September 23, 1868: Grito de Lares

A group of patriots of Puerto Rico fought for the liberation of the island from the Spanish government, but they were defeated.

In America we call "grito" that first moment of battle for independence.

Other cries for independence:

July 4, 1776 = USA Declaration of Independence

September 16, 1810 = Grito de Dolores, México

October 10, 1868 = Grito de Yara, Cuba
