In 1860 Fillmore was Minnesota's most populous county.[6]
Fillmore County is on Minnesota's border withIowa. TheRoot River drains the county, flowing eastward. The North Branch and the Middle Branch combine east of Shady Creek, while the South Branch meets their combined flow at Preston. Bear Creek drains the lower part of the county, discharging into the Root in the eastern part of the county. Willow Creek also drains a portion of the lower county, discharging into the Root at Preston. TheUpper Iowa River flows eastward, mostly in adjoining Iowa counties, but briefly enters Fillmore County near the midpoint of its southern border.
The county's terrain consists of rolling hills, carved by gullies and drainages, with the available area dedicated to agriculture.[7] The terrain slopes to the east; its highest point is on the lower western border, at 1,378 ft (420 m) ASL.[8] The county has a total area of 862 square miles (2,230 km2), of which 861 square miles (2,230 km2) is land and 0.8 square miles (2.1 km2) (0.09%) is water.[9]

Fillmore County's political history is fairly typical of manyYankee-settled rural counties in the Upper Midwest. In the early 1990s, the transition of the Republican Party into a party largely based around Southern Evangelicals severely alienated its historic Yankee base: Fillmore County turned to Democrat Bill Clinton in 1992, and voted Democratic in every election between 1992 and 2012. However, concern with unemployment, immigration, and trade deals in the “Farm Belt” resulted in a powerful swing to Republican Donald Trump in 2016, with Hillary Clinton showing the worst Democratic performance in the county since George McGovern in 1972. Fillmore County has voted for Donald Trump by more than 20% each time.
