops to be spread from the Americas during this time.
