the Bucks played their first NBA regular-season game against the Chicago Bulls before a Milwaukee Arena crowd of 8,467. As is typical with expansion teams, the Bucks' first season (1968–69) was a struggle. Their first victory came in their sixth game as the Bucks beat the Detroit Pistons 134–118; they won only 26 more games in their first year. That year, the Bucks' record earned them a coin flip against their expansion cousins, the Phoenix Suns, to see who would get the first pick in the upcoming draft. It was considered a foregone conclusion that the first pick in the draft would be Lew Alcindor of UCLA.

Subsequently, the Bucks, now in the Western Conference, finished 66–16, the second-most wins in NBA history at the time, and still a franchise record. During the regular season, the Bucks recorded a then-NBA record 20-game win streak. Posting a 12–2 record in the playoffs, they won their first NBA championship on April 30, 1971, by sweeping the Baltimore Bullets in four games. By winning the championship in only their third season, the Bucks became one of the fastest true expansion teams in North American professional sports history to win a league championship. The Bucks remained a powerhouse for the first half of the 1970s. In 1972, Alcindor, who had already privately converted to Islam and changed his name, publicly announced his name change to Kareem Abdul-Jabbar. The Bucks reached the division/conference finals for the third year in a row, but lost
