League Evolution and History
The journey of USL League One began with ten founding members who launched the first season in 2019. These early years established the league's footprint, blending established regional clubs with new professional ventures.
Between 2020 and 2022, the league underwent a significant transition following the departure of Major League Soccer (MLS) reserve teams, which moved to the newly formed MLS Next Pro. This shift opened the door for a first wave of independent expansion clubs, diversifying the league's ownership and regional reach.
From 2023 onward, the league entered a second wave of expansion. This growth has been characterized by the pseudo-promotion of clubs—a process where teams move up from the pre-professional USL League Two to the professional ranks of League One.
Competition and Honors
The league crowns two primary honors: the USL Cup (playoff champion) and the Players' Shield (awarded to the best regular-season team). While several clubs have tasted success, Union Omaha has emerged as a dominant force, holding the record for the most championships and Shields.
In addition to league-specific trophies, USL League One clubs compete in the U.S. Open Cup, the premier domestic knockout competition in the United States.
