Background and Institution
The NHL has had a presence in Las Vegas since 1991; this year, the town hosted the first outdoor game involving two NHL teams — a preseason exhibition between the Los Angeles Kings and New York Rangers outside Caesars Palace. The Kings would subsequently arrange”Frozen Fury” — a series of annual preseason matches in Las Vegas against the Colorado Avalanche. The NHL awards ceremonies have been held in Las Vegas because 2009.  In 2009, the press speculated about a strategy involving Hollywood producer Jerry Bruckheimer to move the Phoenix Coyotes into Nevada. 
Rumors of a vegas expansion group surfaced in August 2014, pointing to a brand new indoor stadium on the Strip (built as a joint venture between Anschutz Entertainment Group, owners of the Los Angeles Kings, and MGM Resorts International) as the potential home arena, even though 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 this National Basketball Association’s Sacramento Kings, and founders of the Palms Casino Resort) to lead the ownership group to get a Las Vegas expansion team.  In December 2014, the NHL’s board of governors decided to permit Foley to maintain a season ticket push to judge interest in a Las Vegas group, though league commissioner Gary Bettman also warned the press to”[not] create more out of this than it is”.  The season ticket drive started in February 2015, together with interested parties putting ten percent deposits for its 2016–17 season.  The drive brought 5,000 deposits in its 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 stage, Foley had secured over 13,200 season-ticket deposits. Two growth applications were filed: Foley’s application for a Las Vegas team, and a bid from Quebecor to revive the Quebec Nordiques at a new stadium in Quebec City. Both Las Vegas and Quebec were encouraged to move into Phase II of this league expansion bid in August 2015, and then advanced to Phase III.
In the league owners’ meeting on June 22, 2016, in Las Vegas, the Las Vegas expansion bidding was accepted with a unanimous vote, with play to begin at the 2017–18 NHL season.  The group became the first major professional sports franchise to be based in Las Vegas, and also the first NHL expansion team since 2000.  Foley committed to pay the league’s $500 million expansion fee and began the practice of hiring the team’s principal personnel and ascertaining its official identity. Foley declared that former Washington Capitals general manager George McPhee are the franchise’s first general manager.  On November 22, 2016, the title was shown as the Vegas Golden Knights.
Start of operations: 2017–present About March 1, 2017 (coinciding with the league’s trade deadline), the team finished its expansion fee payments and filings, which makes it eligible to officially begin operations such as free agent acquisition, and involvement in league meetings.  Five days later, the Golden Knights made their first employees move by registering Reid Duke into a three-year entry contract. 
Gerard Gallant coaching the Golden Knights during their inaugural 2017–18 year old. Gallant was named as the head coach in April 2017.
The group announced inaugural head coach Gerard Gallant on April 13, 2017.  Over the next two weeks, the Golden Knights developed their farm system, announcing affiliations with the Chicago Wolves of the American Hockey League and the Quad City Mallards of the ECHL. 
The group participated 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 declared at T-Mobile Arena during the NHL Awards ceremony. Some noteworthy selections contained goalie Marc-Andre Fleury in the Pittsburgh Penguins and winger James Neal in the Nashville Predators. At the 2017 NHL Entry Draft, Cody Glass was the first player selected by the Golden Knights. The Golden Knights played their first match on October 6 against the Dallas Stars with Neal scoring the franchise’s first two goals en route to their first success. 
The team’s inaugural home game was played on October 10, 2017, hosting the Arizona Coyotes as the second game of a home-and-home series. In the wake of the October 1 mass shooting, the pre-game ceremonies honored the victims of this assault, and the group issued an appeal for donations to its charitable arm.  With their 52 triumph, the Golden Knights increased 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 started their inaugural season winning eight of their first nine matches. During their tenth game, goaltender Oscar Dansk was hurt getting the next Golden Knights’ goaltender to be injured throughout the season after losing starters Fleury along with the newly acquired Malcolm Subban, forcing the team to start a fourth goaltender in 11 games with Maxime Lagace.  Fifteen games into the season, Vadim Shipachyov became the first participant to retire from the NHL as a Golden Knight when he chose to go back to the Kontinental Hockey League. In December, the Golden Knights set another NHL expansion team record of six consecutive wins, a record they had previously missed when they dropped their tenth match of the season, and established a new NHL record with eight straight wins.  On February 1, 2018, the Golden Knights place the growth team record for wins in a debut season with 34 wins after only 50 games, and later on February 21, 2018, specify a record for most points with an expansion team in the inaugural season with 84.  Clinching a berth for its 2018 playoffs on March 26, the Golden Knights became the first team as 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 group at the four main sports to win its division in its inaugural season (not counting all-expansion branches, as was the situation from the 1967–68 season).  They had 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 series. Six days later on April 17, the franchise earned their initial playoff series win against the Kings, winning the fourth match by 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 first season, and advanced to the Western Conference Finals.  On May 20, Vegas defeated the Winnipeg Jets to win the Western Conference Finals in five matches, becoming the third NHL team to advance to the Stanley Cup Finals in its first season, after the Toronto Arenas in 1918 and the St. Louis Blues in 1968.  The Golden Knights would lose the Stanley Cup Finals to the Washington Capitals in five matches.
