On December 11, 1811, the county lines between Washington County, Montgomery County, and Laurens County were adjusted by the Georgia General Assembly. The northern section of Montgomery between the Oconee River and theOhoopee River was transferred to Laurens. On December 10, 1812, the county line of Montgomery was significantly adjusted as part of the creation ofEmanuel County. Its new boundaries became from the thenLaurens andTelfair county line on theOconee River to the north prong of theLittle Ocmulgee River (near presentChauncey, Dodge County, Georgia) down the Little Ocmulgee River as it meanders to its confluence with theOcmulgee River then downstream as it meanders to the Oconee River, then North 30 degrees to Milligan's Creek in Tatnall County, and then with it to the Montgomery County line.[4] Pendleton Creek (in modern Treutlen and Toombs counties) was used as the border between Montgomery and Emanuel. Because of these transitions Montgomery regained part of the land it had lost in the creation of Tatnall County in 1801 (land along the lower Oconee River), but also lost land along the upper Oconee River to Laurens County.
The creation of Emanuel County put the old county seat within Emanuel's border. On December 12, the Georgia General Assembly appointed the justices of the inferior court of Montgomery county to a commission to designate a new county seat and called for county business to be held until then at the home of James Alston. In 1813, the General Assembly recognizedMount Vernon as the new county seat.
The county line between Telfair County and Montgomery was adjusted once again in 1820 by the Georgia Genera Assembly. The new line differed in the upstream portion of the Little Ocmulgee River and better defined the line and gave Montgomery a small border withPulaski County, Georgia and Telfair County some land on the northeast side of the Little Ocmulgee River. The line was to go upstream to its fork then to Browning's mill, a straight line to the mouth of Joiner's Creek (Near modernMcRae, Georgia) at the second fork of the Little Ocmulgee River, and then up the second prong to Pulaski County Line.[5]
The land gained by Telfair County from Montgomery County on the northeast side of the Little Ocmulgee River was reversed by the Georgia General Assembly on December 18, 1833.[6]
At the time of the 1850 United States Census, Montgomery had 1,541 whites, 613 slaves. By the 1860 census, there were 2,014 whites, 977 slaves, and 6Free people of color. The pine barrens andsoil quality outside of the river lands made the area unsuitable for slave-heavy cotton producing plantation culture. Montgomery's status as a majority white county led the region developing different attitudes about secession from other areas of Georgia.
On January 22, 1861, Montgomery County representatives, Thomas M. McRae and Solon Homer Latimer, were among the 89 delegates who voted no to Georgia's immediate secession from the Union at the state secession convention. In addition, McRae and Latimer were among the 6 delegates who voiced their protest by against theOrdinance of Secession in the published document.
In the interior of the county aroundGum Swamp (ModernChauncey, Georgia) near the Pulaski County, Telfair County, and Montgomery County lines a deserter gang fought against Confederate forces.[7]
On August 18, 1905, Montgomery County gained and lost some territory during the creation ofToombs County. On August 14, 1912, the parts of Montgomery County between theLittle Ocmulgee River and theOconee River becameWheeler County. On August 21, 1917, Montgomery lost additional territory during the creation ofTreutlen County, Georgia.
More recently, the county was noted for its practice of organizingsegregated proms, a practice that had continued since integration of its schools in the 1970s.[8][9][10] Following publicity about this practice, Montgomery County students took the initiative to integrate the prom in 2010.[11]
According to theU.S. Census Bureau, the county has a total area of 245 square miles (630 km2), of which 240 square miles (620 km2) is land and 5.2 square miles (13 km2) (2.1%) is water.[12]
The southeastern quarter of Montgomery County is located in theAltamaha River sub-basin of the larger river basin by the same name. The western half of the county, fromTarrytown south, is located in the LowerOconee River sub-basin of the Altamaha River basin. The northeastern quarter of Montgomery County, northeast of a line from Tarrytown toHiggston, is located in theOhoopee River sub-basin of the same Altamaha River basin.[13]
