According to historians, the first inhabitants of Kabankalan were people who came from neighboring towns. They derived the name Kabankalan from the word "bangkal" (Nauclea orientalis), a tree that is abundant in the place. The settlers established the Barangay form of government, with which every group has its own leader, called the Capitan.

In 1566 the Christianization of the Island of Negros began with the foundation of the mission of Binalbagan (1575), Tanjay (1580) and Ilog (1584) by the Augustinian missionaries. In 1622, at the request of Bishop Pedro de Arce of Cebu, the Recollects came to evangelize Negros. The spiritual administration of Binalbagan including that of Kabankalan was ceded to them. When the mission of Ilog was turned over to the Jesuits, it had four towns, Ilog being the chief town. The next was Kabankalan which already appears in a document dated 1630 as the center of encomienda of Admiral Cristobal de Lugo y Montalvo. The third was either Jima or Sima. The fourth was probably Su-ay. The Jesuits who served Kabankalan were Fr. Esteban Jayme. After the expulsion of the Jesuits from the Philippines in 1767, the Dominican missionaries came to continue the spiritual administration of Negros with Father Manuel Diez assigned in Kabankalan in 1769. During the Spanish regime, Spaniards taught the people the Spanish language and introduced to them the Roman Catholic religion.

In 1830, the three Capitanes- Polito Moreno, Vicente Rojas and Mariano Vingal-petitioned the government to transfer their barangay located at the Hilabangan River towards the area of Orong and established a town. They elected a migrant from Tigbauan, Iloilo-Leocadio Tayum y Gregorio- their new head, who served for one year. In 1856, 500 commissaries and policeman of Governor Emilio Saravia stationed in the poblacion attacked the stronghold “made of trunk” of the local chief Manyabog at Carol-an who endured the Spanish artillery for a long time. They disbanded only when a stray bullet killed Manyabog. Seeing their leader killed, they set themselves on fire with their houses. The tribal suicide resulted in the deaths 300 of Manyabog's men, while seven died on the opposite side. Prior to the actual revolt in 1898, clandestine activities had already been in the offing, the leaders of the revolution such as Aniceto Lacson joining the Katipunan and others arming themselves. By mid-1896, arms were unloaded in Binicuil, Kabankalan for the hacienderos of Kabankalan, Ilog, Himamaylan, Su-ay and Cauayan but they refrained to join the revolt knowing that they were not prepared and had no confidence in victory. It was not until November 7, 1898, that Kabankalan took up arms after Bacolod was taken over from the Spanish authorities. The Cantonal Republic of Negros was declared on November 5, 1898.

When the Americans came, they introduced a democratic form of government. During this time, a lot of improvements came to the town and new modern techniques of farming were introduced by the Americans to the local farmers that improved their products. On April 2, 1903, the Philippine Commission passed Act No. 716 reducing the 34 municipalities of the Province of Negros Occidental to 21 whereby the municipality of Cavancalan was merged to Ilog. On March 14, 1907, Philippine Commission passed Act. No. 1612 increasing the number of municipalities in Negros Occidental from 21 to 22 by separating from Ilog the former municipality of Cavancalan and reconstituting the same under the name Kabankalan. In mid-1907, a group of rebels called "Pulahanes" led by Papa Isio, raided the town and burned down all the houses. However, the people of Kabankalan quickly recovered and rebuilt the town from the destruction caused by the dissidents. Lorenzo Zayco was elected Municipal President in a special election and took his oath of office, along with other elected officials on January 2, 1908. Pre War-Kabankalan saw the emerging development of the sugar industry. Sugar mills were put up in Hacienda Bearin and Hacienda San Isidro.
