Lore & Background

The Celtics' rise to dominance began in the late 1950s, after the team, led by coach Red Auerbach, acquired Bill Russell in 1956, later becoming the cornerstone of the Celtics dynasty. Led by Russell, Bob Cousy, and Tom Heinsohn, the Celtics won their first NBA championship in 1957. Russell, along with a talented supporting cast of future Hall of Famers including Heinsohn, K. C. Jones, John Havlicek, Sam Jones, Satch Sanders, and Bill Sharman (who was part of the 1959 and 1960 title teams before leaving after the 1960-61 season), would usher the Celtics into the greatest period in franchise history, winning eight consecutive NBA championships from 1959 to 1966.

(Don Nelson, often associated with the dynasty, joined the team later and was part of the last two title runs in 1965 and 1966.) After Russell became the team's player-coach, as well as the first African American head coach in a major U.S. professional sports league, they won back-to-back titles in 1968 and 1969. The Celtics entered a period of rebuilding after Russell retired in 1969.

In the mid-1970s, the Celtics became contenders once again, winning championships in 1974 and 1976 under the leadership of head coach Tom Heinsohn with Dave Cowens, Havlicek, and Jo Jo White. In the 1980s, the Celtics returned to dominance. Anchored by the 'Big Three' of Larry Bird, Kevin McHale, and Robert Parish, the team experienced a renewed rivalry with the 'Showtime' Lakers and won championships in 1981, 1984, and 1986, the latter two with head coach K. C. Jones.

After the retirements of Bird and McHale, the departure of Parish, and the untimely deaths of 1986 draft pick Len Bias and star player Reggie Lewis, the Celtics struggled through the 1990s and much of the early 2000s. After another period of rebuilding, the Celtics assembled a new 'Big Three' around team captain Paul Pierce by acquiring Ray Allen and Kevin Garnett in the 2007 off-season. Under the leadership of head coach Doc Rivers, the team defeated the Lakers to win their 17th championship in 2008, while also losing to the Lakers in the 2010 Finals.

Allen, Garnett, and Pierce were no longer with the team by the start of the 2013–14 season, with Garnett and Pierce being traded to the Brooklyn Nets for four total future first round picks. With two of these first round picks, the team drafted Jaylen Brown and Jayson Tatum in 2016 and 2017, respectively. Led by 'The Jays', the team returned to the NBA Finals in 2022, losing to the Golden State Warriors, and defeated the Dallas Mavericks in 2024 to secure their 18th championship.
