The Kingsland explosion was an incident that took place during World War I at a munitions factory in Lyndhurst, New Jersey, United States, on January 11, 1917. An arbitration commission in 1931 determined that, "In the Kingsland Case the Commission finds upon the evidence that the fire was not caused by any German agent." Germany in 1953, paid $50 million ($510 million in 2022) in reparations to the United States.
