Background and Institution
The NHL has had a presence in Las Vegas since 1991; this calendar year, the town hosted the very first outdoor game between two NHL teams — a preseason exhibition between the Los Angeles Kings and New York Rangers outside Caesars Palace. The Kings would subsequently organize”Frozen Fury” — a collection of annual preseason matches in Las Vegas from the Colorado Avalanche. The NHL Awards ceremonies are held in Las Vegas since 2009.  In 2009, the media speculated about a plan involving Hollywood producer Jerry Bruckheimer to maneuver the Phoenix Coyotes to Nevada. 
Rumors of a vegas expansion team surfaced in August 2014, pointing into a new indoor stadium on the Strip (constructed as a joint venture between Anschutz Entertainment Group, owners of the Los Angeles Kings, and MGM Resorts International) as the possible home arena, although these rumors were refused by the league.  In November 2014, an unconfirmed report stated that the league had chosen billionaire businessman Bill Foley and the Maloof family (former owners of the National Basketball Association’s Sacramento Kings, and founders of the Palms Casino Resort) to lead the ownership group for a Las Vegas expansion team.  In December 2014, the NHL’s board of governors decided to permit Foley to hold a season ticket push to judge interest at a Las Vegas group, though league commissioner Gary Bettman also warned the press to”[not] make more out of this than it’s”.  The season ticket drive started in February 2015, with interested parties placing ten percent deposits to the 2016–17 season.  The driveway brought 5,000 deposits in its very first day and a half, and reached its aim of 10,000 deposits by April 2015. 
In June 2015, the team officially opened the window to get potential owners to bid on growth teams. With this point, Foley had procured more than 13,200 season-ticket deposits. Two growth applications were filed: Foley’s program for a Las Vegas group, and a bidding from Quebecor to revive the Quebec Nordiques at a brand new arena in Quebec City. Both Las Vegas and Quebec were invited to move into Stage II of this league growth bid in August 2015, and subsequently advanced to Stage III.
At the league owners’ meeting on June 22, 2016, in Las Vegas, the Las Vegas expansion bid was accepted with a unanimous vote, with play to start in the 2017–18 NHL season.  The group became the first major professional sports franchise to be established in Las Vegas, and also the very first NHL expansion team since 2000.  Foley committed to pay the league’s $500 million expansion fee and began the process of employing the group’s principal staff and determining its own official identity. Foley declared that former Washington Capitals general manager George McPhee are the franchise’s first general manager.  On November 22, 2016, the name was revealed as the Vegas Golden Knights.
Start of operations: 2017–present On March 1, 2017 (coinciding with the league’s trade deadline), the group completed its growth fee payments and filings, making it eligible to formally start operations like free agent acquisition, and involvement in league meetings.  Five days later, the Golden Knights made their first employees move by registering Reid Duke to a three-year entry-level contract. 
Gerard Gallant coaching the Golden Knights throughout their inaugural 2017–18 year old. Gallant was named as the head coach in April 2017.
The team announced inaugural head coach Gerard Gallant on April 13, 2017.  Over the next two weeks, the Golden Knights developed their plantation system, announcing affiliations with the Chicago Wolves of the American Hockey League and the Quad City Mallards of the ECHL. 
The group engaged in the 2017 NHL Expansion Draft on June 21, 2017, choosing an available player from all 30 teams in the NHL. The draft selections were announced at T-Mobile Arena during the NHL Awards ceremony. Some notable selections included goalie Marc-Andre Fleury in the Pittsburgh Penguins and winger James Neal from the Nashville Predators. At the 2017 NHL Entry Draft, Cody Glass was the first player chosen by the Golden Knights. The Golden Knights played their first game on October 6 against the Dallas Stars with Neal scoring the franchise’s first two goals en route to their first success. 
The group’s inaugural home game was played on October 10, 2017, hosting the Arizona Coyotes since the second game of a home-and-home series. In the aftermath of the October 1 mass shooting, the pre-game ceremonies honored the victims of this attack, along with the group issued an appeal for donations to its charitable arm.  With their 52 triumph, the Golden Knights improved their unbeaten streak to begin the year to 3–0, an NHL record for an expansion team.  The Golden Knights would be the first team in NHL history to have begun their inaugural season winning eight of the first nine matches. During their tenth match, goaltender Oscar Dansk was injured getting the next Golden Knights’ goaltender to be injured during the season after losing starters Fleury along with the recently obtained Malcolm Subban, forcing the group to begin a fourth goaltender in 11 matches with Maxime Lagace.  Fifteen games into the season, Vadim Shipachyov became the first player to retire in the NHL as a Golden Knight when he decided to return to the Kontinental Hockey League. Back in December, the Golden Knights put another NHL expansion team record of six straight wins, a record they had previously missed once they dropped their tenth game of the season, and established a new NHL record with eight straight wins.  On February 1, 2018, the Golden Knights set the expansion team record for wins in a debut year with 34 wins after just 50 games, and then on February 21, 2018, set a record for most points with an expansion team in the inaugural season with 84.  Clinching a berth for the 2018 playoffs on March 26, the Golden Knights became the first team since the Edmonton Oilers and Hartford Whalers in the 1979–80 year to make the playoffs in their inaugural season in the league.  On March 31, the Knights clinched the Pacific Division title, becoming the first true expansion team at the four major sports to win its division at its inaugural season (not counting all-expansion divisions, as was the case in the 1967–68 season).  They’d headed the Pacific since December 23, 2017.
On April 11, the franchise won its first playoff game at a 1–0 victory over the Los Angeles Kings in the first game of this set. Six days later on April 17, the franchise made their initial playoff series win against the Kings, winning the fourth game with a 1–0 score, which also became their first playoff series sweep. The Knights became the first team in NHL history to sweep their first playoff series in their first season.  On May 6, 2018, the Golden Knights defeated the San Jose Sharks four-games-to-two, becoming the third team in NHL history to win several playoff series in their inaugural season, and advanced to the Western Conference Finals.  On May 20, Vegas defeated the Winnipeg Jets to win the Western Conference Finals in five games, becoming the third NHL team to advance to the Stanley Cup Finals in its first season, after the Toronto Arenas at 1918 along with the St. Louis Blues in 1968.  The Golden Knights would shed the Stanley Cup Finals to the Washington Capitals in five games. 
In the 2018–19 year, the Golden Knights returned into the playoffs as the third seed of their Pacific Division. They were defeated in the First Round in seven games by the San Jose Sharks, whom the Golden Knights defeated at the Second Round of their prior season.
