The Cleveland Indians are a professional baseball team based in Cleveland, Ohio. Since their establishment as a Major League franchise in 1901, the Indians have won two World Series championships, in 1920 and 1948. The "Indians" name originates from a request by the club owner to decide on a new name, following the 1914 season. In reference to the Boston Braves (now the Atlanta Braves), the media chose "the Indians". Their mascot is called Slider. The Cleveland team originated in 1900 as the Lake Shores, when the American League (AL) was officially a minor league. One of the AL's eight charter franchises, the major league incarnation of the club was founded in Cleveland in 1901.
