19th Century
A major event in Laguna occurred in 1840, when religious intolerance led the people of Majayjay, Nagcarlan, Bay, and Biñan to join the revolt of Hermano Pule (Apolinario de la Cruz) of Lucban, Tayabas. This revolt was eventually crushed by Governor-General Marcelino de Oraá Lecumberri.
As part of political restructuring during the 19th century, the municipalities of Morong, Pililla, Tanay, Baras, Binangonan, Jalajala, Angono and Cardona were separated from Laguna and re-organized to the province Politico-Militar Distrito de Morong. In 1858, the provincial capital was once again moved from Pagsanjan to Santa Cruz, where it stands until today.
In 1861, José Rizal was born in Calamba to Francisco Mercado and Teodora Alonso. Rizal would become one of the leading members of the Propaganda Movement, who advocated political reforms for the colony. Rizal would go on to write two novels, Noli Me Tangere and El Filibusterismo, which in part fueled additional anti-colonial sentiment, contributing to the eventual Philippine Revolution. In 1896, thousands of inhabitants, especially of Bay, Los Baños, Nagcarlan, Magdalena, Santa Cruz, and Pagsanjan had joined the revolutionary Katipunan. Rizal was executed on December 30, 1896, on charges of rebellion. Today Rizal is recognized as one of the national heroes of the Philippines.
Laguna was one of the eight provinces to rise in revolt against the Spanish misrule led by Generals Paciano Rizal of Calamba, Severino Taiño of Pagsanjan, Agueda Kahabagan of Calauan, and Miguel Malvar of Batangas. One of the early engagements of the revolution was the Battle of Sambat, in Pagsanjan. Katipuneros from Laguna, led by Severino Taiño, took the city of Pagsanjan and attempted to use it as a starting point towards the liberation of the province, but was quelled by forces led by Basilio Augustin.
The defeat in Sambat meant the end of large-scale organized revolt in Laguna, the Malungingnging chapter of the Katipunan failing to replicate the relative success of the revolution in Cavite. The revolutionaries resorted to hit-and-run and guerrilla tactics against the Spanish, lasting until the Pact of Biak-na-Bato on December 14 to 15, 1897. It was only after the execution of Jose Rizal that the revolution flared up again, culminating in the Battle of Calamba in May 1898, and the surrender of the last Spanish garrison in Laguna in Santa Cruz, on August 31 of the same year.
Laguna actively supported the First Philippine Republic proclaimed at Malolos on January 23, 1899. Its two delegates to the Malolos Congress were Don Higino Benítez and Don Graciano Cordero, both natives of Pagsanján.
20th Century
Upon the outbreak of the Philippine–American War, Generals Juan Cailles and Paciano Rizal led the defense of Laguna during the war’s early stages. The Battle of Mabitac was fought in defense of the town of Mabitac and was won by Filipino forces. However, forces led by Henry W. Lawton fought and won in Santa Cruz, Pagsanjan, and Paete, effectively securing the province for American forces. Resistance still occurred during this time. One of the province’s folk hero during the continuing engagements was Teodoro Asedillo, who was considered a bandit by American forces.
By the end of the war, the entire country was occupied by American forces and was taken as a colony. The Taft Commission was established to govern the Philippines during the interim period, which appointed Juan Cailles as the provincial governor of Laguna. Act No. 83, or the Provincial Government Act, established a civilian government under American occupation. During this time, roads were built, schools were established, and in 1917, the Manila Railroad Company extended its line to Laguna as far as Pagsanjan.
During the Japanese occupation of the Philippines (1942–1945), Laguna was a center of Filipino resistance despite the presence of Makapili collaborators.
Beginning in 1945, attacks by the Filipino soldiers of the 4th, 42nd, 43rd, 45th, 46th and 47th Infantry Division of the Philippine Commonwealth Army, 4th Constabulary Regiment of the Philippine Constabulary and the recognized guerrillas against Japanese forces in Laguna increased in anticipation of the Liberation of the Philippines by joint Filipino & American forces.
Economy
Present-day Laguna shows a thriving economy. With a population of 3,035,081 (2015 census), and a total area of 1,760 km2 (680 sq mi) of land, Laguna produces millions of pesos worth of coconuts, rice, sugar, citrus fruits, lanzones and other products. Tourists flock to its beauty spots, especially Pagsanjan Falls, Calamba and Los Baños hot springs, Mount Makiling, Caliraya Lake and many others. Levels of development vary. The towns near Metro Manila have become industrialized whereas the inner towns continue to engage in agricultural production or pursue agri-based industries and cottage and small-scale industries.
Laguna is labeled as the Detroit of the Philippines because of the presence of major vehicle manufacturers in the city of Santa Rosa. It is also considered as the Silicon Valley of the Philippines because of the vast number of electronic and semi-conductor companies operating in the province. Laguna is also the Resort Capital of the Philippines for it houses more than 700 hot spring resorts in the areas of Calamba and Los Baños.
Natural Resources
The main natural resources of Laguna are in its agriculture and fisheries, owing to its position near the Laguna de Bay and the surrounding lowlands.
There are about forty rivers in Laguna with a total area of almost 0.5 km2 (0.19 sq mi). The Laguna de Bay has an approximate area of 3,800 square kilometres (1,500 sq mi) broken down into 2,900 square kilometres (1,100 sq mi) of land and 900 km2 (350 sq mi) of lake proper with 220 kilometres (140 mi) shoreline. The shores of Laguna de Bay provide fishing grounds capable of producing 41,000 metric tons (41,000,000 kg) of fish, or roughly two-thirds of the fresh water fish requirements of Metro Manila.
Laguna has an estimated 300 million US gallons (1,100,000 m³) of underground water. At least seven principal water basins in the province with a total of 5,773 square kilometres (2,229 sq mi) drainage area and 1,316 square kilometres (508 sq mi) level area provide an estimated 9.238 square kilometres (3.567 sq mi) total run-off annually. There are two major watershed reserves in Laguna, the Malabanban Cabunsod Watershed Forest Reserve in San Pablo, and the Caliraya-Lumot River Watershed Forest Reserve, which spans the municipalities of Paete, Cavinti, Kalayaan, and Lumban. Overall, these two watersheds span an area of 11,164.71 ha (27,588.6 acres).
Laguna has a relatively small mining industry compared to the other provinces in the region, with only 11 non-metallic mines registered in the region, and only 8 of which are operating. These mines are found in Santa Cruz, Magdalena, Siniloan, Lumban, and San Pablo. A total of 39.7823 ha (0.397823 km2) are used for mining purposes. Aggregates make up the largest amount in Laguna’s mineral industry, with a value of PHP 16,995,923. Overall, Laguna’s mining economy contributes 8.87% to the region’s total mining economy.
