18th century

The borough was incorporated in 1795 and was named for William "Bill" Lewis, a Quaker and a member of the legislature, who was responsible for the designation of the borough, which was then known as the Village of Ohesson, as the county seat of Mifflin County.^[6]

19th century

During the late 19th century Mifflin County became the crossroads of the Commonwealth. Located near the geographic center of the state, the area became a hub for traffic moving in every direction. Early roads crisscrossed the region, but it was the eventual construction of the Pennsylvania Canal and the railroads that followed that truly positioned Mifflin County as an economic force in the state.

Lewistown, as the major city in Mifflin County, saw its economy expand dramatically as entrepreneurs launched companies to construct canal boats or build inns offering lodging for travelers and workers.

At its zenith, Mifflin County was one of the busiest centers for cargo and passenger traffic in the United States. But with the demise of the canal system, Mifflin County eventually lost its place as a major transportation hub.

On April 16, 1861, as the American Civil War broke out, Lewistown sent its Logan Guards, a militia group formed in 1858, to defend the national capital of Washington, D.C. They were one of only five companies, all recruited in Pennsylvania, to share the honor of being the first U.S. troops sent to the capital. Monument Square, situated at the intersection of Main and Market Streets in Lewistown, serves as a memorial to these men.

20th century

Lewistown lost its role as a major transportation hub, but still boasted a strong industrial economy into the 1970s, when the county's industries began a slow decline.

Hurricane Agnes June 1972 crippled the local economy. On June 19, Hurricane Agnes made initial landfall along the Florida Panhandle as a weak Category 1 Hurricane. Agnes then proceeded through Georgia, South Carolina and North Carolina before she moved back over the Atlantic off the North Carolina coast on June 21.

After regaining strength over the Atlantic, she made landfall again over southeastern New York on June 22 and moved westward in an arc over southern New York into north-central Pennsylvania. She became nearly stationary over Pennsylvania by morning of June 23, but was soon absorbed by a low-pressure system that slowly drifted northeastward from Pennsylvania into New York.

Rainfall from storm over the Mid-Atlantic region ranged from 2 to 3 inches (51 to 76 mm) in the extreme upper basins of the Potomac and North Branch Susquehanna Rivers to 18 inches (460 mm) near Shamokin, Pennsylvania, in the Main Stem Susquehanna River basin. An average of 6 to 10 inches (150 to 250 mm) of rain fell over the Mid-Atlantic region. The soil, already well watered by spring rains, could not absorb so much water so quickly.

While flooding from the Juniata River was somewhat controlled due to a dam at Raystown Lake, 44 miles (71 km) west of Lewistown, the county experienced extensive flooding from the river and major streams which resulted in the permanent closure of many businesses along the river. Most notably, the flood submerged much of the American Viscose Corporation plant, then a division of FMC Corporation. The facility, located on the banks of the Juniata River across from Lewistown proper, manufactured rayon fiber (primarily for rayon-belted automobile tires), polyester and Avistrap.

FMC was one of two major employers in the area at the time, the other being the Standard Steel Works. The Viscose plant was only marginally profitable before the storm and the cost to reopen was prohibitive. The demand for rayon fabric for trendy clothing shot upward only a few years later. Rayon production, and with it, thousands of good-paying jobs, moved to another FMC plant in Front Royal, Virginia. The Lewistown polyester plant reopened, but it rehired only a fraction of the previous workforce. The site eventually became the Mifflin County Industrial Plaza and a variety of businesses have come and gone since then.

In the wake of the failure of Lewistown's industry, a long period of decline began. The 1990s saw the loss of several plants, including Masland and Lear, and Standard Steel filing for reorganization bankruptcy.

21st century

The early 2000s saw the loss of Scotty's Fashions, Mann Edge Tool, Overhead Door shuttering its sectional division, and Ford New Holland shuttering its Belleville plant which also led to the closing of the Belleville Foundry.

In 2011, Standard Steel merged with Japanese company Sumitomo Industries and is now known as Nippon Steel; this merger effectively saved the jobs of 500 union laborers as well as many others in the area. First Quality, an adult incontinence products manufacturer, opened a facility in Lewistown that employs approximately 400 people. Geisinger purchased Lewistown Hospital in 2013 and expanded services including a helicopter pad, the Geisinger LIFE program and a new clinic in nearby Reedsville.

In the 2020s, Lewistown has seen growth in new small businesses by young entrepreneurs, including restaurants and retail. The construction of an enhanced highway system between Lewistown and State College was completed in 2020 and better connects the two communities.
