Herod I or Herod the Great (c. 72 BCE – c. 4 BCE) was a Roman Jewish client king of the Herodian Kingdom of Judea. He is known for his colossal building projects throughout Judea. Among these works are the rebuilding of the Second Temple in Jerusalem and the expansion of its base—the Western Wall being part of it. Vital details of his life are recorded in the works of the 1st century CE Roman–Jewish historian Josephus.
