History
Hyde County was created by the territorial legislature on January 8, 1873, with area partitioned from Buffalo County. It was not organized by that action. Its boundaries were altered by changes in October 1879 and February 1883. On November 5, 1883, the county organization was filled and the county was placed in independent operation.[3]
The current Hyde County courthouse was constructed in 1911 (it is currently listed on the National Register of Historic Places). The county organization included a jail until 1974, when the jail was abandoned and jail-related services were contracted to surrounding counties.[5]
Geography
The county terrain consists of semi-arid rolling hills, partly devoted to agriculture. The Missouri River flows southeastward at its SW corner, and delineates a portion of the county's south boundary line.[6]
The terrain slopes toward the county's SW corner. Its highest point is on the lower part of its eastern boundary line, at 2,080 ft (630 m) ASL.[7]
Hyde County has a total area of 866 square miles (2,240 km2), of which 861 square miles (2,230 km2) is land and 5.6 square miles (15 km2) (0.6%) is water.[8]

Politics
Hyde County voters have been reliably Republican ever since South Dakota's statehood. In only two national elections – the Democratic landslides of Franklin D. Roosevelt in 1932 and Lyndon B. Johnson in 1964 – has the county ever voted for a Democratic presidential candidate – although in the Republican landslides of 1956 (due to a major drought and resultant agricultural problems) and 1972 (due to a strong “favorite son” vote for George McGovern) the county actually voted about 4 points more Democratic than the nation at-large.
