Emmet was founded in 1882 on the Fremont, Elkhorn and Missouri Valley Railroad. It was named after Irish nationalist Robert Emmet. Currently, the population is 48 and is described as a town with good people, good land, and good clean air -- three reasons people choose to live here.
Like much of Holt County, the Emmet area is well suited for production of wild hay. Early settlers cut it as a cash crop. In the 1920's, the Emmet-Elkhorn Valley Hay Company was founded. It's name was later abbreviated to the Emmet Hay Company. The community describes itself as the "Biggest Little Haytown in the World".
