The Rio Grande, demarcating the U.S./Mexico border, is more than a geographical feature; it now embodies division and fortification, reflecting a historical process of weaponization. This proposed project traces the term Border, as it has evolved in the political perceptions of the Rio Grande. Through the gathering of historical testimonies, from its portrayal as a battleground in the Spanish-Ameican War to leisure activities in the 1960s, this project will highlight select narratives and uncover how border enforcement and economic development have reshaped relationships with the river, both visually and temporally. Amid headline focus on violence and political tensions, following the term "border" in this context reveals a deeper perspective that is essential for our understanding of complex histories and ultimately, how we may address it now.
