Roger Eberhard | 100th Meridian Texas, 2016


For HOT MESS Roger Eberhard is exhibiting “100th Meridian Texas”, a large scale photograph from his “Human Territoriality” series. Across the globe and crisscross through the history of spatialized politics, this series strings together photographs of former demarcation lines.


100th Meridian, USA


The border between Mexico and the United States is 3,145 km long. With up to 350 million legal crossings a year, it is the world’s most frequently crossed border. Its history has been turbulent and remains politically fraught, thanks not least to current plans to build a wall along its entire length.

Under the Adams-Onís Treaty of 1819, Spain ceded Florida to the US in exchange for settling territorial disputes in Texas: the US relinquished all claims to the parts of Spanish Texas west of the Sabine River and to other Spanish areas. The treaty also established a US border running through the Rocky Mountains all the way to the Pacific Coastline. Part of this border ran along the 100th meridian between the Arkansas River and Red River.

This treaty had only been in effect for 183 days when Spain recognized Mexican independence in 1821. The Adams-Onís Treaty border was subsequently reestablished by Mexico and the US in the 1828 Treaty of Limits. It remained in place until 1836, when settlers in the region declared Texas an independent republic, which was soon recognized and incorporated into the United States in 1845, triggering the Mexican-American War (1846–1848). In 1848, the present boundaries were drawn in the Treaty of Guadalupe Hidalgo, making the Rio Grande the US’s southern border and ceding California, roughly half of New Mexico, Nevada, Utah, most of Arizona, as well as parts of Wyoming and Colorado to the US.


Roger Eberhard (b. 1984, Zurich) studied photography at the Brooks Institute in Santa Barbara, California, and at the Zurich University of the Arts.
