El Grito de Lares (The Cry of Lares) —also referred as the Lares uprising, the Lares revolt, Lares rebellion or even Lares Revolution - refers to the revolt against Spanish rule in Puerto Rico which occurred on September 23, 1868, in the town of Lares, Puerto Rico.

Seeds for revolt

Rebellion occurs
The Lares uprising, commonly known as the "Grito de Lares" occurred on September 23, 1868, but was planned well before that date by a group led by Dr. Ramón Emeterio Betances and Segundo Ruiz Belvis, who on January 6, 1868 founded the "Comité Revolucionario de Puerto Rico" (Revolutionary Committee of Puerto Rico) from their exile in the Dominican Republic. Betances authored several "Proclamas" or statements attacking the exploitation of the Puerto Ricans by the Spanish colonial system and called for immediate insurrection. These statements soon circulated throughout the island as local dissident groups began to organize.
That same year, poetess Lola Rodríguez de Tió inspired by Ramon Emeterio Betances's quest for Puerto Rico's independence, wrote the patriotic lyrics to the existing tune of La Borinqueña.
Secret cells of the Revolutionary Committee were established in Puerto Rico by Mathias Brugman, Mariana Bracetti and Manuel Rojas bringing together members from all sectors of society, to include landowners, merchants, professionals, peasants, and slaves. Most were "criollos" (born on the island). The critical state of the economy, along with the increasing repression imposed by the Spanish, served as catalysts for the rebellion. The stronghold of the movement were towns located on the mountains of the west of the island.
Although original plans called for the insurrection to begin in Camuy on September 29, Spanish authorities on the island discovered the plan forcing the rebels to move up the date. On the night of September 19 a Spanish captain stationed in Quebradillas, Juan Castañón, overheard two cell members commenting on the plans: on September 29 the troop at Camuy would be neutralized by poisoning the bread rations. Given the fact that September 29 would be a holiday for most laborers, simultaneous uprisings would occur, beginning with the cell in Camuy, and following with the ones in various other points; reinforcements would come in through a ship, "El Telégrafo", and the cells would be reinforced by more than 3,000 mercenaries. Castañón alerted his commanding officer in Arecibo, and the cell leaders at the Lanzador del Norte cell in Camuy were soon arrested.

Planning stage
It was then agreed to first strike at the town of Lares on September 24. Some 400–600 rebels (Spanish journalist José Perez Morís puts the number closer to 1000) gathered on that day in the hacienda of Manuel Rojas, located in the vicinity of Pezuela, on the outskirts of Lares. Poorly trained and armed, the rebels reached the town by horse and foot around midnight. They looted local stores and offices owned by "peninsulares" (Spanish-born men) and took over the city hall. Spanish merchants and local government authorities, considered by the rebels to be enemies of the fatherland, were taken as prisoners. The revolutionaries then entered the town's church and placed the revolutionary flag knitted by Bracetti on the High Altar as a sign that the revolution had began and the Republic of Puerto Rico was proclaimed at (2:00 AM local time) under the presidency of Francisco Ramirez Medina. All slaves who had joined the movement were declared free citizens.

Confrontation at San Sebastián
Some 475 rebels were imprisoned, among them Manuel Rojas and Juan Rius Rivera who was later to become the Commander-in-Chief of the Cuban Liberation Army of the west after Gen. Antonio Maceo's death.
On November 17, a military court imposed the death penalty, for treason and sedition, on all prisoners. Nevertheless, in an effort to appease the already tense atmosphere on the island, the incoming governor, José Laureano Sanz, dictated a general amnesty early in 1869 and all prisoners were released.

Aftermath
Commemorating the Grito de Lares as a holiday was outlawed by both Spanish and American authorities in Puerto Rico, during different time periods. The Spanish prohibition lasted until its colonial rule over Puerto Rico formally ended in 1899. Consequently, besides minor yearly events by the people of Lares celebrated afterwards, the Grito was almost forgotten by most people. However, pro-independence supporters such as José de Diego and Luis Lloréns Torres intended to popularize the idea of commemorating the event as a holiday. De Diego, for instance, requested the foundation of the University of Puerto Rico at Mayagüez (which he proposed to the Puerto Rican Legislative Assembly) to occur on 23 September 1911, as to coincide with the Grito.
In the late 1920s members of the Nationalist Party of Puerto Rico staged minor celebrations in the town of Lares as both historical and fund-raising efforts. When Pedro Albizu Campos gained control over the party "frivolous" activities related to the Grito (such as the yearly fundraising dance) were terminated, and a series of rituals developed to commemorate the event in a dignified manner. One of Albizu's better known quotes is: "Lares es Tierra Santa, y como tal, debe entrarse a ella de rodillas" ("Lares is Holy Land, and as such, it must be visited kneeling down").
Key to the rituals associated with the Grito is the gift, given by Chilean writer Gabriela Mistral to Albizu's family, of a tamarind tree obtained from Simón Bolivar's estate in Venezuela. The tree was planted at the Plaza de la Revolución with soil taken from the eighteen other Spanish-speaking Latin American countries. Albizu meant to give the Plaza a living symbol of solidarity with the struggle for freedom and independence initiated by Bolivar (who, while visiting Vieques, promised to assist the Puerto Rico independence movement, but whose promise never materialized due to the power struggles surrounding him), as well as a symbol of the bittersweet (as the trees' fruit) hardships needed to reach Puerto Rico's independence. As such, the Tamarindo de Don Pedro was meant to resemble the Gernikako Arbola in the Basque Country between Spain and France.
In 1969, under the administration of Governor Luis A. Ferré, a statehood supporter and political posturer, Lares was declared a Historic Site by the Institute of Puerto Rican Culture, and is known as the birthplace of Puerto Rican Nationalism. The Grito is not a national holiday in Puerto Rico[1], although it is considered as such by the University of Puerto Rico (see above).
