The Reading Artillerists was a militia organization founded in Reading, Berks County, Pennsylvania during the late 18th century. Mustering in for the first time during the presidential era of George Washington, members of this artillery unit went on to serve tours of duty in the War of 1812, Mexican–American War and, as members of the Union army of the United States, during the American Civil War, before disbanding. Having determined that Reading needed to improve its military readiness, civic leaders of the 1880s authorized the formation of a new artillery unit, and also chose to name it as "Reading Artillerists" in deference to the original unit's storied history. That militia unit then mustered in for the Spanish–American War, and continued its service during the early part of the 20th
