Prime Meridian: Why Greenwich?

Subject: Static GK (General Knowledge)

Book: General Time Knowledge

The prime meridian at Greenwich, England, became the internationally accepted zero-longitude line in 1884. This decision followed centuries of competing meridians in Paris, Rome, and elsewhere. Britain’s naval dominance and comprehensive mapping efforts positioned Greenwich as a global standard. Establishing the prime meridian facilitated uniform time zones and shipping charts. While some nations initially resisted, most eventually adopted the Greenwich-based system for the sake of seamless trade. Understanding why Greenwich was chosen clarifies how historical power dynamics shape global conventions.
