It is a combination of factors, including new technology and the transformation of the American manufacturing economy, from producing war-related items to consumer goods at the end of World War II. By the end of the 1950s, one in six working Americans were employed either directly or indirectly in the automotive industry. The United States became the world's largest manufacturer of automobiles, and Henry Ford's goal of 30 years earlier—that any man with a good job should be able to afford an automobile—was achieved
The 1950s were pivotal for the American automobile industry. The post-World War II era brought a wide range of new technologies to the automobile consumer, and a host of problems for the independent automobile manufacturers. The industry was maturing in an era of rapid technological change; mass production and the benefits from economies of scale led to innovative designs and greater profits, but stiff competition between the automakers. By the end of the decade, the industry had reshaped itself into the Big Three, Studebaker, and AMC. The age of small independent automakers was nearly over, as most of them either consolidated or went out of business.
A number of innovations were either invented or improved sufficiently to allow for mass production during the decade: air conditioning, automatic transmission, power steering, power brakes, seat belts and arguably the most influential change in automotive history, the overhead-valve V8 engine. The horsepower race had begun, laying the foundation for the muscle car era.
Through the many wars and peace congresses of the 18th century, European diplomacy strove to maintain a balance between five great powers: Britain, France, Austria, Russia, and Prussia. At the century’s end, however, the French Revolution, France’s efforts to export it, and the attempts of Napoleon I to conquer Europe first unbalanced and then overthrew the continent’s state system. After Napoleon’s defeat, the Congress of Vienna was convened in 1814–15 to set new boundaries, re-create the balance of power, and guard against future French hegemony. It also dealt with international problems internationally, taking up issues such as rivers, the slave trade, and the rules of diplomacy. The Final Act of Vienna of 1815, as amended at the Congress of Aix-la-Chapelle (Aachen) in 1818, established four classes of heads of diplomatic missions—precedence within each class being determined by the date of presentation of credentials—and a system for signing treaties in French alphabetical order by country name. Thus ended the battles over precedence. Unwritten rules also were established. At Vienna, for example, a distinction was made between great powers and “powers with limited interests.” Only great powers exchanged ambassadors. Until 1893 the United States had no ambassadors; like those of other lesser states, its envoys were only ministers.
