Set in the summer of 1869 along the Green and Colorado Rivers through the Grand Canyon, Men on Boats takes place at the pivotal moment in American history. The Civil War had ended only four years earlier, and the nation was in the midst of Reconstruction under President Ulysses S. Grant, who took office in March 1869. Although the 13th and 14th Amendments had legally abolished slavery and granted citizenship to formerly enslaved Black Americans, racial violence and white resistance remained intense, revealing a country struggling to define freedom and national unity. At the same time, the ideology of Manifest Destiny continued to justify westward expansion as divinely sanctioned progress. The completion of the Transcontinental Railroad in May 1869 and policies like the Homestead Act accelerated migration, land privatization, and economic development, while Indigenous nations were being forcibly removed, confined to reservations, and subjected to broken treaties rooted in earlier legislation such as the Indian Removal Act. Within this political and economic climate, exploration was not merely scientific curiosity but a tool of federal expansion and national myth-making. Powell’s expedition thus reflects a broader effort to reassert American strength, masculinity, and unity after the civil war, while simultaneously erasing indigenous presence and transforming land into property. The play’s humor and satire expose how “discovery” in 1869 was inseparable from conquest, capitalism, and the construction of heroic national narratives.
