Deerfield Township’s name is derived from its many former
“deer licks” - springs that had a saline content that supported a large deer
population in the area. The township lies in the former Symmes or Miami
Purchase. Early settlement dates from the late 1790s. The township was
established on May 10, 1803.
Originally the township included more than half
of Turtlecreek Township, all of Union Township, and all of Salem Township north
of the Little Miami River. Today, Deerfield Township occupies the southwest
portion of Warren County. It is the most heavily developed township in the
During the first 40 years of its existence,
“Overseers of the Poor” were elected. Their function was to see to the welfare
of the township citizens who were unable to make a living. The “Overseers,” in
essence, “sold” the care of these citizens to the lowest bidder. The buyers
were then responsible for these citizens for a year. The township also had a
practice for some years of expelling those it thought would commit crimes
and/or become a burden on it. The township would issue warrants on these
individuals telling them to leave it.
In the early 1800s, the township was such an
important crossroads for travel and commerce that road building, linking it to
Cincinnati and points elsewhere, began soon after it was established. Later in
the 19th century, an organization was formed called “The Horse Rangers.” Its
mission was the maintenance of the laws of the township, the detection of
villainy and outlawry and the pursuit of the perpetrators. The group recovered
over 20 stolen horses and most of those involved in their thefts. This resulted
in similar group’s creation in the Twenty Mile Stand area in the southern part
of the township.
William Mason, a Revolutionary War veteran,
purchased a square mile of land in 1815 and platted it as Palymra. After his
death, the name of the town was changed to Mason. It was incorporated as a
village in 1840. Over the years, Mason grew quite substantially, covering more
than 11,000 acres. It was incorporated as a city in 1971 and in 1997 it
withdrew from the township.
The company that would become the King Powder
Company and Peters Cartridge Company began around 1850 by Ahimaaz King. By 1878,
it relocated to an area a few miles east of Mason in the sheltered valley of
the Little Miami River. Mr. King built a complete village, Kings Mill, for his
workers, with homes and schools for their families. During its period of
operation, the company experienced several major explosions and large fires.
The factories closed in 1958.
