War of the Worlds

War of the Worlds is a professional wrestling supershow co-produced by the American Ring of Honor (ROH) and Japanese New Japan Pro Wrestling (NJPW) promotions. The two promotions announced a partnership in February 2014, which led to the first War of the Worlds event taking place at the Hammerstein Ballroom in New York City the following May. In 2015, ROH and NJPW presented two War of the Worlds events, both taking place at the 2300 Arena in Philadelphia, Pennsylvania in May. In 2016, War of the Worlds took place over three shows in Dearborn, Michigan, Toronto and New York City.
