Q:Information: - Theophylact Simocatta ( Greek : ( ) Theophylaktos Simokat ( t ) es ) was an early seventh - century Byzantine historiographer , arguably ranking as the last historian of Late Antiquity , writing in the time of Heraclius ( c. 630 ) about the late Emperor Maurice ( 582 -- 602 ) . - Late Antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe, the Mediterranean world, and the Middle East. The development of the periodization has generally been accredited to historian Peter Brown, after the publication of his seminal work "The World of Late Antiquity" (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (c. 235 284) to, in the East, the early Islamic period (7th9th centuries), following the Muslim conquests in the mid7th century. In the West the end was earlier, with the start of the Early Medieval period typically placed in the 6th century, or earlier on the Western edges of the empire. - Heraclius (' c. 575 February 11, 641) was the Emperor of the Byzantine Empire from 610 to 641. - The Crisis of the Third Century, also known as Military Anarchy or the Imperial Crisis (AD 235284), was a period in which the Roman Empire nearly collapsed under the combined pressures of invasion, civil war, plague, and economic depression. The Crisis began with the assassination of Emperor Severus Alexander by his own troops in 235, initiating a 50-year period in which there were at least 26 claimants to the title of Emperor, mostly prominent Roman army generals, who assumed imperial power over all or part of the Empire. The same number of men became accepted by the Roman Senate as emperor during this period and so became legitimate emperors. - In the history of Europe, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. - The Roman Empire (Koine and Medieval Greek: , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic. - Classical antiquity (also the classical era, classical period or classical age) is a term for a long period of cultural history centered on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome, collectively known as the Greco-Roman world. It is the period in which Greek and Roman society flourished and wielded great influence throughout Europe, North Africa and Southwestern Asia. - The Middle East is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is "Middle-Eastern" and the derived noun is "Middle-Easterner". The term has come into wider usage as a replacement of the term Near East (as opposed to Far East) beginning in the early 20th century.
