History:

They were encountered by the crew of the USS Voyager, when the ship accessed a Hirogen controlled communications array in order to transmit to Earth. A Hirogen hunting vessel subsequently captured members of Voyager's crew.  Voyager was able to free the crewmembers, and was also able to use the array to receive over a hundred messages from the Federation.
  Voyager itself was later captured by the Hirogen who greatly extended the holodecks and forced the crew to participate in a variety of combat-related scenarios.  Eventually the Voyager crew were able to force a stalemate with the Hirogen, and a ceasefire was agreed. The Hirogen agreed to leave the ship in return for Holodeck technology.
