Following thousands of years of varying cultures of indigenous peoples, the historic Miami and
Delaware Indians (a.k.a. Lenape) are the first-recorded permanent settlers in the Blackford County area, living on the
Godfroy Reserve after an 1818
treaty. The site is located in Blackford County's Harrison Township, east of
Montpelier. Although the Godfroy Reserve was allotted to Miami Native Chief
Francois (a.k.a. Francis) Godfroy, Delaware Indians were also allowed to stay there. The Miami tribe was the most powerful group of Natives in the region, and Francois Godfroy (who was half French) was one of their chiefs. By 1839, Godfroy had sold the reserve, and the Natives had migrated west. He entered the area on July 9, 1831. Reasoner and his sons built the county's first
mill, on their farm. The land that would become Blackford County was originally the western part of Jay County. A January 30, 1836, act of the Indiana General Assembly created Jay County, effective March 1, 1836. In December 1836, a motion was made in the Indiana House of Representatives to review dividing Jay County, but that resolution was not adopted. Two Blackford County communities, Matamoras and Montpelier, originally existed as part of Jay County. They lie along the Salamonie River in what became the northeast portion of Blackford County. John Blount founded Matamoras, arriving in 1833. This village is Blackford County's oldest community, and is the site of the county's largest water mill. Several sources list the creation year for Blackford County as 1837. However, the law was not finalized until 1838. Indiana bill of the House No. 152 was originally for the creation of a county named Windsor. The name "Windsor" was replaced with the name "Blackford" by the House of Representatives in January 1838. An "act for the formation of the county of Blackford" was approved on February 15, 1838. This act intended that the county would be "open for business" on the first Monday in April 1838, which was April 2. However, the county was not organized. Finally, on January 29, 1839, the original February 15 act was amended, stating that Blackford County shall "enjoy the rights and privileges" of an independent county. The act also appointed commissioners, and corrected a misprint that defined the southeast corner of the new county. When it was noted that another Indiana community was also named Hartford, Blackford County's Hartford was renamed Hartford City. During the next 25 years, the county grew slowly. Plans were made for roads and railroads, and swampland was drained. The first railroad line was authorized in 1849. The plan was for the Fort Wayne & Southern Railroad Company to connect the Indiana cities of
Fort Wayne and
Muncie—running north–south through the Blackford County communities of Montpelier and Hartford City. Although construction began in the 1850s, it was not completed (by connecting Fort Wayne to Muncie) until 1870, and this delay caused it to be the second railroad to operate in Blackford County. The first railroad to operate in Blackford County crossed somewhat east–west through the county's southern half. The railroad was named Union and Logansport Railroad Company by the time it entered Blackford County. A portion of this line is now abandoned, and the track has been removed between Converse and Hartford City, south of
State Road 26.
Gas boom In 1886,
natural gas was discovered in two counties adjacent to Blackford County. The discoveries were in the small community of
Eaton (south of Hartford City along railroad line) in Delaware County, and in the city of
Portland in Jay County (east of Hartford City and Millgrove). The Hartford City Gas & Oil Company was formed in early 1887, and successfully drilled a natural gas well later in the year. The Montpelier Gas & Oil Mining company was organized in 1887. Montpelier was thought to be "the very heart of the greatest natural gas and oil field in the world". By 1896, Blackford County had 18 natural gas companies, headquartered in all four of the county's townships, including the communities of Hartford City, Montpelier, Roll, Dunkirk, Trenton (Priam Post Office), and Millgrove. In June 1880, only 171 people held manufacturing jobs in Blackford County. The Indiana Gas Boom transformed the region, as manufacturers moved to the area to utilize the natural gas and railroad system. During 1901, Indiana state inspectors visited 21 manufacturing facilities in Blackford County, and these companies employed 1,346 people (compare to 171 two decades earlier). Since these inspections were in Hartford City and Montpelier only, additional manufacturing employees from the county's small communities (such as
Millgrove's glass factory) could be added to the count of 1,346. The county's two largest employers were glass factories:
American Window Glass plant number 3 and
Sneath Glass Company. In addition to an economic transformation, another byproduct of the gas boom was an upgrade of Blackford County's appearance. Many of the county's landmark buildings were constructed during the gas boom, including the
current courthouse and surrounding buildings in Hartford City's Courthouse Square Historic District. The city's water supply system was also built during that period. Additional buildings include the Carnegie Library, and the historic
Presbyterian Church. Many of Montpelier's Downtown Historic District structures were built during the gas boom. Montpelier's historic
Baptist Church and Montpelier's Carnegie Library were constructed in the early 1900s – near the end of the gas boom.
Post-gas boom The Indiana Gas Boom ended during the first decade of the 20th century, reducing the county's economy. Gas and oil workers left, some manufacturers moved, and service industries were forced to cut back operations. Adding to the county's problems, machines made the labor–intensive method originally used for producing window glass obsolete, causing many of the county's skilled glass workers at the large American Window Glass plant to lose their jobs. By 1932, the window glass plant of the county's former largest employer was closed. According to the United States Census, Blackford County's population peaked at 17,123 in 1900, and it still has not returned to that zenith over 100 years later. For other communities, such as Mollie, the loss of the gas and oil workers meant that the local post office was a "waste of time", and
consumer demand at the general store was significantly diminished. The improved quality of automobiles and roads competed with passenger service on the railroads (and interurban lines), causing a decline in passenger traffic on the rails. Small towns associated with railroad stations suffered from the loss in traffic. In Blackford County, passenger service on the Lake Erie and Western Railroad line (owned by the
Nickel Plate Road by that time) was discontinued in 1931, and the last interurban train ran on January 18, 1941. Hartford City leaders attracted businesses such as
Overhead Door (1923) and
3M (1955) to replace the former companies.{{#tag:ref|Grant's Overhead Door article in volume 70 of the
International Directory of Company Histories has been reproduced on a web page. Agriculture continues to be an important factor in the county's economy. Over 70 percent of Blackford County's land is occupied by
soybean or
corn fields. Additional crops and livestock are also raised. Good returns in agriculture are not always reflected in the economy of nearby towns, as industrial agriculture has reduced the number of workers it needs, and family farms have declined. Many small towns in the "
Corn Belt", such as the communities in Blackford County, continue to decline in size and affluence. ==Geography==
