DescriptionThe Montana legislature created Phillips County in 1915 from Blaine and Valley counties, with Malta as the county seat. The county takes its name from former Chouteau County senator Benjamin D. Phillips, who operated a sheep ranch and several area mines; Phillips used his political influence to ensure that the new county fell within the boundaries of his mining properties. Phillips County encompasses 6,565 square miles, making it one of Montana’s largest counties.Personal NamesPhillips, Benjamin D.Contributing InstitutionMontana Historical Society Library and ArchivesGeolocation[1] CountyPhillips County
