Ford opened its new Highland Park, Michigan plant as a purpose-built, modern factory designed by architect Albert Kahn. The site soon became a major center for Model T production and for experiments in faster, more standardized work.
Ford put the Model T chassis onto a continuously moving line at Highland Park, bringing work to each worker instead of having workers move around a stationary car frame. This “moving assembly line” became a defining feature of the factory system, increasing output while also making work more repetitive and closely timed.
Ford more than doubled the minimum daily wage and paired it with a shorter workday, aiming to stabilize a workforce strained by fast-paced, repetitive assembly-line jobs. The move helped cut turnover and became a widely discussed example of how wages, productivity, and mass consumption could reinforce each other in industrial capitalism.
Ford acquired land along the River Rouge in Dearborn, Michigan, initially with plans unrelated to heavy industry. The purchase positioned the company to build a much larger, more integrated factory complex as demands and strategy shifted during World War I.
Ford began building what would become the River Rouge complex, designed largely by Albert Kahn, to expand beyond Highland Park’s multi-story layout. The Rouge was planned around one-level, continuous material flow and around “vertical integration,” meaning more steps—from raw materials to finished vehicles—could happen under Ford’s control.
During World War I, Ford built Eagle Boats (submarine-chaser ships) at the Rouge, applying factory-style methods to naval production. The project showed both the appeal and the limits of mass-production approaches when workers and managers faced unfamiliar, complex manufacturing tasks.
A key step toward Rouge “vertical integration” was on-site steelmaking, reducing reliance on outside steel suppliers. The opening of a blast furnace at the Rouge helped Ford move closer to its goal of turning incoming raw materials into finished parts and vehicles within one complex.
After the war, the Rouge became a major site for Fordson tractor production, linking industrial methods to agricultural mechanization. Tractors were well-suited to assembly-line work, and their volume helped keep the Rouge operating as the complex expanded through the 1920s.
Ford added major materials-processing capacity at the Rouge by building an automotive glass plant designed by Albert Kahn. This expanded the complex’s ability to make key components internally, strengthening the Rouge model of tightly connected production stages in one location.
Ford moved its automotive factory workers to a five-day, 40-hour week, a major labor-policy shift for a large manufacturer. The change reflected a growing belief that shorter hours could support productivity and reduce turnover while reshaping expectations about industrial work time.
Ford ended Model T production after nearly two decades, marking the closing of the company’s first mass-market era centered on Highland Park methods. The shutdown highlighted a factory-system reality: changing products at scale often required stopping lines and retooling entire plants.
Ford introduced the Model A as the Model T’s replacement, and it became the first Ford car assembled at the Rouge complex. This shift signaled a new production phase: the Rouge’s integrated, one-level layout increasingly replaced Highland Park as Ford’s flagship approach to high-volume manufacturing.
By 1928 the Rouge complex was largely complete, with dozens of specialized buildings, internal rail and dock facilities, and major materials-processing operations. It became a well-known example of the factory system at peak scale, where production was organized as a coordinated flow across many linked processes.
During the Great Depression, thousands of unemployed workers marched to the Rouge with demands for jobs and relief. Police and Ford security responded with tear gas and gunfire, killing marchers and wounding many others, intensifying public debate over industrial power, policing, and workers’ rights.
Ford introduced a new low-priced V-8 engine for 1932, and Rouge production supported manufacturing the new powertrain at scale. The change illustrates how factory-system strengths—standard parts, specialized machines, and coordinated supply—helped Ford shift to more complex products while keeping prices competitive.
As union organizing intensified in the auto industry, United Auto Workers (UAW) organizers tried to distribute leaflets near the Rouge and were attacked by Ford security. Photographs and reporting from the incident damaged Ford’s public image and became a key moment in the long struggle over unionization at the Rouge.
The Rouge continued to grow beyond its 1920s core, including major additions such as a large tire plant designed by Albert Kahn. Expansion during the late 1930s shows how the factory system remained dynamic, with new buildings added to control more inputs and meet changing production needs.
As the U.S. prepared for possible entry into World War II, Ford’s large-scale production experience at Highland Park and the Rouge shaped how the company and government thought about rapid industrial expansion. By 1941, the emphasis shifted toward wartime output, marking the end of the interwar chapter when these plants primarily defined Ford’s civilian factory system.
