Sarnia vs Empire

Informations

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.

An empire is a sovereign state consisting of several territories and peoples subject to a single ruling authority, often an emperor. States can be empires either by narrow definition through having an emperor and being named as such, or by broad definition as stated above in being an aggregated realm under the rule of a supreme authority. An empire can be made solely of contiguous territories, such as the Austro-Hungarian Empire or the Russian Empire, or include territories which are far remote from the 'home' country of the empire, such as a colonial empire. Aside from the more formal usage, the word empire can also refer colloquially to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss), or a group (political bosses). The concept of empire is associated with other such concepts as imperialism, colonialism, and globalization, with imperialism referring to the creation and maintenance of unequal relationships between nations and not necessarily the policy of a state headed by an emperor or empress. Empire is often used as a term to describe displeasure to overpowering situations.

There are two main ways to establish and maintain an imperial political structure: (i) as a territorial empire of direct conquest and control with force or (ii) as a coercive, hegemonic empire of indirect conquest and control with power. The former method provides greater tribute and direct political control, yet limits further expansion because it absorbs military forces to fixed garrisons. The latter method provides less tribute and indirect control, but avails military forces for further expansion. Territorial empires (e.g. the Mongol Empire and Median Empire) tend to be contiguous areas. The term, on occasion, has been applied to maritime republics or thalassocracies (e.g. the Athenian and British empires) with looser structures and more scattered territories, often consisting of many islands and other forms of possessions which required the creation and maintenance of a powerful navy. Empires such the Holy Roman Empire also came together by electing the emperor with votes from member realms through the Imperial election.
