PROMDI was founded in 1997 by
Lito Osmeña, who served as governor of
Cebu (1988–1992) and chief economic adviser to President
Fidel V. Ramos (1993–1997), and was Ramos' unsuccessful running mate in the
1992 presidential election. A former officer of
Lakas, Osmeña formed PROMDI for his unsuccessful presidential bid in
1998; his running mate was former
South Cotabato governor
Ismael Sueno. In 2001, President
Joseph Estrada was ousted in the
Second EDSA Revolution and Vice President
Gloria Macapagal Arroyo ascended to the presidency. PROMDI joined the pro-Arroyo
People Power Coalition (PPC) alongside Lakas,
Reporma,
Aksyon, the
Liberal Party, and
PDP-Laban. The party won three district seats in the House. However, they were disqualified from the party-list election for failing to meet the criteria of representing the "marginalized and underrepresented" in accordance with the Party-list System Act (R.A. 7941). In
Cebu City, PROMDI's
Tomas Osmeña was elected mayor and
Mike Rama was vice mayor. The
2004 election was dominated by two major coalitions: the pro-Arroyo
K4 and the opposition
KNP. However, PROMDI opted to join Aksyon and Reporma (former Arroyo supporters) to form a third smaller coalition, the
Alyansa ng Pag-asa (Alliance of Hope). They supported the
presidential bid of Aksyon's
Raul Roco. In
2010, Osmeña unsuccessfully ran for a Senate seat. In June 2021, Osmeña announced the revival of PROMDI and their plans to contest the
2022 election at national level. Osmeña died the following month. His son, Mimo, became the new party president. On September 18, PROMDI signed an alliance agreement with the
Pacquiao–Pimentel wing of PDP-Laban and the
People's Champ Movement (PCM), dubbed the MP3 alliance. On September 26, Senator
Manny Pacquiao took his oath as member of PROMDI and was named their honorary chairperson. The party then nominated him as their presidential candidate for
2022. When Pacquiao filed his candidacy on October 1, he declared PROMDI as his party, but asserted that he was not abandoning the leadership dispute of PDP-Laban. Pacquiao's running mate, House Deputy Speaker
Lito Atienza of
Buhay party-list, also filed his candidacy under PROMDI. Abag PROMDI will participate in the
2025 House of Representatives elections as a party-list, with Mimo Osmeña as their first nominee. ==Name and symbols==
