Wallpaper and establishment
The NHL has had a presence in Las Vegas since 1991; this year, the town hosted the 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 against the Colorado Avalanche. The NHL awards ceremonies have been 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 again 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 possible home arena, although these rumors were refused by the league.  In November 2014, an unconfirmed report stated that the league had selected 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 vegas expansion group.  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 team, though league commissioner Gary Bettman also warned the media to”[not] create more out of this than it’s”.  The season ticket drive began in February 2015, together with interested parties placing ten percent deposits to its 2016–17 season.  The driveway drew 5,000 residue in its first day and a half, and attained its goal of 10,000 deposits by April 2015. 
In June 2015, the league officially opened the window for prospective owners to bid on expansion teams. With this point, Foley had procured more than 13,200 season-ticket deposits. Two growth programs were submitted: Foley’s program for a Las Vegas team, and a bidding from Quebecor to revive the Quebec Nordiques in a brand new stadium in Quebec City. Both Las Vegas and Quebec were invited to move into Stage II of the league growth bidding in August 2015, and subsequently advanced to Phase III.
In the league owners’ meeting on June 22, 2016, in Las Vegas, the Las Vegas expansion bidding was approved by a unanimous vote, with play to start in the 2017–18 NHL season.  The team became the first major professional sports franchise to be established in Las Vegas, and the very first NHL expansion team since 2000.  Foley dedicated to cover the league’s $500 million expansion fee and began the practice 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 title was revealed 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, 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 into a three-year entry contract. 
Gerard Gallant coaching the Golden Knights during their inaugural 2017–18 season. 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 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, selecting an available player from all 30 teams in the NHL. The draft selections were announced at T-Mobile Arena through the NHL Awards ceremony. Some notable selections included 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 chosen 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 victory. 
The group’s inaugural home game was played on October 10, 2017, hosting the Arizona Coyotes since the second match of a home-and-home series. In the wake of the October 1 mass shooting, the pre-game ceremonies honored the victims of the attack, along with the team issued an appeal for contributions to its charitable arm.  With their 5–2 win, the Golden Knights improved their unbeaten streak to start the season to 3–0, an NHL record for an expansion team.  The Golden Knights are 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 hurt becoming the next Golden Knights’ goaltender to be injured throughout the season after dropping starters Fleury and the recently obtained Malcolm Subban, forcing the team to begin a fourth goaltender in 11 games with Maxime Lagace.  Fifteen games into the season, Vadim Shipachyov became the first player to retire from the NHL as a Golden Knight when he chose to return to the Kontinental Hockey League. Back in December, the Golden Knights set 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 launched a new NHL record with eight consecutive wins.  On February 1, 2018, the Golden Knights set the growth team record for wins in a debut season with 34 wins after just 50 games, and later on February 21, 2018, set a record for most points by 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 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 group at the four main sports to win its division in its inaugural season (not counting all-expansion divisions, as was the case from the 1967–68 year ).  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 match of the set. Six days later on April 17, the franchise earned their initial playoff series win against the Kings, winning the fourth match 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 inaugural season.  On May 6, 2018, the Golden Knights defeated the San Jose Sharks four-games-to-two, getting the third team in NHL history to win multiple playoff series in their inaugural year, also advanced to the Western Conference Finals.  On May 20, Vegas conquered the Winnipeg Jets to win the Western Conference Finals in five games, getting the third NHL team to advance to the Stanley Cup Finals in its first season, following the Toronto Arenas at 1918 and the St. Louis Blues in 1968.  The Golden Knights would lose the Stanley Cup Finals to the Washington Capitals in five matches. 
From the 2018–19 season, the Golden Knights returned to the playoffs since 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 in the Second Round of their previous season.
