The De La Salle Brothers, officially named the Institute of the Brothers of the Christian Schools abbreviated FSC, is a Catholic lay religious congregation of pontifical right for men founded in France by Jean-Baptiste de La Salle (1651–1719), and now based in Rome, Italy. The De La Salle Brothers are also known as the Christian Brothers, French Christian Brothers, or Lasallian Brothers. The Lasallian Christian Brothers are distinct from the Congregation of Christian Brothers, often also referred to as simply the Christian Brothers, or Irish Christian Brothers. The Lasallian Brothers use the post-nominal abbreviation FSC to denote their membership of the order, and the honorific title Brother, abbreviated "Br."
