The Raiders officially moved to Las Vegas and became the Las Vegas Raiders in the 2020 NFL season. The move was approved by NFL owners on March 27, 2017, after which construction began on their new stadium, Allegiant Stadium. The team played their last seasons in Oakland in 2017 through 2019 before relocating to Las Vegas in January 2020. The inaugural season at the new stadium was impacted by the COVID-19 pandemic, leading to games without fans in attendance initially.
