which empire did the whole coast of the mediterranean sea belong to
Mediterranean Sea Two of the most notable Mediterranean civilizations in classical antiquity were the Greek city states and the Phoenicians, both of which extensively colonized the coastlines of the Mediterranean. Later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum ("Our Sea"). For the next 400 years, the Roman Empire completely controlled the Mediterranean Sea and virtually all its coastal regions from Gibraltar to the Levant.
Backshore Sediments in this area are well-sorted and well-rounded. Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune.The sedimentary structures include parallel bedding and low-angle cross-bedding.
East–West Schism In 476, when the last emperor of the western part of the Roman Empire was deposed and the western imperial insignia were sent to Constantinople, there was once again a single Roman Emperor. However, he had little power in the West, which was ruled almost entirely by various Germanic tribes. In the opinion of Randall R. Cloud, the permanent separation of the Greek East from the Latin West was "the fundamental reason for the estrangement that soon followed between the Greek and the Latin Christians".[84]
Byzantine Empire In addition to a reassertion of Byzantine military power and political authority, the period under the Macedonian dynasty is characterised by a cultural revival in spheres such as philosophy and the arts. There was a conscious effort to restore the brilliance of the period before the Slavic and subsequent Arab invasions, and the Macedonian era has been dubbed the "Golden Age" of Byzantium.[83] Though the Empire was significantly smaller than during the reign of Justinian, it had regained significant strength, as the remaining territories were less geographically dispersed and more politically, economically, and culturally integrated.
