The team remained as the Cleveland Indians for over a century, until the team was renamed the Cleveland Guardians in 2021, after decades of controversy surrounding the "Indians" name. officially becoming the Guardians on November 19, 2021.
The team made its first World Series appearance in 1920 and won the first of their two World Series titles. Since then, the Indians have had three periods of success. The first was from 1947 to 1956, when they had winning records in every season, including a 111–43 record in 1954, which remains the best Major League Baseball regular season record since the 1909 Pirates, and won their only other World Series in 1948. In 1954, they appeared in the World Series, and lost. Cleveland's second highly successful period was from 1994 to 2001, when they had eight consecutive winning seasons, six AL Central division titles, and two World Series appearances in 1995 and 1997, but lost both of these World Series. The third extended period of success began in 2013 under manager Terry Francona, during which they had eight consecutive winning seasons from 2013 to 2020, five playoff appearances, and one World Series appearance in 2016.
Cleveland has also experienced failure in their history. From the split of the American League into two divisions in 1969 until 1993, the Indians did not make a single postseason appearance and played only four winning seasons. They posted 100 losses four times during the era.
