[3] After Agüeybana I (a title akin to High Chief or king) entered in association with the Spanish conquistadors through the guaytiao he became known as Francisco de Aramaná, also being recognized as a Don.

[7] Oral tradition claims that a Spaniard named Juan González somehow survived long enough after being severely injured in the initial Taíno offensive of the Spanish–Taíno War of San Juan–Borikén to reach the region of Toa and warn the conquistadores.

[15] The end of the Napoleonic wars and the elimination of some taxes allowed a new generation of hacendados from the capital of San Juan to benefit from the booming industry, among the mayors Jacinto López Martínez and José Canales.

[16] However, the roads that lead to Western Puerto Rico crossed through el Dorado and this, combined with flooding concerns, did not allow the municipality to develop a proper urban center, with Palo Seco being its main commerce epicenter.

[17] On March 10, 1841, colonial governor Santiago de Méndez Vigo authorized moving all the administrative offices from Dorado to Toa Baja, faced by pressure from the settlers.

[26] After more than a month, the reply contained strong opposition to the separation, heavily criticizing the capacities of those involved in the request citing personal ambitions as a motive and claiming that the lands were unproductive, that the area was plagued with environmental factors that "resulted in the early death" of its residents and that the water was unclean.

[26] The rebuttal also claimed that the barrios pushing for separation were unable too poor to sustain the public workings of a town, despite being the ones that contributed most to the fisco up to this point, the purported lack of personnel and a workforce or that the proximity of the settlements would be unlawful.

[27] After being given copies of Toa Baja's opposition, López and Folgueras requested that the complaints were dismissed and questioned the accuracy of any of the counterarguments, also opting to criticize that some of the proponents were being targeted for being poor, which should not prevent them from entering association.

[28] The group also labelled Toa Baja as a failed municipality by using its iwn criteria, responding that the criticism for lack of a workforce was unfair since despite its age the town faced similar problems.

[31] Méndez Vigo delegated the issue to an aid, Anacleto Buelta, who suggested interviewing the current Toa Baja administration and argued inconsistencies in witness selection.

[35] The Toa Baja Commission, represented by mayor Juan Landrón an overseer and the municipal secretary, proposed that only proprietors, those that paid subsidies, should be consulted, considering the declarations of those that didn't useless and potentially damaging to those that did.

[40] Two days later, López addressed the colonial governor requesting a copy of the aide's conclusion, citing the suspicion that the municipality of Toa Baja had used ineligible witnesses to dilate the process.

[42] After receiving it, aide Melitón Belanzathegui recommended proceeding with the foundation of a new municipality, with Méndez Vigo authorizing the creation of San Antonio del Dorado on November 22, 1842.

[44] The demarcation process was initially overseen by Pedro García with the help of Julio O'Neill of the Bayamón Department with Carlos Vuagneaux taking charge following a suspención due to weather, and began on January 10, 1843, extending for six days.

[47] On March 6, 1843, there was a slave uprising in the hacienda of Francisco Cantero, who after being received by gunfire in the Catholic Church in Toa Baja, fled to the sugar plantations of Dorado, where the government captured them and sentenced several to death.

[48] Despite royal decrees prohibiting the traffic of African slaves, the Spaniards continued illegally importing them, with Dorado mayor José Carreras actively participating in the trade.

[52] By 1848, the municipality of Dorado was running all of its functions under López, now mayor and War Lieutenant and in charge of filling several reports related to the population, wealth and agricultural production.

[55] The industry in question was dominated by López himself, Manuel Skerrett, Francisco Cantero, José Marrero, Carlos Vassallo, Miguel Torrens, Juan P. Nevárez, Florencio Salgado, and the inheritors of María E.

[56] Being located in the Camino Real (Royal Highway) grocery and other types of stores were run by people like Antonio Solé, Benito Carreras, and Juana Sánchez and brothers.

[60] At the First Public Exposition of Industry, Agriculture and Arts, Lechet demonstrated his advances in processing white sugar, which earned him a silver commendation from the Secretary of the Royal Commerce Board, Andrés Viña.

[73] On June 10, 1873, the municipality of Dorado requested permission to widen and deepen the La Plata river mouth to allow larger ships to enter in an attempt to reinvigorate the sugar industry.

[100] Casa del Rey, which after being acquired from the government by López had served as the house of several people and a political center, was restored by the municipality and the ICP during the second half of the 20th Century.

Some local communities have gathered efforts to minimize quarrying and improve land management to protect the remaining karst topography and the fauna and flora that lives in it.

[55] The rock formation known as Ojo de Buey is tourist attraction, also being associated with legends of ghosts and the claim that the pirate captain Roberto Cofresí's treasure is buried near it.

The Dorado page lists Sala de exposiciones del plata Salvador Rivera Cardona, Plaza Conmemorativa 5th Centenario, and Balneario Manuel "Nolo" Morales, as places of interest.

[127] In the early 20th century the Rockefeller family purchased plots of land in the northwest region of the municipality of Dorado where they built a huge private vacation compound.

For example, the Museum Casa del Rey is the house built in most towns controlled by Spain during their colonization, which was intended for the King and Queen to stay if they visited.

[134] Dorado also celebrates fiestas patronales to honor Antonio de Padua, which retain their religious origins but have included cultural activities such as trova contests, the coronation of a queen and La Alborada.

[141] Other festivals and events celebrated in Dorado include: As a historically industrial town, the academic culture is mostly centered around writer José S. Alegría and poet Ferdinand R. Cestero is honored for employing the municipality as part of his pseudonym.

[159] Local athletes include Manolín Maldonado and Angel Maysonet, baseball players Toño Cardona, Nolín Valderrama, Arturito de Jesús, Germán Lanzó, Pedro Díaz, Pito Álvarez, Peoe Carbia, Tomás Palmeras, Mampostial Sánchez, Fabián Cardona and Talí Maldonado and chess player Cucü Alegría, runners Juan Cruz and Millo Lorenzana, and boxers Tony Villa, Carmelo Vázquez and Rafael Santana.
