when did the early middle ages start and end
Early Middle Ages The Early Middle Ages or Early Medieval Period, typically regarded as lasting from the 6th century to the 10th century CE, marked the start of the Middle Ages of European history. The Early Middle Ages followed the decline of the Western Roman Empire and preceded the High Middle Ages (c. 10th to 13th centuries). The Early Middle Ages overlap with Late Antiquity. The term "Late Antiquity" is used to emphasize elements of continuity with the Roman Empire, while "Early Middle Ages" is used to emphasize developments characteristic of the later medieval period.
Middle age According to the Oxford English Dictionary middle age is between 45 and 65:[2] "The period between early adulthood and old age, usually considered as the years from about 45 to 65." The US Census lists the category middle age from 45 to 65. Merriam-Webster lists middle age from 45 to 64,[3] while prominent psychologist Erik Erikson saw it starting a little earlier and defines middle adulthood as between 40 and 65. The Collins English Dictionary lists it between the ages of 40 and 60,[4] and the Diagnostic and Statistical Manual of Mental Disorders – the standard diagnostic manual of the American Psychiatric Association – used to define middle age as 40 to 60, but as of DSM-IV (1994) revised the definition upwards to 45 to 65.
