The first inhabitants in what is now Indiana were the Paleo-Indians, who arrived about 8000 BC after the melting of the glaciers at the end of the Ice Age. Divided into small groups, the Paleo-Indians were nomads who hunted large game such as mastodons. They created stone tools made out of chert by chipping, knapping and flaking.
The Archaic period, which began between 5000 and 4000 BC, covered the next phase of indigenous culture. The people developed new tools as well as techniques to cook food, an important step in civilization. These new tools included different types of spear points and knives, with various forms of notches. They made ground-stone tools such as stone axes, woodworking tools and grinding stones. During the latter part of the period, they built earthwork mounds and middens, which showed settlements were becoming more permanent. The Archaic period ended at about 1500 BC, although some Archaic people lived until 700 BC.
The Woodland period began around 1500 BC when new cultural attributes appeared. The people created ceramics and pottery and extended their cultivation of plants. An early Woodland period group named the Adena people had elegant burial rituals, featuring log tombs beneath earth mounds. In the middle of the Woodland period, the Hopewell people began to develop long-range trade of goods. Nearing the end of the stage, the people developed highly productive cultivation and adaptation of agriculture, growing such crops as corn and squash. The Woodland period ended around 1000 AD.
The Mississippian culture emerged, lasting from 1000 AD until the 15th century, shortly before the arrival of Europeans. During this stage, the people created large urban settlements designed according to their cosmology, with large mounds and plazas defining ceremonial and public spaces. The concentrated settlements depended on the agricultural surpluses. One such complex was the Angel Mounds. They had large public areas such as plazas and platform mounds, where leaders lived or conducted rituals. Mississippian civilization collapsed in Indiana during the mid-15th century for reasons that remain unclear.
The historic Native American tribes in the area at the time of European encounter spoke different languages of the Algonquian family. They included the Shawnee, Miami, and Illini. Refugee tribes from eastern regions, including the Delaware who settled in the White and Whitewater River Valleys, later joined them.
In 1679, French explorer René-Robert Cavelier, Sieur de La Salle was the first European to cross into Indiana after reaching present-day South Bend at the St. Joseph River. He returned the following year to learn about the region. French-Canadian fur traders soon arrived, bringing blankets, jewelry, tools, whiskey and weapons to trade for skins with the Native Americans.
By 1702, Sieur Juchereau established the first trading post near Vincennes. In 1715, Sieur de Vincennes built Fort Miami at Kekionga, now Fort Wayne. In 1717, another Canadian, Picote de Beletre, built Fort Ouiatenon on the Wabash River, to try to control Native American trade routes from Lake Erie to the Mississippi River.
In 1732, Sieur de Vincennes built a second fur trading post at Vincennes. French Canadian settlers, who had left the earlier post because of hostilities, returned in larger numbers. In a period of a few years, British colonists arrived from the East and contended against the Canadians for control of the lucrative fur trade. Fighting between the French and British colonists occurred throughout the 1750s as a result.
The Native American tribes of Indiana sided with the French Canadians during the French and Indian War (also known as the Seven Years’ War). With British victory in 1763, the French were forced to cede to the British crown all their lands in North America east of the Mississippi River and north and west of the colonies.
The tribes in Indiana did not give up: they captured Fort Ouiatenon and Fort Miami during Pontiac’s Rebellion. The British royal proclamation of 1763 designated the land west of the Appalachians for Native American use, and excluded British colonists from the area, which the Crown called “Indian Territory”.
In 1775, the American Revolutionary War began as the colonists sought self-government and independence from the British. The majority of the fighting took place near the East Coast, but the Patriot military officer George Rogers Clark called for an army to help fight the British in the west. Clark’s army won significant battles and took over Vincennes and Fort Sackville on February 25, 1779.
During the war, Clark managed to cut off British troops, who were attacking the eastern colonists from the west. His success is often credited for changing the course of the American Revolutionary War. At the end of the war, through the Treaty of Paris, the British crown ceded their claims to the land south of the Great Lakes to the newly formed United States, including Native American lands.
In 1787, the U.S. defined the Northwest Territory which included the area of present-day Indiana. In 1800, Congress separated Ohio from the Northwest Territory, designating the rest of the land as the Indiana Territory. President Thomas Jefferson chose William Henry Harrison as the governor of the territory, and Vincennes was established as the capital. After the Michigan Territory was separated and the Illinois Territory was formed, Indiana was reduced to its current size and geography.
Starting with the Battle of Fallen Timbers in 1794 and the Treaty of Greenville in 1795, Native American titles to Indiana lands were extinguished by usurpation, purchase, or war and treaty. About half the state was acquired in the Treaty of St. Mary’s from the Miami in 1818. Purchases were not complete until the Treaty of Mississinewas in 1826 acquired the last of the reserved Native American lands in the northeast.
