The demand for industrial labor to manage railroad operations brought workers and their families from all around the world to Pocatello through the first half of the 20^th century. Most of them settled in a neighborhood just east of the rail yards, now known as “the Triangle.” They created a vibrant, diverse community that helped to make Pocatello distinct in the eyes of many observers, and their families continue to shape local stories. This presentation examines who came, when and why, and the multiple obstacles and opportunities they faced in order to consider their unique role in Idaho and their place in the larger national story.
