History
Franklin was incorporated as a city in 1956, having grown from a rural township that was established in the mid-19th century as European settlers moved into Milwaukee County. For much of its early history, the area was characterized by farmland and agricultural activity, with its transformation into a residential suburb accelerating significantly during the post-World War II population expansion in the Milwaukee metro area. Over the decades, Franklin has evolved from a largely agricultural community into a full-service city with modern infrastructure, commercial development, and a growing population base.

Despite being part of densely populated Milwaukee County, Franklin retains a surprisingly generous amount of open land and green space relative to its neighbors, a distinction that stems from its large 34.71-square-mile footprint. This combination of suburban development and preserved natural character gives Franklin a distinctive identity that sets it apart from many of the more densely built communities in the Milwaukee metropolitan area.
