Transcript of The Five Epochs of Metropolitan Evolution

The Five Epochs of Metropolitan Evolution By Callie and Hannah The Sail-Wagon Epoch From 1790 through 1820, this was the an Epoch of mainly overland (wagons and horses) and waterway (mostly sail boats) travel. During this time, the leading cities were northeastern ports which were heavily oriented to European trade overseas. Interior ports were still some-what accessible, but others were not. Leading cities in this time were New York, Boston, and Philadelphia. The Iron Horse Epoch This is the second stage of the five epochs from 1830 to 1870, which marks the beginnings of the Industrial Revolution in North America. Major development is introduced and spread of steam powered railroad occurs. A nationwide transportation system begins to develop around this time, and in 1869 the first transcontinental railroad is completed. Faster and easier transportation helps to foster industrialization. The coal industry grows and cheaper, easier transportation of raw materials allows manufacturing to develop westward from the East Coast. Pittsburgh, Detroit and Chicago were major cities during this time and New York City becomes a Primate City in 1830. The Steel Rail Epoch During 1870 to 1920, there was major advancement of the Industrial Revolution in North America. The development of the National metropolitan system occurs. Steel industry plays a major role in defining this epoch because all of the iron rails on train tracks are replaced by steel railings. This allows for traveling at higher speeds, the ability to carry heavier loads, and cheaper transportation costs. Major steel industries during this time were along the Chicago-Detroit-Pittsburgh axis. The Auto Air Amenity The Satellite Electronics-Jet Propulsion Epoch This is the epoch we are currently in. It began in 1970 at the end of The Auto-Air- Amenity Epoch. In the present epoch, we have the newest advances in information management, computer technologies, global communications, and intercontinental travel. This epoch favors globally-oriented metropolises. This epoch began in 1920 and ended in 1970. The maturation of national urban hierarchy occurred in this epoch along with the inventions of the airplane and automobile. These two inventions were the key elements. The new technology put the farmer in an automobile and thus encouraged the centralization of urban growth at the larger, more diversified centers in all of the commercial farming regions. There was also an expansion of white-collar services jobs, and the growing pull of amenities. This stimulated urbanization of the suburbs.
