Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Seymour’s 268 sits above most of its state (91% of Indiana towns have fewer) while its 599 historic buildings outnumber those of 98% of U.S. towns.

The land around Seymour was inhabited by the Lenape (Delaware), who had been displaced westward from the Delaware River valley. The 1805 Treaty of Grouseland opened the area to white settlement. After the 1812 Pigeon Roost massacre, the Battle of Tipton's Island took place, where Major John Tipton and some thirty men overcame a larger party of Native raiders. Native Americans killed fifteen settlers between 1811 and 1815, and by 1816—the year Indiana attained statehood—only five families remained in the area. In 1817 the state built a blockhouse to trade with the Lenape until they ceded the land under the 1818 Treaty of St. Mary's, after which the county saw significant depopulation between 1822 and 1832.
