With the war over, he continued his law studies while working as the driver of the company bus of Elizalde & Co. From 1947 to 1957, he climbed the corporate ladder to become the company's Public Relations and Personnel Manager, and during the same period, passed the
bar examinations and became a lawyer. He was also a bank safe and home safety box salesman. Bagatsing first entered public service in the 1957 elections when his province mate, then-presidential candidate and former
Speaker of the House of Representatives of the Philippines José Yulo, convinced him to run for Congress in Manila's then third district of
Sampaloc,
Santa Mesa (then part of Sampaloc), and
San Miguel. He was elected Congressman for the first time and became chairman of the
House Veterans Committee. He was re-elected in 1961 and held the chairmanship of the powerful Justice Committee. As a legislator, Bagatsing authored several laws, such as the Philippine Veterans Act, the National Stud Farm Law, the laws creating the
Bureau of Immigration, the
Integrated Bar of the Philippines, the
National Defense College of the Philippines and the
Eulogio "Amang" Rodríguez Institute of Science and Technology, among others. After his second term, he joined the Cabinet, becoming the country's chief graft-buster as Head of the Presidential Agency on Reforms and Government Operations (PARGO) from 1967 to 1969. During his stint at PARGO, Bagatsing was dubbed by the
Philippine Free Press as "The Incorruptible" for his prosecution of several high-profile corruption cases against prominent and high-ranking officials, including the conviction and expulsion of a city mayor for graft. In 1969, he ran again for his old congressional seat in Manila and was overwhelmingly elected to a third term. During his ten years, or three terms, in the
Philippine House of Representatives, Bagatsing was consistently awarded and included in the lists of the country's "Ten Most Outstanding Congressmen" and "The 10 Most Useful Legislators of the Republic". He was a leading reformer and a relentless crusader against the spread of
communism in the
Asia-Pacific region of the world as the founding chairman of the Philippine Anti-Communist League.
Plaza Miranda bombing; Mayor of Manila Bagatsing was one of the survivors of the
Plaza Miranda bombing on August 21, 1971, which was at that time considered one of the bloodiest political massacres in Philippine history. Nine were killed and almost a hundred more—including Bagatsing—were wounded after two grenades were thrown on the stage by still-unknown assailants. The public rally was meant to be Bagatsing's official proclamation as mayoral candidate for Manila of the opposition
Liberal Party. He was among the three most critically injured, along with Senators
Jovito Salonga and
Sergio Osmeña, Jr., who nearly lost their lives as they were front and center on the elevated platform, which was the epicenter of the bomb blast. Others who were also hurt included prominent Philippine politicians such as
Gerardo Roxas,
Eva Estrada-Kalaw,
Genaro Magsaysay,
Ramon Mitra,
Eddie Ilarde,
Salipada Pendatun, Roberto Oca Jr. and
John Osmeña. Bagatsing was briefly
clinically dead until he was revived by emergency medical staff in the hospital, being confined for almost three months while undergoing numerous delicate operations. Shrapnel fragments damaged Bagatsing's lower abdomen, right arm, and right cheek bone, and Bagatsing's leg was amputated, badly damaging also his abdomen, right cheek bone and right arm. His wife, Juanita, was also hurt in the blast, with shrapnel embedding her stomach, thighs, and hands. This became a rallying point that galvanized support for their party and their electoral campaign. In the 1971 local elections, Bagatsing defeated incumbent Mayor
Antonio Villegas for the mayoralty of the City of Manila. Early in his fifteen-year term, he established the first
Barangay Bureau in the Philippines, creating the blueprint for the
barangay (village) system as the basic socio-political unit for Manila. This was quickly replicated by the national government and still survives to this day. He also set up the Manila Youth Bureau and the Tourism Office of Manila, which was a first for any local government. Bagatsing then spearheaded the awarding of land titles to many of the city's indigent landless families, further endearing him to the poor, who were all grateful and glad to have the achievement of finally owning the land of their homes. He also established several multi-sectoral cooperatives especially benefiting the vendors in the city's public markets, providing vital financial assistance and livelihood opportunities for Manila's less fortunate citizens. Many schools, educational institutions, hospitals, health centers, public markets, daycare centers, roads and public parks were built and developed in his incumbency, among them, the Ospital ng Sampaloc, the College of Medicine Building of PLM or the
Pamantasan ng Lungsod ng Maynila, the Plaza Noli, the Rajah Sulayman Plaza, the bigger Manila Public Library, the Dapitan Sports Complex, Tondo High School and other public schools. Bagatsing, an early environmentalist, embarked on a massive citywide tree planting program, personally planting, even watering, most of the trees in and around the
