The Chicago River was once so polluted that it caught on fire several times in the mid-20th century. The river was so polluted with chemicals and sewage that it was almost devoid of life. Today, the river has been cleaned up and is a popular spot for recreational activities like kayaking and boat tours.
Kankakee County, located in northeastern Illinois, has a rich history dating back thousands of years. Before European settlement, the area was inhabited by Native American tribes, including the Potawatomi and Miami tribes. These tribes primarily lived off the land, utilizing the Kankakee River Valley for farming, hunting, and fishing.

The first European settlers arrived in the early 19th century, establishing small farming communities in what is now Kankakee County. In 1834, the county was officially established, named after the Kankakee River that flows through the area. The introduction of the Illinois Central Railroad in the 1850s played a pivotal role in the county's development, facilitating trade and attracting more settlers to the region.

Kankakee County experienced significant growth and industrialization in the late 19th and early 20th centuries. The arrival of the Chicago and Eastern Illinois Railroad in 1871 further boosted the economy, expanding transportation and enabling the establishment of various industries. Factories, including those in the apparel, steel, and machinery sectors, flourished, providing employment opportunities for residents.

The 20th century brought both challenges and growth for Kankakee County. The Great Depression of the 1930s impacted the local economy, leading to closures and job losses. However, World War II sparked a period of economic recovery and expansion, as defense industries thrived. The county experienced suburbanization in the latter half of the century, with more people moving from Chicago to the surrounding areas. Today, Kankakee County continues to evolve, maintaining its agricultural roots while also embracing diverse industries such as healthcare, transportation, and technology.
