As a charter member of the American Football League (AFL) in 1960, they won one AFL championship in 1967 and appeared in Super Bowl II, losing to the Green Bay Packers by a score of 33-14. The team joined the NFL in 1970 as part of the AFL–NFL merger. Since joining the NFL, the Raiders have won three Super Bowls (XI, XV, XVIII). The Raiders relocated to Los Angeles from 1982-1994, then moved back to Oakland in 1995. The Raiders plan to relocate to Las Vegas by 2020 after the NFL approved the move of the franchise.
After the Raiders lost to the Green Bay Packers in Super Bowl II, the Raiders avenged the loss by winning the first five regular season contests between the teams in head-to-head contests from 1972 through 1987. Since then, the Packers have won all six regular season games, taking the overall head-to-head series, 7-5.
Among additional memorable moments, the Lambeau Leap was first introduced when Reggie White picked up a loose fumble and lateralled the ball to LeRoy Butler, who ran for touchdown score and jumped into the stands in a 1993 meeting that spawned the "Lambeau Leap". In 2003, one day after his father's passing, Brett Favre played a career game against Oakland by passing for 399 yards and four touchdown passes.
A few months after the first AFL draft in 1959, the owners of the yet-unnamed Minneapolis franchise accepted an offer to join the established National Football League (NFL) as an expansion team (now the Minnesota Vikings) in 1961, sending the AFL scrambling for a replacement. At the time, Oakland seemed an unlikely venue for a professional football team. The city had not asked for a team, there was no ownership group and there was no stadium in Oakland suitable for pro football and there was already a successful NFL franchise in the Bay Area in the San Francisco 49ers. However, the AFL owners selected Oakland after Los Angeles Chargers owner Barron Hilton threatened to forfeit his franchise unless a second team was placed on the West Coast. Accordingly, the city of Oakland was awarded the eighth AFL franchise on January 30, 1960, and the team inherited the Minneapolis club's draft picks.
Upon receiving the franchise, Oakland civic leaders found a number of businesspeople willing to invest in the new team. A "name the team" contest was held by the Oakland Tribune, and the winner was the Oakland Señors. After a few weeks of being the butt of local jokes (and accusations that the contest was fixed, as managing general partner Chet Soda was fairly well-known within the Oakland business community for calling his acquaintances "señor", the franchise (and its owners) changed the team's name nine days later to the Oakland Raiders, which had finished third in the naming contest. The now-familiar team emblem of a pirate (or "raider") wearing a football helmet was created, reportedly a rendition of actor Randolph Scott.
