Founded in the 1830s and developed during the mid-19th Century as a major port for riverboats, Cairo was once considered to be one of the most important sites for urban settlement in the United States, due to its location at the confluence of the Mississippi River and Ohio River, which are the two main branches, by volume, of the longest navigable inland waterway system on the North American continent. The city grew rapidly during the early decades, but due to the city’s late start in development due to its flood-prone location and issues with land companies, the increase in importance of railroads, and various other economic factors, the city never reached the lofty ambitions that its founders and early residents envisioned. Nevertheless, by the time of the US Civil War, the city was a major river port, and became home to Fort Defiance, a United States Army fortification, which was located south of the city proper at the present site of Fort Defiance State Park. After the Civil War, the city continued to grow, eventually becoming a regional center with a population of over 15,000 by the 1920s, boasting a significant business district along Washington Avenue, Commercial Avenue, and the side streets between them, with theaters, hotels, restaurants, shops, department stores, and other amenities that drew in residents of surrounding towns and rural areas. However, after World War II, racial tensions began to mount in the city, which had a high degree of racial segregation, and in the 1960s, these tensions exploded into violence between the city’s White population, which owned most of the businesses and property in town, in addition to holding disproportionate political power in Cairo and Alexander County, and the long-neglected Black community, whom lived in substandard housing and were not allowed to patronize many of the town’s White-owned businesses. Riots broke out in 1967 in response to the mysterious death of Robert Hunt, a Black man, while in police custody, and again in in the summer of 1969, when the White Hats, deputized White private citizens, clashed violently with the Cairo United Front, whom represented the city’s Black community, demanding equal treatment and equal rights. In 1970, activists picketed outside White-owned businesses, which were boycotted by the city’s Black population, leading to the demise of much of the town’s remaining commercial enterprises, with White business owners often electing to close up shop and move elsewhere. In the wake of the unrest, and due in part to other economic and social factors, most of the town’s businesses closed, with economic activity shifting to other towns and cities in the region, leaving the downtown area a fading relic of a bygone era. Today, the town has shrunk to 1,500 people, with vacant grassy lots and rubble from long-demolished buildings lining many of the streets, including the formerly bustling Commercial Avenue and Washington Avenue. Cairo is a ghost town on the river, and despite its important location, has been forgotten. Fort Defiance State Park reflects this in its present condition, with dilapidated facilities, and an overall lack of visitor amenities, which is, in part, due to the state of Illinois giving control of the park to the struggling city of Cairo in the 1990s, which lacked the resources to properly steward it. The state regained control of the park in 2014, but it seemingly has been overlooked, and very little has been done to significantly improve the visitor experience. The Mississippi River and Ohio River, which are two of the most significant features of the United States and have massively shaped the country’s history, demographics, and economy, gave rise to many communities along their banks, many of which had aspirations of greatness. However, many, like Cairo, have since faded into obscurity. Today, Cairo’s only claim to fame, besides its sheer level of abandonment and urban decay, is that it sits at the junction of the two largest branches, by water volume, of the Mississippi River system, waters that fed the growth of America’s civilization, industry, and population.
