County Formation Maps

Idaho Maps are an invaluable part of family history research, especially if you live far from where your ancestor lived. Because Idaho political boundaries often change, historic maps are critical in helping you discover the precise location of your ancestor's hometown, what land they owned, who their neighbors were, and more. The Idaho State and County Formation Map begins in 1848 when it was a part of the northwest territory, and then follows through by year until the last county formation was created in February 1919. Idaho Territory was offically organized on March 4, 1863 with only one county formed, Owyhee county. Over the next 27 years, approximately 19 counties had been created before Idaho became the 43rd state on July 3, 1890.
