History of Nogales

style="mso-bidi-font-style:italic">Los Nogales de Elías. Following the Gadsden purchase in 1853, Nogales became a part of the United States of America. In 1880, Russian immigrant Jacob Isaacson built a trading post at present-day Nogales. The U.S. Postal Service opened the Isaacson post office but renamed it as Nogales in 1883.

On August 27, 1918, a battle between United States Army forces and Mexican militia - mostly civilian in composition - took place. Culminating as the result of a decade's worth of tensions originating from the Mexican Revolution and earlier battles in Nogales along the border in 1913 and 1915, the main consequence of the 1918 violence saw the building of the first permanent border wall between Nogales, Arizona, and Nogales, Sonora, along the previously unobstructed boundary line on International Street
