The team originated in 1901 as the Philadelphia Athletics (the term "Athletic" referred to athletic "gentlemen's clubs" of the late 1800's and early 1900's; in those days the term referred to clubs organized for amateur athletic competition, as opposed to the modern use of the term as a euphemism for places featuring nudity). The team relocated to Kansas City, Missouri in 1955 and again to Oakland in 1968.
The team itself has been among the more successful of American League franchises (it has won nine World Series and 15 American League pennants, though during its Kansas City tenure it won none of either); however, it has been plagued by poor attendance and financial woes (due in part to being located in the same metropolitan area as the more-established San Francisco Giants and by being located in Oakland as opposed to the Giants being located in wealthier San Francisco).
The team plays in Oakland-Alameda County Coliseum (which has had several name changes for naming rights, but as of 2017 reverted to its original name). Until the end of the 2019 season it shared the stadium with the National Football League's Oakland Raiders, the last such arrangement (the Raiders relocated to Las Vegas). Because of this, the stadium's baseball layout gives it far and away the largest amount of foul territory in MLB; balls that would go into the stands elsewhere end up routinely being caught for outs.
