Background and detail

Background. Michael D. Jones proposed a Welsh colony in Patagonia to preserve language and culture, observing that Welsh immigrants in the United States assimilated quickly. He recruited settlers and secured financing, choosing Patagonia for its isolation and the Argentine government's offer of land along the Chubut River in exchange for settling the unconquered area.

Arrival. In 1865, 153 Welsh settlers arrived aboard the clipper ship Mimosa. The Argentine government granted them land along the Chubut River. Upon reaching the valley, their first settlement was a small fortress on the site that later became the town of Rawson, the capital of Chubut Province.

Settlement. The settlers established Argentina's first irrigation system based on the Chubut River, creating fertile wheatlands. The first houses, constructed from earth, were washed away by a flash flood in 1865, leading to the construction of superior quality replacements. The settlement was located on Indigenous Tehuelche land.
