Title: Pacific Division (NHL)
Passage: The National Hockey League's Pacific Division was formed in 1993 as part of the Western Conference in a league realignment.  It is also one of the two successors of the Smythe Division (the other one was the Northwest Division), though of the current teams, only the Anaheim Ducks and Vegas Golden Knights did not play in the Smythe Division (the Arizona Coyotes played in the Smythe as the original Winnipeg Jets).  Due to subsequent realignments, three of the Pacific Division's original teams (the Calgary Flames, Edmonton Oilers, and Vancouver Canucks) left the division in 1998 but returned in 2013.  The division is currently the only one in the NHL without any Original Six teams.
