Throughout the late Middle Ages and beyond, England was a relatively stable and prosperous nation, largely free from the petty conflicts and power struggles of most of Western Europe. This stability was due to a multitude of factors affecting the nobility, but only one that truly affected the population at large: a stable and constant food supply. How was this possible? It can be attributed to a multitude of factors, but I believe one stands out above the others: the multitude of unique individuals, including luminaries such as Jethro Tull, who introduced new agricultural methods to Britain. These methods increased crop yields and thus improved the overall health, stability and tranquility of feudal and post-feudal peasants. There is, however, a period of growth that encompasses nearly all major innovations, as well as the lifespans of many luminaries. This period is commonly known as the British Agricultural Revolution. However, calling it the British Agricultural Revolution is a misnomer because most revolutions, such as the Industrial Revolution or the Scientific Revolution, take place over a period of relatively few years, certainly less than a century. However, the British agricultural revolution took place over the course of centuries, roughly from the 15th to the 19th century. Therefore, since it has evolved rather than rotated, I would not call it a revolution but rather an evolution....... middle of paper......But what about those who didn't succeed? Fortunately, the 20th century, with its cheap, oil-fueled steel and iron “horses,” solved the problem by creating a single tractor capable of performing almost all the tasks required of a small farmer. The first petrol tractors were hugely successful and in 1920 it was rare to find a farm without one. These tractors paved the way for future developments in agricultural and fertilizer technology, eventually enabling the production of modern, computerized, GPS-equipped tractors and combines..
