Initially designated “Township 5, Range 3” of the Connecticut Western Reserve, Bazetta is the center township of Trumbull County and was founded in 1804, one year after Ohio statehood.

One of the last townships to be developed, Bloomfield includes two homes listed on the National Register of Historic Places: Brownwood (circa 1819) and Charles Brown Gothic Cottage (circa 1846), both well known “stations” on the Underground Railroad.

One of the most important "associative" settlements ever attempted in the country, the Trumbull Phalanx, was located here. This communal society experiment lasted nearly a decade. In addition to a grist mill, a bow and arrow factory, wagon shop, a shoe shop and other industries, the area also included a hotel. In the 1840s, a Pennsylvanian opened a store near the Mahoning River and called its location "The Center of the World," a name that continues to intrigue visitors today.

Ohio’s first Civil War memorial, the Civil War Monument, is located here. Erected in 1863, it features emblems of various military branches and the names of 14 men who gave their lives in the Union cause at Shiloh, Tennessee and Perryville, Kentucky.

According to some historians, this was the first area in Trumbull County that was settled, as early as 1796. In the 1800s, the local population surpassed Warren and tripled that of neighboring Sharon, Pennsylvania. Also known as “Little Canada”, the township was a haven for lawbreakers such as John Dillinger, Clyde Barrow and Ma Barker.

This area was slow to grow when first settled thanks to the high land prices demanded by the owner, Henry Champion. However, following his death, the prices went down and the area was rapidly settled. The first township meeting was held in the 1830s in the William Woodrow brick home, which still stands near the corner of Champion Avenue and State Route 45. Known today as Mahoning Avenue, this major road was called the Warren-Ashtabula Turnpike, where tolls were once collected.

First called Baconsburg, and later Leroy Village, this city was once home to the area’s only grist mill, located along Walnut Creek. In 1942, Mosquito Creek was dammed to create Mosquito Creek Reservoir. Today the city of Cortland abuts the east side of this large recreational and wildlife area.

Thanks to its location and proximity to the Mahoning River and the Pennsylvania & Ohio Canal and then later to the railroads, Girard grew into a manufacturing and transportation center. In addition to steel and other heavy industry, tanneries played a prominent role in the growth of the city. Although Squaw Creek Park, which was built in 1896 as a trolley park and later called Avon Oaks, is long gone, its grand ballroom still stands. Today Avon Oaks Ballroom still attracts people, with one of the largest wooden dance floors in Ohio. The story about Girard and its history can be found at the Henry Barnhisel House Museum (circa 1840), which is operated by the Girard Historical Society. 

Incorporated in 1868, Hubbard’s prosperity was attributed to coal mining and the manufacturing of iron. The largest mercantile establishment and company store for the furnace and coal companies, the George M. McKelvey Company, was located here in the late 1870s. The Ohio Bicentennial Barn for Trumbull County can be seen at 7763 East Liberty Street. 

Once home to two covered bridges, only one remains. Located a half-mile west of the Warren-Ravenna Road and known as the “East” bridge, the surviving bridge was built in 1831 and is the only remaining wooden covered bridge in Ohio with an outside pedestrian walkway. The Mahoning River Waterfalls is located in the city's Veterans Park.

More commonly known as the birthplace of the 25th President of the United States, William F. McKinley, Niles was also hometown to Harry M. Stevens, who is credited with the creation of the hot dog as well as the baseball scorecard and the drinking straw. Today Eastwood Field, which sits adjacent to the Eastwood Mall Entertainment Complex, plays host to the Mahoning Valley Scrappers, a New York-Penn Class-A affiliate team of the Cleveland Indians.

Now the county seat for Trumbull County, Warren was originally the capital of the Connecticut Western Reserve. The historic Trumbull County Courthouse (circa 1897) graces the Courthouse Square Park and sits amidst downtown storefronts and eateries. Throughout the year, the park is the site of many local events and festivals. The Warren Community Amphitheatre overlooking the Mahoning River offers one of the city's newest outdoor venues. Along historic Millionaire's Row are stately homes and mansions that were built by the city's affluent in the 1800s and have been restored to their original grandeur. Recognized as national treasures, many of these structures are now home to businesses, museums and offices, including the Perkins Mansion, which has served as City Hall since 1934. The achievements and legacies of the innovative Packard family can be found throughout the city, including Packard Music Hall, which hosts local and national entertainment and events, and the National Packard Museum, which chronicles the history of the Packard automobile, the Packard family and the Packard Electric Company.

Originally known as Henshaw Township, Farmington became a bustling community in the 19th and early 20th centuries as the Grand River and one of the region’s first railroad lines ran through the township.

Fowler is one of the oldest communities in Trumbull County. Its historic district includes State Routes 193 and 305, the Fowler Town Hall (circa 1850) and the David Butts Home, built in 1852 and now a museum displaying the township’s pioneer past. The oldest structure in the township is the Craft House (circa 1825), located on Everett-Hull Road near Cortland. 

Much of the land here is comprised of Mosquito Lake and the surrounding wetlands and preserves, making it the second-smallest township in Trumbull County. In the mid-1800s, development of the area increased when a stagecoach line ran from Cleveland through the township on its way to Meadville, Pennsylvania. Hotels and taverns, including the Liberty Raymond Tavern, which was also a stop on the Underground Railroad, were built to serve the travelers. However, after a few years the route was discontinued, the hotels and taverns closed and the township residents turned their attention to agriculture and dairy farming

Twelve buildings in this community are listed on the National Historic Registry, classifying this area as a national historic district. Additionally, Gustavus became the first township in the United States to build a centralized school and three locations, including the George Hezlip House and Store, the Stoddard Stevens Store and the Presbyterian Parsonage, had connections to the Underground Railroad

Known for its annual Apple Festival held in September and Sharon Speedway, owned by NASCAR driver Dave Blaney and his family, this area remains rural and is supported by agriculture.