A portrait of the Indiana frontier about 1810: The frontier was defined by the Treaty of Fort Wayne in 1809, adding much of the southwestern lands around Vincennes and southeastern lands adjacent to Cincinnati, to areas along the Ohio River as part of U.S. territory. Settlements were military outposts such as Fort Ouiatenon in the northwest and Fort Miami (later Fort Wayne) in the northeast, Fort Knox and Vincennes settlement on the lower Wabash. Other settlements included Clarksville (across from Louisville), Vevay, and Corydon along the Ohio River, the Quaker Colony in Richmond on the eastern border, and Conner’s Post (later Connersville) on the east central frontier. Indianapolis would not be populated for 15 more years, and central and northern Indiana Territory remained wilderness populated primarily by Indigenous communities. Only two counties in the extreme southeast, Clark and Dearborn, had been organized by European settlers. Land titles issued out of Cincinnati were sparse. Settler migration was chiefly via flatboat on the Ohio River westerly, and by wagon trails up the Wabash/White River Valleys (west) and Whitewater River Valleys (east).
In 1810, the Shawnee tribal chief Tecumseh and his brother Tenskwatawa encouraged other indigenous tribes in the territory to resist European settlement. Tensions rose and the U.S. authorized Harrison to launch a preemptive expedition against Tecumseh’s Confederacy; the U.S. gained victory at the Battle of Tippecanoe on November 7, 1811. Tecumseh was killed in 1813 during the Battle of Thames. After his death, armed resistance to United States control ended in the region. Most Native American tribes in the state were later removed to west of the Mississippi River in the 1820s and 1830s after U.S. negotiations and the purchase of their lands.
Corydon, a town in the far southern part of Indiana, was named the second capital of the Indiana Territory in May 1813 in order to decrease the threat of Native American raids following the Battle of Tippecanoe. Two years later, a petition for statehood was approved by the territorial general assembly and sent to Congress. An Enabling Act was passed to provide an election of delegates to write a constitution for Indiana. On June 10, 1816, delegates assembled at Corydon to write the constitution, which was completed in 19 days. Jonathan Jennings was elected the fledgling state’s first governor in August 1816. President James Madison approved Indiana’s admission into the union as the nineteenth state on December 11, 1816. In 1825, the state capital was moved from Corydon to Indianapolis.
Many European immigrants went west to settle in Indiana in the early 19th century. The largest immigrant group to settle in Indiana were Germans, as well as many immigrants from Ireland and England. Americans who were primarily ethnically English migrated from the Northern Tier of New York and New England, as well as from the mid-Atlantic state of Pennsylvania. The arrival of steamboats on the Ohio River in 1811, and the National Road at Richmond in 1829, greatly facilitated settlement of northern and western Indiana.
Following statehood, the new government worked to transform Indiana from a frontier into a developed, well-populated, and thriving state, beginning significant demographic and economic changes. In 1836, the state’s founders initiated a program, the Indiana Mammoth Internal Improvement Act, that led to the construction of roads, canals, railroads and state-funded public schools. The plans bankrupted the state and were a financial disaster, but increased land and produce value more than fourfold. In response to the crisis and in order to avert another, in 1851, a second constitution was adopted. Among its provisions were a prohibition on public debt, as well as the extension of suffrage to African-Americans.
During the American Civil War, Indiana became politically influential and played an important role in the affairs of the nation. Indiana was the first western state to mobilize for the United States in the war, and soldiers from Indiana participated in all the war’s major engagements. The state provided 126 infantry regiments, 26 batteries of artillery and 13 regiments of cavalry to the Union.
In 1861, Indiana was assigned a quota of 7,500 men to join the Union Army. So many volunteered in the first call that thousands had to be turned away. Before the war ended, Indiana had contributed 208,367 men. Casualties were over 35% among these men: 24,416 lost their lives and over 50,000 more were wounded. The only Civil War conflicts fought in Indiana were the Newburgh Raid, a bloodless capture of the city; and the Battle of Corydon, which occurred during Morgan’s Raid leaving 15 dead, 40 wounded, and 355 captured.
After the war, Indiana remained a largely agricultural state. Post-war industries included mining, including limestone extraction; meatpacking; food processing, such as milling grain, distilling it into alcohol; and the building of wagons, buggies, farm machinery, and hardware. However, the discovery of natural gas in the 1880s in northern Indiana led to an economic boom: the abundant and cheap fuel attracted heavy industry; the availability of jobs, in turn, attracted new settlers from other parts of the country as well as from Europe. This led to the rapid expansion of cities such as South Bend, Indianapolis, and Fort Wayne.
