First gaining notoriety as the "shoe city," Brockton grew and flourished toward the end of the 19th century. As the halcyon days of the shoe industry waned, however, Brockton experienced many changes. After World War II, major residential development took place in the form of affordable single-family homes, and four new junior high schools and (eventually) a new high school were built. Housing for senior citizens and low-income residents was constructed, and new commercial buildings replaced those from a bygone era. Today, the city is still transforming as former shoe factories and commercial blocks are preserved and rehabilitated into new usage—whether residential, commercial, or industrial. Once a one-industry town, Brockton today is diverse in its industry and its people as it continues to be the "City of Champions."
