According to the Ohio Secretary of State;
Ohio’s official flag was adopted by an act of the Ohio Legislature on May 9, 1902. The Ohio burgee (bûr’je), as the swallow-tailed design is properly called, was drawn by John Eisenmann, architect and designer for the Ohio State Pan-American Exposition Commission.
Pledge
In 2002, in celebration of the 100th anniversary of the adoption of the Ohio flag, the Ohio General Assembly adopted a pledge to the Ohio flag for the first time in state history. The pledge, “I salute the flag of the state of Ohio and pledge to the Buckeye State respect and loyalty,” can be recited following the pledge of allegiance to the American flag.

The flag of the state shall be burgee-shaped. It shall have three red and two white horizontal stripes that represent the roads and waterways of the state. The union of the flag shall be seventeen five-pointed stars, white in a blue triangular field that represents the state’s hills and valleys, the base of which shall be the staff end or vertical edge of the flag, and the apex of which shall be the center of the middle red stripe. The stars shall be grouped around a red disc superimposed upon a white circular “O.” The thirteen stars grouped around the “O” represent the original states of the United States and the four stars added to the peak of the triangle symbolize that Ohio was the seventeenth state admitted to the union. The “O” represents the “O” in “Ohio” and suggests the state’s nickname, the buckeye state. The proportional dimensions of the flag and of its various parts shall be according to the official design on file in the office of the secretary of state. One state flag of uniform dimensions shall be furnished to each company of the organized militia.
