On October 20, 1837, Vermont changed its flag to a design based on the current 13-stripe U.S. flag, but with the multiple stars of the blue canton replaced with a single large star surrounding Vermont’s coat of arms. The flags based on these specifications varied in the number of points on the star (five and eight, with eight slightly more common), and the exact details of the center of the star (with either the Great Seal or the coat of arms being used).
Because of confusion between the striped Vermont state flag and the U.S. flag, the design of the Vermont Governor’s flag was adopted as the official state flag on June 1, 1923.[1]
State Nickname – The Green Mountain State:
The origin of the name “Vermont” is uncertain, but likely comes from the French Les Verts Monts, meaning “the Green Mountains”.
Thomas Young introduced it in 1777. In 1913, the Secretary of State of Vermont speculated that the archaic French term Verd Mont (green mountain) may have inspired Young. Another source points out the predominance of mica-quartz-chlorite schist, a green-hued metamorphosed shale, as a possible reason. The Green Mountains form a north–south spine running most of the length of the state, slightly west of its center.
