Army Day is observed in Guatemala every June 30, commemorating the events of 1871 when the Conservadora administration was overthrown by liberal leaders Miguel Garcia Granados and Justo Rufino Barrios. This coup marked the end of Vicente Cerna's leadership, which had been characterized by constant uprisings. The anniversary was originally known as Revolution Day but was later renamed Army Day (Día del Ejército) to honor the service of the armed forces for national well-being. Celebrations typically include a military parade, primarily organized in Guatemala City, showcasing the country's military and honoring its history. The day recognizes the significant agrarian reforms implemented by Justo Rufino Barrios during his 12-year presidency following the uprising.
