The Anti-Defamation League (ADL) is the world's leading organization fighting anti-Semitism and hate. Founded in the early 20th century, ADL addresses all forms of intolerance, including anti-Semitism, extremism and terrorism, and uses our extensive research capabilities to expose and counter hate globally. Harnessing diverse tools such as education, legal briefs, law enforcement training and legislative advocacy, ADL is a leading voice for the preservation of human rights and democratic principles. Since its inception, ADL has believed it is important to apply the methods developed in the fight against anti-Semitism to counter hate in all communities. We use our comprehensive understanding of how hate evolves to foster respect for differences and build communities of respect.
With our nearly 100-year history of monitoring and analyzing trends in anti-Semitism, ADL remains at the forefront of establishing and implementing the most effective methods to counteract hate, whether in online research or new techniques in diversity education. From our early history fighting yellow journalism, employment and housing discrimination and lynching, ADL is now on the cutting edge in using the Internet to prosecute hate and in developing statutes and education methods to combat cyberbullying. ADL's research, legal and education tools are considered essential by educators, law enforcement officials, policy makers, and Jewish communities in the U.S., Israel and around the world.
