A settler is someone who moves to a new, often undeveloped place with the intention of living there permanently and building a community. When American pioneers traveled west in covered wagons during the 1800s, they were settlers establishing new towns and farms in territories that lacked the roads, schools, and stores they'd known back east. The Pilgrims who arrived at Plymouth Rock in 1620 were settlers, building homes and planting crops in what was, to them, an unfamiliar land.

The word emphasizes permanence and building: settlers don't just visit or explore, they put down roots. They construct houses, plant gardens, start businesses, and create the foundations of towns and cities. Early settlers faced enormous challenges: clearing land, finding water, growing food, and surviving harsh weather without nearby stores or doctors.

Today, people use settler less commonly for modern migration, but the word still appears in history books and discussions about how communities formed. Science fiction writers imagine future settlers on Mars or distant planets, carrying forward that same spirit of building new lives in challenging places.

When settlers arrived in new lands, they often encountered Indigenous peoples who already lived there, which created complex situations involving cooperation, conflict, and competing claims to the same territory.
