It may have the same roots as the original hammer and Plough that was replaced by the hammer and sickle in Soviet Russia.[citation needed] The significance of the banner was that the free Workers of the Republic of Ireland would control its own destiny from the plough to the stars and the sword forged into the plough would mean the redundancy of war with the establishment of a socialist International. The flag depicts the Big Dipper, part of the constellation of Ursa Major that is known as "The Plough" in Ireland and Great Britain.[citation needed] The Plough is one of the most prominent features of the night sky over Ireland throughout the year. This was unveiled in 1914 and flown by the socialist workers' militia (the Irish Citizen Army) during the 1916 Easter Rising.
