At that time, developers purchased land and platted the town of Dwight, which was named for Dwight Rathbone who donated land for the Methodist Episcopal Church. The community was settled about the time the railroad was built and a post office was established in March 1887. The Chicago, Kansas, & Nebraska Railway was foreclosed in 1891 and taken over by Chicago, Rock Island & Pacific Railway.
By the turn of the century, Dwight had developed into a trading and shipping point in the northeastern part of Morris County. By that time it had a money order post office with two rural routes, express, telegraph, and telephone service, three churches, and good public schools. The town was incorporated in 1905 and in 1910 had a population of almost 300 people. Throughout the years the Presbyterian and Methodist churches played an important part in the life of the community. The town’s population peaked at 365 in 1990.
Dwight schools were closed through school unification and local grade school children now attend school in Alta Vista, while middle and high school students attend classes in Council Grove. Today the trains that continue through the community are operated by the Union Pacific Railroad.
Today, Dwight continues to be a small town with a population of about 260 people. The Swartz School Museum, which once stood about 2.5 miles to the southwest of town, is now located on Main Street.
Dwight is located about 17 miles northwest of Council Grove.
