Cause → Event → Consequence
As insurgent forces under Miguel Hidalgo and Ignacio Allende advanced on Guanajuato, the intendant Juan Antonio Riaño, fearing social unrest, ordered the city's population—including civilian families—to take refuge inside the Alhóndiga de Granaditas, a granary built in 1800 in which Hidalgo himself had previously served as an advisor.
After several hours of fighting on September 28, 1810, Riaño was killed by insurgent fire. The remaining Spanish defenders attempted to surrender, but the royalist military contingent continued resistance. Insurgent forces ultimately breached the granary and massacred both the remaining armed defenders and the numerous civilian families sheltering inside.
The fall of the Alhóndiga shocked royalist New Spain and exposed the brutal character of the early independence conflict. Many historians classify the event less as a battle and more as a massacre of civilians, given the extreme imbalance between the two sides and the killing of non-combatants who had sought refuge there.
