| − | By the mid-18th century, it was generally known that the northeastern Ozarks contained large quantities of lead, which the French and Spanish colonial authorities of the Louisiana Territory made efforts to exploit, as did some French traders and entrepreneurs operating out of [[St. Louis]] and Ste. Genevieve. The area of future Madison County lay within the Ste. Genevieve district, and the authorities there allowed some periodic mining operations, though these were generally short-lived. Permanent settlement began about 1799 along Saline Creek and the Little St. Francis River, these first arrivals being mostly farmers from the [[United States of America|United States]] and the existing French communities. Soon after 1800, a village was established near the Little St. Francis, by the name of St. Michael. It was also at this time that more extensive mining operations began at Mine La Motte, a few miles away.<ref>Robert Sidney Douglass, ''History of Southeast Missouri'' (1912), p. 63-64, 167.</ref> | + | By the early 18th century, it was generally known that the northeastern Ozarks contained large quantities of lead, which the French and Spanish colonial authorities of the Louisiana Territory made efforts to exploit, as did some French traders and entrepreneurs operating out of [[St. Louis]] and Ste.

| − | The lead mines were profitable enough that the population and prosperity of the region grew rapidly, boosted as well by local agriculture. The village of St. Michael, damaged by flooding, was eventually moved a short distance away onto higher ground and renamed Fredericktown in 1819. By this time, the Missouri territorial legislature had decided to organize it as a new county, which was officially formed on December 14, 1818 and named in honor of President Madison. Being near the center of the county, Fredericktown was soon chosen as the county seat. | + | The lead mines were profitable enough that the population and prosperity of the region grew rapidly, boosted as well by local agriculture.

Originally extending west to the Black River, the county had more or less assumed its present boundaries by 1867, after the western strip had been added to neighboring Iron County.<ref>https://shsmo.org/collections/manuscripts/ramsay/madison</ref> |
| | + | Madison County's development for a long time revolved around its mineral deposits. Besides lead (access to which would lead to some minor actions between [[Union]] and [[Confederate]] forces during the [[Civil War]]), veins of [[silver]], [[tungsten]], and [[wolframite]] have been discovered; mining for the latter two was especially important in the county during [[World War II]], when access to other deposits was cut off. Though most of the mining operations today are concentrated further north and west, with the last mine in the Fredericktown-Mine La Motte region closing in 1961, it continues to be an important element of the local economy.<ref>https://pubs.usgs.gov/sir/2008/5140/pdf/Chapter1.pdf</ref> |
