The Girls' Brigade is an international, interdenominational Christian youth organisation founded in 1893 in Dublin, Ireland. The modern organisation was formed as the result of the 1964 consolidation of three organisations: the Girls' Brigade of Ireland (1893), the Girls' Guildry of Scotland (1900), and the Girls' Life Brigade of England (1902). The international headquarters are currently based in Derbyshire, England.
 The organisation operates internationally and is divided into five Fellowships: African, Asian, Caribbean and Americas, European, and Pacific. International conferences have been held every four years since 1998. Conferences were held in Australia in 1988, Thailand in 2002, Northern Ireland in 2006, Malaysia in 2010, Australia in 2014, and Zambia in 2018.  
 The Queen Mother and Princess Alice were Girls' Brigade's patrons until their deaths in 2002 and 2004, respectively. From 1983 until her death in 2020, Olive Hilda Miller was Vice-Patron of Brigade International.
 The international vision statement is "Girls' lives transformed, God's world enriched."
 The Girls' Brigade's principles are "to proclaim Jesus Christ as The Saviour, and to fulfill his aim by living the values that he taught, promoting a society where all people are equally valued."[citation needed]
 The motto of the Girls' Brigade is "Seek, serve and follow Christ", and its aim is "to help girls become followers of the Lord Jesus Christ and through self-control, reverence and a sense of responsibility to find true enrichment of life." Since 1936, the Girls' Brigade has been a founding member of The National Council for Voluntary Youth Services (NCVYS) . 
 The Girls' Brigade program in many countries follows four themes: Spiritual, Physical, Educational, and Social. The four themes of the program are based on a passage from Luke 2:52: "And Jesus grew in body and wisdom, gaining favor with God and men." The Physical theme is in relation to Jesus growing in body, educational in relation to Jesus growing in wisdom, spiritual is in him growing closer to God and the social is the way that Jesus develops in his relationships with men. During their time in the Girls Brigade and throughout their lives after the girls are encouraged to participate in activities other than just badge work. These include leadership courses for 14 to 21-year-olds, and most companies or districts arrange camps or holidays, usually one per year. Moreover, the Girls' Brigade helps its members with the Duke of Edinburgh Award scheme.
 The Girls' Brigade provides weekly activities, social engagement projects, summer camps, residential training events, and mission trips.

 The crest is a registered trademark of Girls' Brigade England & Wales. However, all Girls' Brigade companies around the world have the right to use it. 
 In the center is a cross, the symbol of Christianity. Below the cross is a lamp, which represents the Girls' Brigade. Above it is a crown, symbolising monarchy in general and Christ the King in particular. Behind it all is a torch; fire is a typical sign in Christianity of God's presence.
 In 1965, the Girls' Brigade (formed 1893 in Ireland), the Girls' Guildry (formed 1900 in Scotland), and the Girls' Life Brigade (formed 1902 in England) combined into the modern Girls' Brigade. At the time, a competition was held to design the crest for the amalgamated organisation. Constance Fasham, the winner of the competition, incorporated symbols from each partner organisation: the cross from the Ireland Girls' Brigade, the lamp from the Girls' Guildry, and the crown from the Girls' Life Brigade. 
 Fasham intended the badge to incorporate symbols from the three original organizations. The badge was intended therefore as a symbol of union and Christian faith.
