King Herod

Herod was a king appointed by the Romans ©
The Romans appointed King Herod as King of Judea in 37 BC. Historians agree that in many respects Herod had a hugely successful reign. King Herod, ethnically Arab but a practicing Jew, increased the land he governed from Palestine to parts of modern Jordan, Lebanon and Syria constructing fortresses, aqueducts and amphitheatres and earned him the title 'Herodes Magnus', Herod the Great.
The Romans also gave Herod the title 'King of the Jews' because of the Jewish population he ruled. The title of 'King of the Jews' begins to explain the impression we have of Herod from the Bible. The Bible shapes the popular conception we now have of Herod as a King who was proud of his title and would do anything to keep it. If the soothsayers of the time were correct, the birth of a new King of the Jews was imminent and threatened Herod's position. In the massacre of newborn babies of Bethlehem found in the Nativity story, King Herod is portrayed as a tyrant prepared to kill infants who could eventually challenge him.
However the historical evidence for the event is only Biblical and in fact only one verse in Matthew mentions it. The event is notably absent from the other gospels.
It seems difficult to imagine such a massacre was not mentioned by Josephus, a first-century historian who described other events in Herod's life. One could be a sceptical of Matthew's account of a massacre of infants.
In fact, demographic clues from first century Palestine reveal that Bethlehem was a small village, with a population between three hundred and a thousand. Experts estimate that, at any given time, the number of babies under the age of two would be only between seven and twenty. So numbers alone may be the reason why Josephus does not mention the murders.

Matthew 2:16 tells the story ©
Then Herod, when he saw that he was mocked of the wise men, was exceeding wroth, and sent forth, and slew all the children that were in Bethlehem, and in all the coasts thereof, from two years old and under, according to the time which he had diligently inquired of the wise men.Matthew 2:16
Many historians think that Herod's downfall begins with his possessive love for his wife Mariamme. On a political expedition he visits the Roman ruler Octavian in Rhodes and fears for his life (he had previously sided with the defeated Marc Antony). He demands that Mariamme is killed if he doesn't return alive, unable to bear the thought of another man with her.
Later he becomes convinced by his sister that Mariamme is scheming against him and she is put on trial and executed. Despite being responsible for her death, Herod's torment is intolerable. He sees visions of Mariamme. Perhaps in a futile attempt to replace his love for Mariamme, Herod becomes polygamous. The story of Herod becomes more tragic still when for fear of being usurped he executes three of his sons.
Herod's life was one of ruthless political expediency; although the historical evidence for the massacre of infants is exclusively Biblical it appears entirely possible that King Herod was capable of the atrocity.