The early decades of the 20th century saw Indiana develop into a leading manufacturing state with heavy industry concentrating in the north. In 1906 the United States Steel Corporation created a new industrial city on Lake Michigan, Gary, named after Elbert Henry Gary, its founding chairman. With industrialization, workers developed labor unions (their strike activities induced governor James P. Goodrich to declare martial law in Gary in 1919) and a socialist party. Railroader Eugene Debs of Terre Haute, the Socialist candidate received 901,551 votes (6.0% of the national vote) in the 1912 presidential election. Suffrage movements also arose to enfranchise women.
In its earlier years, Indiana was a leader in the automobile boom. Beginning its production in Kokomo in 1896, Haynes-Apperson was the nation’s first commercially successful auto company. The importance of vehicle and parts manufacture to the state was symbolized by the construction in 1909 of the Indianapolis Motor Speedway.
In the 1920s, state politics was heavily influenced by the rise of the Indiana Klan. First organized in 1915 as a branch of the Ku Klux Klan, it appealed to white Protestants alarmed by social and economic trends, including changes induced by immigration from southern and central Europe. In the name of defending “hundred-per-cent Americanism”, the Klan sought exclude from public life “Bolsheviks, Catholics, Jews, Negroes, bootleggers, pacifists, evolutionists, foreigners, and all persons it considered immoral”.
By 1925 the Klan had 250,000 members, an estimated 30% of native-born white men. By 1925 over half the elected members of the Indiana General Assembly, the governor of Indiana, and many other high-ranking officials in local and state government were members of the Klan. Politicians had also learned they needed Klan endorsement to win office. That year, “Grand Dragon” D.C. Stephenson, who had begun to brag “I am the law in Indiana”, was charged and convicted for the rape and murder of Madge Oberholtzer, a young schoolteacher. Denied pardon, in 1927 Stephenson gave the Indianapolis Times lists of people the Klan had paid. Partly as a result of compounded scandal, membership collapsed.
Throughout the 1930s, Democrats were in power and “the Klan was political poison”. During those years, Indiana, like the rest of the nation, was affected by the Great Depression. The economic downturn had a wide-ranging negative impact on Indiana, such as the decline of urbanization. The Dust Bowl to the west led many migrants to flee to the more industrialized Midwest. Governor Paul V. McNutt’s administration struggled to build a state-funded welfare system to help overwhelmed private charities. During his administration, spending and taxes were both cut drastically in response to the Depression, and the state government was completely reorganized. McNutt ended Prohibition in the state and enacted the state’s first income tax. On several occasions, he declared martial law to put an end to worker strikes.
World War II helped lift Indiana’s economy, as the war required steel, food and other goods the state produced. Roughly 10% of Indiana’s population joined the armed forces, while hundreds of industries earned war production contracts and began making war material. Indiana manufactured 4.5% of total U.S. military armaments during World War II, ranking eighth among the 48 states. The expansion of industry to meet war demands helped end the Great Depression.
With the conclusion of World War II, Indiana rebounded to pre-Depression levels of production. Industry became the primary employer, a trend that continued into the 1960s. Urbanization during the 1950s and 1960s led to substantial growth in the state’s cities. The auto, steel and pharmaceutical industries topped Indiana’s major businesses. Indiana’s population continued to grow after the war, exceeding five million by the 1970 census. In the 1960s the administration of Matthew E. Welsh adopted its first sales tax of 2%. Indiana schools were desegregated in 1949. In 1950, the Census Bureau reported Indiana’s population as 95.5% white and 4.4% black. Governor Welsh also worked with the General Assembly to pass the Indiana Civil Rights Bill, granting equal protection to minorities in seeking employment.
On December 8, 1964, a Convair B-58 carrying nuclear weapons slid off an icy runway on Bunker Hill Air Force Base in Bunker Hill, Indiana and caught fire during a training drill. The five nuclear weapons on board were burned, including one 9-megaton thermonuclear weapon, causing radioactive contamination of the crash area.
Beginning in 1970, a series of amendments to the state constitution were proposed. With adoption, the Indiana Court of Appeals was created and the procedure of appointing justices on the courts was adjusted.
The 1973 oil crisis created a recession that hurt the automotive industry in Indiana. Companies such as Delco Electronics and Delphi began a long series of downsizing that contributed to high unemployment rates in manufacturing in Anderson, Muncie, and Kokomo. The restructuring and deindustrialization trend continued until the 1980s when the national and state economy began to diversify and recover.
