July 30

On July 10, 1921, Belfast convulsed in some of the worst sectarian violence of the partition era. Over the course of a day and into the nights that followed, gunmen and mobs attacked streets in mixed working‑class districts — the Markets, Short Strand, New Lodge and adjacent shipyard neighborhoods — leaving scores dead or wounded, thousands displaced, and whole terraces blackened by fire. The fighting came at the end of a season of growing hostility tied to partition, job scarcity and the rise of irregular security forces; its effects hardened residential segregation and deepened mistrust of state policing for decades to come.

In a rare and catastrophic aviation incident, a mid-air collision occurred between a commercial airliner and a private jet over Lumut, Malaysia, leaving no survivors and prompting sweeping changes in aviation safety protocols.

On July 14, 2016, a day meant for celebration turned into a nightmare when a terrorist attack struck the heart of Nice, France. Mohamed Lahouaiej-Bouhlel drove a 19-tonne cargo truck into the crowds along the Promenade des Anglais, killing 86 people and injuring 458 others. This tragedy, amidst France’s ongoing state of emergency, left an indelible mark on the nation and the world, underscoring the persistent threat of terrorism.