Manila City Hall and across the entire stretch of España Boulevard, as well as, the coconut trees on the famous bay-walk of
Roxas Boulevard along
Manila Bay. Before the life-threatening injuries he sustained in the
Plaza Miranda tragedy, Bagatsing was an avid sportsman and created the Manila Sports Council, the city's grassroots sports development office. The
Anak ng Maynilà (Child of Manila) Youth Leadership Training Program, which was a self-help seminar and spiritual improvement retreat, regularly held in the nearby rural, coastal and mountain areas of
Cavite,
Batangas and Alabang, was also implemented by Bagatsing, as the multitudes of Manila's young, the children and students, especially the disadvantaged, would always look forward, with eager anticipation and excitement, to be part of this worthwhile endeavor. Bagatsing also made sure to take good care of the welfare of the city's workers and public school teachers by increasing their salaries, wages and benefits. It was also in 1973 when Bagatsing established the Manila Barangay Bureau which recognized and institutionalized the barangay (village) as the basic political unit, this was an administrative first in local governance which enabled basic services to be delivered at the grassroots level. The establishment of the "barangay" was so innovative that then President Marcos adopted it and rolled it out nationwide. This achievement is immortalized and recognized in the historical marker under Bagatsing's portrait at the Manila City hall. The City of Manila was at the height of its stature during most of Bagatsing's leadership as
Makati and
Quezon City were still largely undeveloped. It was during this time that Manila, once again, became the capital city of the Philippines, through an executive order by then President
Ferdinand Marcos, and evolved to be the center of the country's cultural scene with the advent of the so-called disco-craze and the popular
Manila Sound, while classic films from the period such as
Manila in the Claws of Light and
Manila by Night highlighted the economic inequality present in the city. It was also during this period that Manila gained further prominence in the international spectrum, becoming the first city in
Asia to host the
Miss Universe 1974 pageant that saw
Spanish beauty
Amparo Muñoz win the title, crowned by Filipina
Margarita Moran,
Miss Universe 1973. Just days prior to the main event, in order to emphasize and promote the core essence of the
Miss Universe movement's advocacy, cause, and purpose, Bagatsing had organised a local festival featuring a splendid procession of select pageant candidates parading around and throughout Manila's inner-streets, communities, and
barangays, with the aim of bringing closer together the foreign international beauties and the city's common folk. A pioneer, Bagatsing was among the first City Mayors to establish a Manila Tourism bureau. The following year, adding to its global acclaim, the city's name became renowned in the sporting world due to the
Thrilla in Manila between
Muhammad Ali and
Joe Frazier. The legendary match was actually held at the
Araneta Coliseum in
Quezon City, but the promoters decided to highlight the City of Manila, with Ali enjoying his stay at the historic
Manila Hotel, often jogging around the boulevards of Manila, mingling and interacting with the locals. Because of this, Bagatsing gladly provided Ali with a rather large security detail and even accompanied the American boxer to some of his training sessions. In December 1979, Manila Avenue in Jersey City,
New Jersey, the first main thoroughfare in the
United States named after the Philippine capital, is inaugurated by Bagatsing together with members of the Jersey City Council before an elated Filipino-American community. Due to their collective effort, the former Grove Boulevard had been rechristened Manila Avenue upon adoption of local Jersey City Ordinance S-326, which further cemented the partnership among the two major cities and was considered a milestone in global intercity relations and diplomacy. Immediately after advancing Manila's presence in the East Atlantic Seaboard, Bagatsing then focused towards the Pacific side, strengthening its close ties with the City and Borough of
San Francisco, overseeing many mutual economic and cultural exchanges involving the two key bay cities, including high-profile back-to-back official missions and "sister-city summits" between then-San Francisco Mayor, now
U.S. Senator,
Dianne Feinstein and Mayor Bagatsing who visited each other's city, of which emanated a friendship that remained even following their respective mayoral incumbencies. Bagatsing, a Liberal Party stalwart, was able to keep his post during the entire martial law years by maintaining his clean public service record. He was also one of the first officials to voluntarily step down to allow for a leadership transition after the
1986 People Power Revolution. In 1992, he tried to run for Mayor again under
Laban ng Demokratikong Pilipino but placed third losing to
Alfredo Lim by a margin of 89,503. ==Charity and civic work==
