Dallam County History 1922, Occupying the extreme northwest corner of the Panhandle, Dallam County was for two-thirds of its area included in the great Capitol Syndicate holdings, and about fifteen years ago it was estimated that half the lands of the county were held in large tracts. Two railroad lines have encouraged development of agriculture and the breaking up of the big ranches, and in recent years the county has come to claim distinction as a productive center for all the staple Panhandle crops.
Dallam County was organized September 9, 1891. In 1888 the Fort Worth & Denver City Railway was built across the county to Texline, where the two divisions of the road were connected. Texline, close to the New Mexico boundary, was the original county seat. In 1900 the Rock Island Railroad was built across the county at right angles to the first line, intersecting at Dalhart, near the southern edge of Dallam County, with a portion of the larger city of today in Hartley County.
Texline was named the county seat when Dallam County was organized in 1891. Ten years later the railroad came, and a new town Dalhart sprang up at the railroad crossing. In 1903, Dalhart became the county seat. Dallam County’s first courthouse was built in 1891 in Texline. A second courthouse was built in Dalhart in 1903. The county’s current courthouse was built in 1923.
