When Minor Sparks Led to Major Consequences

History likes to frame wars as the result of grand ideals, deep conflicts, or inevitable clashes of power. In reality, many wars began because of petty disputes, misunderstandings, wounded pride, or events that spiraled far beyond their original significance. What started as a small insult, a border argument, or a single incident often escalated into years of bloodshed. Looking back, it’s hard not to be surprised by how fragile peace can be. These 20 wars prove that sometimes history turns on moments that feel almost absurd in hindsight.
