Philippines MPBL

Pacquiao formally launched the MPBL on August 29, 2017, with the intent to feature both the commercial and barangay-level side, with teams on the commercial side to have a home locality in addition to a corporate sponsor. The plan was for the league to begin with Luzon-based teams only and then expand to Visayas and Mindanao later on. The expanded league would have two divisions, North and South, where one team from both divisions face in a finals series similar to the format of the National Basketball Association (NBA) in North America. The league was planned to start as early as September 23, 2017 with at least six teams. A preseason tournament was held with the Bulacan Kuyas finishing as champions. Snow Badua was the league's inaugural commissioner, but he did not take on the role when the first season eventually began as six-time PBA champion Kenneth Duremdes succeeded Badua as league commissioner on November 22, 2017.

The MPBL began its inaugural season on January 25, 2018, at the Smart Araneta Coliseum in Quezon City. The inaugural season featured ten teams, all based in Luzon, with the requirement of each team having three homegrown players. In the opening game, the Parañaque Patriots scored a 70–60 victory over the Caloocan Supremos. The playoffs only had eight teams due to the small size, concluding with the Batangas City Athletics winning the inaugural title in the 2018 finals against the Muntinlupa Cagers

In the 2018–19 season, the league added sixteen expansion teams, bringing the total to 26 teams. Five of the sixteen expansions are based in Visayas and Mindanao, thus marking the league's national expansion. The North and South Divisions were introduced and the playoff pool doubled to sixteen teams, eight per division. The league also placed roster restrictions on teams, only allowing one Filipino-foreigner and up to five ex-professional players. This season also saw the inaugural edition of the MPBL All-Star Game, which was held at the SM Mall of Asia Arena in Pasay. The San Juan Knights would win the title that season against the Davao Occidental Tigers in the 2019 national finals, which is to date, the only series to go the full length of five games.

The following 2019–20 season featured 31 teams participating in the league, the most the league had in its history, adding six expansion teams but also saw its first departing team, the Mandaluyong El Tigre. Roster restrictions were also relaxed, allowing more Filipino-foreigners and ex-professional players to play in the league. In December 2019, Chooks-to-Go of Bounty Agro Ventures became the title sponsor of the league under what was initially a five-year deal. This season also saw the debut of the International Invasion series, which saw games being played in the United Arab Emirates and in Canada.

Due to the COVID-19 pandemic in the Philippines, the league suspended play on March 12, 2020. Nearly a year later, on March 6, 2021, the league announced the resumption of its playoffs. The remainder of the league's 2020 playoffs was held at a bubble at the Subic Bay Gymnasium. In a rematch of the 2019 national finals series, the Davao Occidental Tigers won the 2021 national finals against the San Juan Knights.

Because of the restrictions imposed by the government due to the pandemic, the league's 2020–21 season would be cancelled. The league's fourth season would be postponed multiple times before it eventually began in 2022. In October 2021, Chooks-to-Go took over the league's basketball operations.

On November 9, 2021, it was announced that the MPBL would turn into a professional league. A month later, on December 9, 2021, the MPBL was granted professional status by the Games and Amusements Board (GAB). This also allowed the league to feature collegiate players on team rosters, as long as the player itself is a Special Guest Licensee. The league's first professional event was the 2021 Invitational. During which, all roster restrictions were lifted.

The 2022 season would finally begin over a year after last season's conclusion, which featured 22 of the 31 teams from the previous season. The season marked a new sponsorship with sports betting platform OKBet, succeeding Chooks-to-Go as the title sponsor. The Nueva Ecija Rice Vanguards became the first team to achieve a regular season sweep and subsequently won the 2022 national finals against the Zamboanga Family's Brand Sardines. The succeeding 2023 season featured 29 teams, including two expansion teams and five returning teams. The season culminated with the homegrown-laden Pampanga Giant Lanterns sweeping the Bacoor City Strikers in the 2023 national finals.

During this time, a trend began of teams participating in other leagues during the MPBL offseason. This first occurred in FilBasket during the Subic 2021 and Summer 2022 championships, which saw multiple teams participate due to the long gap between the 2019–20 and 2022 seasons. In recent years, teams that were eliminated for the season would compete in the Pilipinas Super League (PSL) during the offseason. It is also around this time where multiple PBA prospects, such as Justine Baltazar, CJ Cansino, and Adrian Nocum, began playing in the MPBL before declaring for the draft.

The 2024 season featured 29 teams, which includes the arrival of two expansion teams but also the departure of three teams. The ex-professional player limit was removed, allowing teams to sign any number of professional players onto their rosters. In April 2024, the league began exploring the possibility of joining the East Asia Super League. However, this was later refuted by EASL CEO Henry Kerins in October that year, stating that "there were no exploratory talks" while also sharing his respect for the league. The season culminated with the first back-to-back championship after Pampanga defeated the Quezon Huskers in three games in the 2024 MPBL finals.

Following the success of the MPBL, Pacquiao has made further developments in grassroots-based sports. On June 15, 2023, the Junior MPBL was unveiled in a press conference. The youth-oriented league's inaugural season began on July 9, 2023, with teams competing in 14-under, 16-under, and 18-under divisions. The junior league will soon feature a 21-under division, billed as the "Junior MPBL D-League", which will commence in May 2024. In the same press conference announcing the junior league, Pacquiao also shared intent to create a volleyball counterpart similar to the MPBL that will cater to female players. That league would be known as the Maharlika Pilipinas Volleyball Association (MPVA) and began on October 22, 2023, with eight teams. On October 27, 2024, it was reported that a direct women's counterpart, the Women's Maharlika Pilipinas Basketball League, will begin its inaugural campaign in January 2025. UST Growling Tigers coach Haydee Ong is set to be the first commissioner of the women's league.

On November 7, 2023, the league launched its social arm, the MPBL Kalinga, with the goal of providing medical assistance to MPBL players, former and current, as well as league officials and staff. In October 2024, a party-list sharing the same acronym, the Maharlikang Pilipino sa Bagong Lipunan party-list, was created in an effort to extend their grassroots program into other sports.
