Assyrian power has declined since the death of Tukulti-Ninurta I around 1208 BCE, but is to be restored briefly in the eleventh century BCE by Tiglath-pileser I, the son of Ashur-resh-ishi I, who ascends the Assyrian throne in 1115 BCE at a time when a people known as the Mushki, or Mushku, are thrusting into Asia Minor (now Turkey).

Their invasion constitutes a serious threat to Middle Eastern civilization because Asia Minor is the principal source of iron, which was now coming into general use.
