France did not accept Greenwich meridian as prime meridian for as long as three decades. The Paris meridian, which runs through the Paris Observatory, was a long standing rival to the Greenwich meridian to be selected as the prime meridian of the world. In fact, the Paris meridian has been used by French cartographers as prime meridian for two centuries. In October 1884, at the behest of US president Chester Arthur, 25 nations met at the International Meridian Conference, and voted for Greenwich meridian as the official prime meridian. France abstained from voting and continued to use the Paris meridian till 1914.
