Elias Boudinot, a Cherokee citizen working as a lobbyist in Washington, D.C., published an article about the public land issue in the February 17, 1879 edition of the "Chicago Times". Dr. Morrison Munford of the "Kansas City Times" began referring to this tract as the "Unassigned Lands" or "Oklahoma" and to the people agitating for its settlement as "Boomers". Munford is the first person to use the terms "boom" and "boomer" to describe the movement of white settlers into these lands. To prevent settlement of the land, President Rutherford B. Hayes issued a proclamation in April 1879 forbidding unlawful entry into Indian Territory.
