The Toledo War (1835–1836), also known as the Michigan–Ohio War or Ohio–Michigan War, was a boundary dispute between the state of Ohio and the adjoining Michigan Territory over the Toledo Strip. Control of the Maumee River's mouth was seen by both parties as a valuable economic asset, due to the inland shipping opportunities that it offered and the good farmland to the west.
Poor geographical understanding of the Great Lakes helped to produce conflicting state and federal legislation between 1787 and 1805, and varying interpretations of the laws led the governments of both Ohio and Michigan to claim jurisdiction over a 468-square-mile (1,210 km2) region along their border. The situation came to a head when Michigan petitioned for statehood in 1835 and sought to include the disputed territory within its boundaries, and both sides passed legislation attempting to force the other side's capitulation. Ohio Governor Robert Lucas and Michigan's 24-year-old "Boy Governor" Stevens T. Mason both instituted criminal penalties for residents submitting to the other's authority. Both states deployed militia forces on opposite sides of the Maumee River near Toledo, Ohio, but there was little interaction between the two forces apart from mutual taunting. The single military confrontation of the war ended with a report of shots being fired into the air, incurring no casualties. The only blood spilled was the non-fatal stabbing of a law enforcement officer.
During the summer of 1836, the United States Congress proposed a compromise whereby Michigan gave up its claim to the strip in exchange for its statehood and the remaining three-quarters of the Upper Peninsula. While the northern region's mineral wealth would become an economic asset to Michigan, the compromise was considered a poor deal at the time for Michigan, and voters soundly rejected it the following September. The Michigan government was facing a dire financial crisis and pressure from Congress and President Andrew Jackson, so it convened what was called the "Frostbitten Convention" to accept the compromise and resolve the Toledo War.
Origins
In 1787, the Congress of the Confederation enacted the Northwest Ordinance, which created the Northwest Territory in what is now the upper Midwestern United States. The Ordinance specified that the territory was eventually to be divided into "not less than three nor more than five" future states. One of the boundaries between them was to be "an east and west line drawn through the southerly bend or extreme of Lake Michigan". When Congress passed the Enabling Act of 1802, which authorized Ohio to begin the process of becoming a U.S. state, the language defining Ohio's northern boundary elaborated on that, but was fundamentally the same: "an east and west line drawn through the southerly extreme of Lake Michigan, running east ... until it shall intersect Lake Erie or the territorial line [with British North America, now Canada], and thence with the same through Lake Erie to the Pennsylvania line aforesaid".
The most highly regarded map of the time, the "Mitchell Map", showed the southerly extreme of Lake Michigan at a latitude north of the mouth of the Detroit River, suggesting that an east–west line would not intersect with Lake Erie at all, until well across the international border. The framers of the 1802 Ohio Constitution therefore believed it was the intent of Congress that Ohio's northern boundary should certainly be north of the mouth of the Maumee River, and possibly even of the Detroit River. Ohio would thus be granted access to most or all of the Lake Erie shoreline west of Pennsylvania, and any other new states carved out of the Northwest Territory would have access to only Lakes Michigan, Huron, or Superior.
However, the delegates allegedly received reports from a fur trapper that Lake Michigan extended significantly farther south than had previously been believed (or mapped). Thus, it was possible that an east–west line extending east from Lake Michigan's southern tip might intersect Lake Erie somewhere southeast of Maumee Bay, or worse, might not intersect the lake at all; the farther south that Lake Michigan actually extended, the more land Ohio would lose, conceivably even the entire Lake Erie shoreline west of Pennsylvania.
Addressing this contingency, the Ohio delegates included a provision in the draft Ohio constitution that if this report about Lake Michigan's position was correct, the state boundary line would be angled slightly northeast so as to intersect Lake Erie at the "most northerly cape of the Miami [Maumee] Bay". This provision would guarantee that most of the Maumee River watershed and the southern shore of Lake Erie west of Pennsylvania would fall in Ohio. The draft constitution with this proviso was accepted by the United States Congress, but before Ohio's admission to the Union in February 1803, the proposed constitution was referred to a Congressional committee. The committee's report stated that the clause defining the northern boundary depended on "a fact not yet ascertained" (the latitude of the southern extreme of Lake Michigan), and the members "thought it unnecessary to take it [the provision], at the time, into consideration."
When Congress created the Michigan Territory in 1805, it used the Northwest Ordinance's language to define the territory's southern boundary, disregarding that provision in Ohio's state constitution. This difference, and its potential ramifications, apparently went unnoticed at the time, but it established the legal basis for the conflict that would erupt 30 years later.
Creation of the Toledo Strip
The location of the border was contested throughout the early 19th century. Residents of the Port of Miami—which would later become Toledo—urged the Ohio government to resolve the border issue. The Ohio legislature, in turn, passed repeated resolutions and requests asking Congress to take up the matter. In 1812, Congress approved a request for an official survey of the line. Delayed because of the War of 1812, it was only after Indiana's admission to the Union in 1816 that work on the survey commenced. At that time, the border between Michigan and Indiana was altered from the Northwest Ordinance boundary – over the protests of the Michigan Territory – moving it 10 miles (16 km) northward to give the new state substantial frontage on Lake Michigan.
U.S. Surveyor General Edward Tiffin, who was in charge of the survey, was a former Ohio governor, and employed William Harris to survey not the Ordinance Line, but the line described in the Ohio Constitution of 1802. When completed, the "Harris Line" placed the mouth of the Maumee River completely in Ohio, as intended by the drafters of the state constitution. When the results of the survey were made public, Michigan territorial governor Lewis Cass objected, writing in a letter to Tiffin that the survey was biased to favor Ohio and "is only adding strength to the strong, and making the weak still weaker."
