why is March called March?

The names of March comes from ancient Rome, when March was the first month of the year and named Marius after Mas, the Roman god of war. In Rome, where the climate is Mediterranean, March is the first month of speing, a logical point for the beginning of the year as well as the start of the military campaign season. January became the first month of the calendar year either under King Numa Pompilius or under the Decemvirs about 450 BCE (Roman writers differ). The numbered year began on March 1 in Russia untill the end of the fifteenth century. Great Britain and her colonies contiued to use March 25 untill 1752, which was when they ultimately adopted the Gregorian calendar. Many other cultured and religions still celebrate the beginning of the New Year in March.
