In 1896, the Holy Rosary Catholic Church was established in the growing European-American settlement. Most of the people were Acadian, so the main language was French. The town was named after Abrom Kaplan, who bought the Jim Todd Plantation in 1901. The town Kaplan grew quickly and was established in 1902. The following year, residents created the first school.
The Kaplan Herald has been in continuous publication since 1956 as the Kaplan Journal. When Conrad Kaplan purchased the newspaper in 1965, he named it the Kaplan Herald.
