HISTORY MOMENTS The Idaho State Historical Society reports that during this week in history: The Constitutional Convention convened on May 25, 1787, in Philadelphia under the leadership of George Washington, in order to establish a new U.S. government. The United States Congress established a new territory of Montana on May 26, 1864, from what then was northeast Idaho, and set the present Idaho-Montana boundary by statute. Although legend has it that surveyors got drunk and did not know what they were doing or were bribed by unscrupulous Montana agents, the boundary was fixed clearly and definitely where it is now years before the actual surveying took place in 1904-1906. On May 26, 1868, President Andrew Johnson avoided conviction for impeachment charges of "high crimes and misdemeanors" by one vote. Boise chartered a street railway company on May 28, 1890. In 1905 construction began on new lines destined to connect Boise, Nampa, Caldwell, and other commercial centers and farming areas. Eventually, consolidated into a single system, Boise Valley's interurban rail service continued for two decades before cars became so popular that traffic declined and operation became unprofitable. The Titanic was launched on May 31, 1911, in Belfast. At the ceremony, a White Star Line employee claimed, "Not even God himself could sink this ship." It was General John A. Logan, first commander of the Grand Army of the Republic, who issued the following order establishing Decoration Day honoring the Civil War dead. "The 30th of May, 1868, is designated for the purpose of strewing flowers, or otherwise decorating the graves of comrades who died in defense of their country during the late rebellion, whose bodies now lie in almost every city, village and hamlet churchyard in the land." At the end of World War I, the name was changed to Memorial Day and it became an observance to honor all Americans who died in war.