One of the oldest structures in the township is the Sealy House, which was home of the area’s first physician, John Sealy, who not only served as an Ohio representative and state senator but a general in the War of 1812. Howland Springs Company, which is thought to be the oldest-operating business in the country, is also located here. It was developed in the 1850s as a health spa resort and included a hotel that contained the first bowling alley west of the Appalachian Mountains.

The first framed house in the township, which is still standing on Bentley Avenue, was built in 1808. The discovery of coal in 1861 brought an influx of new settlers to the most southeast township in Trumbull County, including the Welsh, whose knowledge of coal mining helped secure them work in the newly discovered mines.

Captain James Johnston, a veteran of both the Revolutionary War and the War of 1812, was the township’s first proprietor. One of the first major emergencies to face the early settlers of this area was the typhus fever that struck in 1811. As a result of the vast number of deaths, the outbreak limited the number of well citizens to care for the sick.

Trumbull County’s most northeast township, which is bordered by Ashtabula County and the state of Pennsylvania, is named for John Kinsman, the township’s first surveyor who came to the area in 1799. Other notable citizens included Ernest Lyman, who made the first useable extract of insulin for the treatment of diabetes; Josiah Yeomans, credited with making the first corn-brooms; Joseph Badger, a Massachusetts-born Revolutionary War veteran and cloth weaver turned preacher; and Clarence Darrow, the nationally renowned lawyer who is most remembered for his defense of a schoolteacher's right to teach Darwin's Theory of Evolution in 1925. Darrow's childhood home, the eight-sided Octagon House, still stands on Main Street, and although it is privately owned, it is available for tours by advanced request.

Some history books list this township as the largest coal-mining township in the country, with 17 mines operating at the same time. From the start of mining in 1860 until its end in 1906, the population of this area nearly tripled.

Due to the swamp-like conditions, Mecca was not only one of the last areas to be settled but it was also the least settled. Even before the first settler arrived there in the early 1800s, Native Americans had fled the area years before because of the swampy land. However, that changed in 1859, when oil was discovered. Hundreds of people from all over the country flocked to the area. Hotels, stores, boarding houses and residences were built, and between 600 and 700 wells were drilled. But by 1865, the boom died almost as suddenly as it began. Today, Mecca is a popular spot for outdoor enthusiasts, thanks in part to the Mosquito Creek Reservoir and the State Route 88 causeway.

This area, along with Middlefield in adjacent Geauga County, boasts the second-largest Amish settlement in Ohio and the fourth-largest in the country. The center of town, better known as the “Commons”, is surrounded by 28 buildings — 21 of them built before the Civil War — and is included on the National Register of Historic Places as a Historic District. The End of the Commons General Store has been in continuous operation since the 1840s.

Located in the southwest corner of Trumbull County, this area is home to two branches of the Mahoning River, which were important during the township’s early days for both travel and commerce. A number of mills built along the river made use of the swift-moving water for power.

The unusual five-way intersection of Warren-Burton Road and State Routes 534 and 305 was the location of most of the homes, businesses and churches when this area was first settled. Hurd’s Store, which was built in 1865, still sits at the intersection and has been operated by five generations of the Hurd family.

Most of the earliest settlers in this area came from Connecticut and farming was the major industry. The early rural farms provided milk, cheese, butter and other goods to residents of Trumbull County and neighboring Pennsylvania. Today, farming remains the major industry.

Having been the last of the original 25 townships to be settled in Trumbull County in 1822, Lordstown became the County’s youngest political unit in 1975, when its citizens voted to replace a township form of government with a municipality by incorporating as a village. Although Lordstown has remained mostly rural through the years, it is home to General Motors' Lordstown Complex, the manufacturing site for the Chevrolet Cobalt.

McDonald’s history began when the Carnegie Steel Company bought 118 acres of pastureland in Weathersfield Township to develop a village for its workers. Known as a “company town”, McDonald later incorporated in 1918. In 1941, the steel company sold the the land in the village to a developer who then sold the land and houses to the residents. That same developer began a new housing development in 1950 that consisted of 225 prefabricated homes.

This community is actually divided by the Ohio and Pennsylvania state line. Legend has it that because there are so many churches on the Pennsylvania side, that while performing a wedding ceremony, the minister would ask the bride and groom to leave the church and then pronounce them married on the white line in the middle of the road!

The population growth of this area began in the early 1800s and centered in the city of Warren and also Leavittsburg. As transportation routes were developed, many rail lines made Leavittsburg a center for railroad activity. State Route 422 was the area's first highway link with Cleveland, and brought commerce into the township. Today the area is mostly residential.

As early as 1755, men from Pennsylvania came to this area to extract salt from the springs located here. It was the same reason that the Native Americans who had been removed by troops from Fort Pitt in Pittsburgh lived here. However, it was later determined that there was not enough concentration of salt to be prosperous and as a result, the springs were covered over. Glazed earthenware was manufactured here beginning in 1816, and coal was mined from the mid 1850s to 1888.
