      Properties and assignments

      A label’s definition and the evidence for assigning it here are separate.

      Likely Unrelated to the Initial c.1200 BCE Crisis
      What does this label mean?

      Chronology or mechanism makes the event an unlikely initiator of the main collapse-period developments, though later effects may remain possible.

      Full property definition

      Why does this record have this property?

      The currently preferred Hekla 3 date is too late to initiate most destructions and political failures clustered around the turn of the twelfth century BCE.
