The Raging Controversy at the Border Began With This Incident 100 Years Ago

In early August 1918, Felix B. Peñaloza, the presidente municipal, or mayor, of Nogales, Mexico, ordered construction of a fence running along the boundary line between his city and Nogales, Arizona. The fence would consist of six wires strung to a height of six feet. His intent was to direct the flow of people crossing the border through two gateways, to make it easier for a growing number of soldiers, customs agents and other officials to oversee transborder movement. Peñaloza also met with U.S. representatives to discuss a second, parallel fence, to be built by the Americans. Mexican officials said they “would welcome the building of such a fence by the United States Government, as it would aid officials on both sides of the line in enforcing their regulations,” and they insisted that “such action would not be irritating or offensive to Mexican sentiment.”

Today a ten-mile-long rusted steel border wall is a defining feature of the cities. Its origin story begins with these two fences. When they were first erected in Nogales a century ago, they were neither a brazen political statement nor a barrier to immigrants, but a cooperative measure, embraced by both the United States and Mexico in the spirit of “good fences make good neighbors.” But the proposed American fence became what was most likely the first permanent barrier to control the movement of people across the U.S.-Mexico border.

Peñaloza’s fence cut through the heart of the twin cities of Nogales—known as Ambos Nogales, “Both Nogales.” Founded in 1882, Ambos Nogales became a bustling community centered on the boundary line, which ran along International Street. For years Mexicans and Americans crossed the border regularly to do business, shop, socialize and celebrate the holidays of both nations. Years later, former residents recalled how they had even played on the line as children.
