During its first five years the Ford Motor Company produced eight different models, and by 1908 its output was 100 cars a day. The stockholders were ecstatic; Ford was dissatisfied and looked toward turning out 1,000 a day. The stockholders seriously considered court action to stop him from using profits to expand. In 1909 Ford, who owned 58 percent of the stock, announced that he was only going to make one car in the future, the Model T. The only thing the minority stockholders could do to protect their dividends from his all-consuming imagination was to take him to court, which Horace and John Dodge did in 1916.

The Dodge brothers, who formerly had supplied chassis to Ford but were now manufacturing their own car while still holding Ford stock, sued Ford for what they claimed was his reckless expansion and for reducing prices of the company’s product, thereby diverting money from stockholders’ dividends. The court hearings gave Ford a chance to expound his ideas about business. In December 1917 the court ruled in favour of the Dodges; Ford, as in the Selden case, appealed, but this time he lost. In 1919 the court said that, while Ford’s sentiments about his employees and customers were nice, a business is for the profit of its stockholders. Ford, irate that a court and a few shareholders, whom he likened to parasites, could interfere with the management of his company, determined to buy out all the shareholders. He had resigned as president in December 1918 in favour of his son, Edsel, and in March 1919 he announced a plan to organize a new company to build cars cheaper than the Model T. When asked what would become of the Ford Motor Company, he said, “Why I don’t know exactly what will become of that; the portion of it that does not belong to me cannot be sold to me, that I know.” The Dodges, somewhat inconsistently, having just taken him to court for mismanagement, vowed that he would not be allowed to leave. Ford said that if he was not master of his own company, he would start another. The ruse worked; by July 1919 Ford had bought out all seven minority stockholders. (The seven had little to complain about: in addition to being paid nearly $106,000,000 for their stock, they received a court-ordered dividend of $19,275,385 plus $1,536,749 in interest.) Ford Motor Company was reorganized under a Delaware charter in 1920 with all shares held by Ford and other family members. Never had one man controlled so completely a business enterprise so gigantic.

The planning of a huge new plant at River Rouge, Michigan, had been one of the specific causes of the Dodge suit. What Ford dreamed of was not merely increased capacity but complete self-sufficiency. World War I, with its shortages and price increases, demonstrated for him the need to control raw materials; slow-moving suppliers convinced him that he should make his own parts. Wheels, tires, upholstery, and various accessories were purchased from other companies around Detroit. As Ford production increased, these smaller operations had to speed their output; most of them had to install their own assembly lines. It became impossible to coordinate production and shipment so that each product would arrive at the right place and at the right time. At first he tried accumulating large inventories to prevent delays or stoppages of the assembly line, but he soon realized that stockpiling wasted capital. Instead he took up the idea of extending movement to inventories as well as to production. He perceived that his costs in manufacturing began the moment the raw material was separated from the earth and continued until the finished product was delivered to the consumer. The plant he built in River Rouge embodied his idea of an integrated operation encompassing production, assembly, and transportation. To complete the vertical integration of his empire, he purchased a railroad, acquired control of 16 coal mines and about 700,000 (285,000 hectares) acres of timberland, built a sawmill, acquired a fleet of Great Lakes freighters to bring ore from his Lake Superior mines, and even bought a glassworks.

The move from Highland Park to the completed River Rouge plant was accomplished in 1927. At 8 o’clock any morning, just enough ore for the day would arrive on a Ford freighter from Ford mines in Michigan and Minnesota and would be transferred by conveyor to the blast furnaces and transformed into steel with heat supplied by coal from Ford mines in Kentucky. It would continue on through the foundry molds and stamping mills and exactly 28 hours after arrival as ore would emerge as a finished automobile. Similar systems handled lumber for floorboards, rubber for tires, and so on. At the height of its success the company’s holdings stretched from the iron mines of northern Michigan to the jungles of Brazil, and it operated in 33 countries around the globe. Most remarkably, not one cent had been borrowed to pay for any of it. It was all built out of profits from the Model T.
