4th Spanish Armada makes landfall in Ireland at Kinsale.
Spanish forces land at Kinsale, Ireland, in an attempt to support Irish rebels against English rule.
On September 2, 1601, a Spanish fleet known as the Fourth Armada reached Kinsale harbor, aiming to assist the Gaelic lords of Ireland in their rebellion against Elizabethan rule. The expedition marked Spain’s last major effort to challenge English power following the famous Armada of 1588. Spanish soldiers and supplies bolstered the forces of Hugh O’Neill and Hugh O’Donnell, who had sought external aid for their uprising. Despite initial success in landing, the terrain and English defenses led to a protracted siege at Kinsale. The eventual English victory in January 1602 crushed hopes for Irish independence and cemented England’s dominance over Ireland. The episode highlighted the international dimensions of the conflict and the waning reach of Spanish influence.

The destruction erased centuries of urban history and shifted territorial control back to the Papal States. This event underscored the papacy’s capacity for temporal as well as spiritual authority during the Baroque era.

The Kantō Massacre stands as one of the darkest episodes in modern Japanese history, exposing deep-seated xenophobia and breakdowns in law and order. Official estimates of the death toll vary, but scholars agree that the true number of victims may never be fully known.
