B'nai B'rith International, founded in 1843, is the world's oldest and most widely known Jewish humanitarian, advocacy and social action organization, with a presence in over 50 countries. The organization's Charter established that "B'nai B'rith has taken upon itself the mission of... developing and elevating the mental and moral character of the people of our faith; of inculcating the purest principles of philanthropy, honor and patriotism; of supporting science and art; visiting and attending the sick; coming to the rescue of victims of persecution; [and] providing for, protecting and assisting the aged, widows and orphans on the broadest principles of humanity."
Among B'nai B'rith's wide-ranging historic accomplishments are the establishment of the Anti-Defamation League, the campus organization Hillel, Jewish Women International (previously B'nai B'rith Women), and the youth movement BBYO. B'nai B'rith efforts and services, as well as facilitation of dialogue, has benefited not only Jews but also Christians and members of numerous other communities -- leaders and grassroots -- in a variety of ways and in many parts of the globe.
