Philadelphia is called the “City of Brotherly Love” because its very name comes from the Greek words for love (“philia”) and “brother” (“adelphos”). Over time, that phrase has become both a nickname and a kind of moral challenge for how the city sees itself.

Name and origin

  • The word “Philadelphia” was chosen in 1681 by founder William Penn, a Quaker who wanted his colony to embody religious tolerance and mutual respect.
  • In Greek, “philia” means affectionate or friendly love and “adelphos” means brother, so “Philadelphia” literally translates to “brotherly love.”

Ideal vs. real city

  • Historians describe Philadelphia as an “unfinished dream” of civic feeling, noting that its history includes both powerful examples of solidarity and painful episodes of conflict and inequality.
  • Public institutions like parks, libraries, settlement houses, and the city’s mural arts program are often held up as signs of that brotherly-love ideal made visible in everyday civic life.

Modern vibe of “brotherly love”

  • Residents and writers frequently say that the longer you live in Philadelphia, the more the phrase “City of Brotherly Love” starts to feel accurate, pointing to a strong sense of community, especially compared with larger, more anonymous cities.
  • At the same time, the city is known for passionate sports fans and a sometimes tough, “prickly” attitude, which locals often see as just another expression of loyalty and pride in their home.
