The name of the city comes from a legend that during the early time of the Spanish period in the country, two "guardias civil" or soldiers were lost and passing through what is now Calamba. The soldiers met a young lady who came from a river carrying a jar of water and a wooden stove. The soldiers unwittingly in Spanish language and in authoritative tone, to conceal the fact that they were lost, asked the local maiden the name of the place they were in. The lady, who speaks only her native language, naturally thought she was being interrogated about what she was carrying and nervously uttered "kalan-banga", meaning "clay stove" (kalan) and "water jar" (banga). Because the Spaniards could not pronounce it properly, the town has been called Calamba supposedly since then. This legend is immortalized with a large concrete water jar erected in the city plaza with the names of the city's barangays written on its surface. It is considered the "World's Biggest Claypot". This same jar is also found in the city's seal. The plaza was proposed by Dr. Agapito Alzona, then the town councilor to utilize the waste area where the old town market relocated from. The resolution was approved by the then town mayor Roman Lazaro and added additional P5,000 for the fence to the original P15,000 construction cost. It was completed in 1939.
The oldest part of Calamba is believed to be Barangay Sucol where its first settlers remained. With the arrival of Spaniards, the whole area was converted into a hacienda, then a part of Tabuco (now known as Cabuyao City). Calamba became an independent pueblo on August 28, 1742, and formed into the town of Calamba in 1770. In 1813, Calamba was placed in the hands of “encargados” by the Dominican Brothers, who divided into portions and sold the haciendas to the natives during the American regime.
During the Japanese occupation in World War II, the city was the theater of a massacre during which the Imperial Japanese Army killed at least 2,000 civilians. The St. John the Baptist Church, established in 1859, was burned by the Japanese during World War II. It was reconstructed by Fr. Eliseo Dimaculangan. It was the christening site of José Rizal. The original baptismal font has been preserved and refurbished.
After a process of more than seven years, Calamba became the second component city of the Laguna by virtue of Republic Act No. 9024, “An Act Converting the Municipality of Calamba, Province of Laguna into a Component City to be known as the City of Calamba.” R.A. 9024 was signed into law by President Gloria Macapagal-Arroyo on March 5, 2001, at the Malacañan Palace. The Commission on Elections (COMELEC) then set the plebiscite for Calamba’s cityhood on April 21, 2001 where 15,056 residents participated. 3,413 or 22.67% voted “No” while the remaining 77.33% voted “Yes” to Calamba’s conversion into a component city.
As early as 1994, the town’s Sangguniang Bayan approved Resolution No. 60, Series of 1994 requesting the Senate of the Philippines thru its president and the House of the Representatives thru its speaker to co-sponsor a bill for Calamba’s conversion into a city. It was only after two years that another resolution, Resolution No. 115 was passed requesting then Honorable Congressman Joaquin M. Chipeco Jr, to co-sponsor a bill for Calamba’s cityhood and requesting the Sangguniang Panlalawigan for their comments and recommendations regarding the matter. Another two years passed before House Bill No. 986 and Senate bill Nos. 1630 and 1791 were filed in the House of Representatives by Congressman Chipeco and Senate of the Philippines by Senators Franklin M. Drilon and Sergio Osmeña, III, respectively.
It was only in the year 2000 that the motion for Calamba’s cityhood was fast tracked. Then Mayor Severino J. Lajara requested favorable endorsement of House Bill No. 986 from the Sangguniang Panlalawigan on January 3, 2000. The Sangguniang Bayan also endorsed House Bill No. 986 and Senate Bill Nos. 1630 and 1791 and also requested favorable endorsement from the Sangguniang Panlalawigan on the same month. A month passed and Mayor Lajara sent a follow-up letter to then Vice-Governor Teresita “Ningning” Lazaro on updates regarding the matter.
On March 8, the House Committee on Local Government approved House Bill No. 986 on 2nd reading at a hearing held at Hotel Rembrandt, Quezon City. The same House Committee conducted a public hearing on House Bill No. 986 at the Calamba Elementary School (Central II) gymnasium on March 23, approving the House Bill in principle. House Bill 986 was deliberated in April by the House of Representatives in plenary session and approved as House Bill No. 10661, which was then filed with the Senate of the Philippines in June.
The year 2001 came and brought about approval on 2nd reading of Senate Bill Nos. 1630 and 1791 and House Bill No. 10661 in a hearing held on February 5 at the Ambrocio Padilla Hall, Senate of the Philippines. Three days later, February 8, Senate Bill Nos. 1630 and 1791 and House Bill No. 10661 was deliberated in Plenary Session and was approved as Republic Act No. 9024.
