In 1897, Antonio Mattei Lluberas visited the Puerto Rican Revolutionary Committee in New York City.
There he met with Emiterio Betances, de Mata Terreforte and Méndez Martinez; together they planned a major coup.
Betances was to direct it, Mendez Mercado would organize it, and General Rius Rivera would command the armed forces.
At the time Ríus Rivera, who had joined the Cuban Liberation Army and José Martí's struggle for Cuban independence, was the Commander-in-Chief of the Cuban Liberation Army of the West.

Mattei Lluberas purchased 30,000 machetes, which were to be distributed amongst the rebels.
He returned to Puerto Rico with a Puerto Rican flag and began to proceed with the rebellion plans.

The Spanish authorities found out about their plans.
Mattei Lluberas demanded that the insurrection start immediately rather than in December.
The other leaders feared that such a haste action would lead to the same disastrous results as had El Grito de Lares.

Mattei Lluberas and the Puerto Rican Commission in New York had been trying to convince President William McKinley to invade Puerto Rico for some time.
After the US took control of Cuba, McKinley approved the invasion of Puerto Rico.
A convoy of ships left Tampa, Florida and on July 21 another convoy departed from Guantánamo for a 4-day journey to Puerto Rico.

Under the terms of the Treaty of Paris of 1898, ratified on December 10, 1898, the United States annexed Puerto Rico.
