SLB, then known as the Namfrel Marines, began in 1986 during the EDSA Revolution as a network of the religious, individuals, and groups that aimed at safeguarding ballots and ensuring clean and credible elections. It developed as a non-profit organization, under the guidance of the Society of Jesus in the Philippines, with the mission of upholding and promoting social justice through its good governance advocacy and disaster risk reduction and management programs.
