Seth Bullock and Teddy Roosevelt first met each other in 1884 when the future president spent time in North Dakota. After the candidate Roosevelt wanted elected by the Republican party failed to be nominated he abandoned politics and headed out west. This first meeting was the start of a friendship that would last decades. Bullock was later brought on by Roosevelt as part of a volunteer cavalry regiment during the Spanish-American War and again as part of a volunteer infantry division during World War 1.
