Hamazkayin (Armenian: Համազգային), short for Hamazkayin Armenian Educational and Cultural Society, is a major cultural organization of the Armenian Diaspora, with a presence in every significant Armenian community worldwide. In addition to organizing cultural events in local Armenian communities, the Hamazkayin runs three schools, publishes books through its printing press, maintains bookstores, publishes a monthly literary magazine, Pakin (Armenian: Բագին), and organizes the Hamazkayin Forum. Hamazkayin enjoys the support of a wide segment of the Armenian community and encourages active participation to the events sponsored by the community. Hamazkayin sponsors and organizes many cultural events, such as concerts by renowned artists, scientific seminars, film festivals, literary lectures and book reviews. In the United States, the Hamazkayin Armenian Educational and Cultural Society was established as a non profit organization in 1970.
