The county is named for Judge Isaac Blackford, who was the first speaker of the Indiana General Assembly and a long-time chief justice of the Indiana Supreme Court. Created in 1838, Blackford County is divided into four townships, and its county seat is Hartford City. Two incorporated cities and one incorporated town are located within the county. The county is also the site of numerous unincorporated communities and ghost towns. Occupying only 165.58 square miles (428.9 km2), Blackford County is the fourth smallest county in Indiana. As of the 2010 census, the county's population is 12,766 people in 5,236 households. Based on population, the county is the 8th smallest county of the 92 in Indiana. Although no interstate highways are located in Blackford County, three Indiana state roads cross the county, and an additional state road is located along the county's southeast border. The county has two railroad lines. A north\u2013south route crosses the county, and intersects with a second railroad line that connects Hartford City with communities to the west. Before the arrival of European-American settlers during the 1830s, the northeastern portion of the future Blackford County was briefly the site of an Indian reservation for Chief Francois Godfroy of the Miami tribe. The first European-American pioneers were typically farmers that settled near rivers where the land had drainage suitable for agriculture. Originally, the county was mostly swampland, but more land became available for farming as the marshes were cleared and drained. Over the next 30 years, small communities slowly developed throughout the county. When the county's rail lines were constructed in the 1860s and 1870s, additional communities evolved around railroad stops. Beginning in the late 1880s, the discovery of natural gas and crude oil in the county (and surrounding region) caused the area to undergo an economic boom period known as the Indiana Gas Boom. Manufacturers relocated to the area to take advantage of the low-cost energy and railroad facilities. The boom period lasted about 15 years, and is reflected in Blackford County's population, which peaked in 1900 at 17,213. The new construction associated with the additional prosperity of the boom period caused a significant upgrade in the county's appearance, as wooden buildings were replaced with structures made with brick and stone. Much of the infrastructure built during that time remains today\u2014including Montpelier's historic Carnegie Library and many of Hartford City's buildings in the Courthouse Square Historic District. Agriculture continues to be important to the county, and became even more important after the loss of several large manufacturers during the 20th century. Today, 72 percent of Blackford County is covered by either corn or soybean fields; additional crops, such as wheat and hay, are also grown."
