The Day of the National Rebellion is observed in Cuba every July 26, commemorating the 1953 attack on the Moncada Barracks, which marked the beginning of the insurrection against Fulgencio Batista's dictatorship. The holiday celebrates the efforts of Fidel Castro and his brother Raúl, who led the attack that ultimately failed but laid the groundwork for the 26th of July Movement and the Cuban Revolution. Festivities typically last for three days, from July 25 to 27, and include various public celebrations. The significance of this day is rooted in the historical context of Batista's rise to power and the subsequent armed struggle against his regime. Despite the initial defeat of the rebels, the attack is remembered as a pivotal moment in Cuba's fight for freedom.