In response, Michigan commissioned a second survey that was carried out by John A. Fulton. The Fulton survey was based upon the original 1787 Ordinance Line, and after measuring the line eastward from Lake Michigan to Lake Erie, it found the Ohio boundary to lie just southeast of the mouth of the Maumee River. The region between the Harris and Fulton survey lines formed what is now known as the "Toledo Strip". This ribbon of land between northern Ohio and southern Michigan spanned a region five to eight miles (8 to 13 km) wide, over which both jurisdictions claimed sovereignty. While Ohio refused to cede its claim, Michigan quietly occupied it for the next several years, setting up local governments, building roads, and collecting taxes throughout the area.
Economic significance
The Toledo Strip was (and still is) a commercially important area. Prior to the rise of the railroad industry, rivers and canals were the major "highways of commerce" in the American Midwest. A small but important part of the Strip—the area around present-day Toledo and Maumee Bay—fell within the Great Black Swamp, and this area was nearly impossible to navigate by road, especially after spring and summer rains. Draining into Lake Erie, the Maumee River was not necessarily well-suited for large ships, but it did provide an easy connection to Indiana's Fort Wayne. At the time, there were plans to connect the Mississippi River and the Great Lakes through a series of canals. One such canal system approved by the Ohio legislature in 1825 was the Miami and Erie Canal that included a connection to the Ohio River and an outflow into Lake Erie via the Maumee River.
During the conflict over the Toledo Strip, the Erie Canal was built, linking New York City and the Eastern seaboard to the Great Lakes at Buffalo. The canal finished in 1825, and immediately became a major route for trade and migration. Corn and other farm products (from the Midwest) could be shipped to eastern markets for much less expense than the older route along the Mississippi River. In addition, the migration of settlers to the Midwest increased sharply after the canal was finished, turning Buffalo and other port cities into boomtowns.
The success of the Erie Canal inspired many other canal projects. Because the western end of Lake Erie offered the shortest overland route to the frontiers of Indiana and Illinois, Maumee Harbor was seen as a site of immediate importance and great value. Detroit was 20 miles (32 km) up the Detroit River from Lake Erie, and faced the difficult barrier of the Great Black Swamp to the south. Because of this, Detroit was less suited to new transportation projects such as canals, and later railroads, than was Toledo. From this perspective on the rapidly developing Midwest of the 1820s and 1830s, both states had much to gain by controlling the land in the Toledo Strip.
In addition, the Strip west of the Toledo area is good for agriculture, because of its well-drained, fertile loam soil. The area had for many years produced large amounts of corn and wheat per acre. Michigan and Ohio both wanted what seemed strategically and economically destined to become an important port and prosperous farmland.
Prelude to conflict
In 1820–21, the federal land surveys had reached the disputed area from two directions, progressing southward from a baseline in Michigan and northward from one in Ohio. For unknown reasons, Surveyor General Tiffin ordered the two surveys to close on the Northwest Ordinance (Fulton) line, rather than Harris' line, perhaps lending implicit support to Michigan's claims over Ohio's. Thus, townships that were established north of the line assumed they were part of the Michigan Territory. By the early 1820s, the growing Michigan Territory reached the minimum population threshold of 60,000 to qualify for statehood. When it sought to hold a state constitutional convention in 1833, Congress rejected the request because of the still-disputed Toledo Strip.
Ohio asserted that the boundary was firmly established in its constitution and thus Michigan's citizens were simply intruders; the state government refused to negotiate the issue with them. The Ohio Congressional delegation was active in blocking Michigan from attaining statehood, lobbying other states to vote against it. In January 1835, frustrated by the political stalemate, Michigan's territorial governor Stevens T. Mason called for a constitutional convention to be held in May of that year, despite Congress's refusal to approve an enabling act authorizing one.
In February 1835, Ohio passed legislation that set up county governments in the Strip. The county in which Toledo sat would, later in 1835, be named after incumbent Governor Robert Lucas, a move that further exacerbated the growing tensions with Michigan. Also, during this period, Ohio attempted to use its power in Congress to revive a previously rejected boundary bill that would formally set the state border to be the Harris Line.
Michigan, led by the young and hot-headed Mason, responded with the passage of the Pains and Penalties Act just six days after Lucas County was formed; the act made it a criminal offense for Ohioans to carry out governmental actions in the Strip, under penalty of a fine up to $1,000 (equivalent to $31,000 in 2025), up to five years imprisonment at hard labor, or both. Acting as commander-in-chief of the territory, Mason appointed Brigadier General Joseph W. Brown of the Third U.S. Brigade to head the state militia, with the instructions to be ready to act against Ohio trespassers. Lucas obtained legislative approval for a militia of his own, and he soon sent forces to the Strip area. The Toledo War had begun.
Former United States President John Quincy Adams, who at the time represented Massachusetts in Congress, backed Michigan's claim. In 1833, when Congress rejected Michigan's request for a convention, Adams summed up his opinion on the dispute: "Never in the course of my life have I known a controversy of which all the right was so clearly on one side and all the power so overwhelmingly on the other."
War
Acting as commander-in-chief of Ohio's militia, Governor Lucas—along with General John Bell and about 600 other fully armed militiamen—arrived in Perrysburg, Ohio, 10 miles (16 km) southwest of Toledo, on March 31, 1835. Shortly thereafter, Governor Mason and General Brown arrived to occupy the city of Toledo proper with around 1,000 armed men, intending to prevent Ohio advances into the Toledo area as well as stopping further border marking from taking place.
