Dignitaries gather on a garland-draped reviewing stand for a formal flag ceremony bearing the emblem of Nicaragua's Guardia Nacional, the national constabulary organized under U.S. Marine Corps training and oversight in the late 1920s. Ceremonies such as this marked the Guardia's growing role in Nicaraguan civic and political life during the interwar period, a formative era for the institution that would shape the country's military and political history for decades to come.
