In the 1973-74 fiscal year, due to its continued growth, the AYF split into three separate administrative entities: the Western US, Eastern US, and Canada. The Western Region was centered in California and became a haven for the youth of these growing Armenian communities.
By 1978, AYF Camp Big Pines was purchased in the Angeles National Forest. With its close proximity to the Los Angeles area, the camp provided a unique environment for young Armenians to make new friends, become better acquainted with their history and culture, and participate in a wide array of activities.
In that same year, Haytoug, the official publication of the AYF-Western Region, was created. It was published to serve as a forum in which Armenian youth could write about relevant contemporary issues. The articles often emphasized the need for youth to be active and engaged within their communities.
The AYF also continued its various educational programs, social gatherings, athletic competitions, and community activism. Both on a chapter and central level, the AYF brought Armenian youth together to build bonds of friendship, raise awareness of relevant social issues, promote civic activism, assist the homeland, establish educational forums, and advance the Armenian Cause.
Beginning in the late 1980s, the struggle for the independence of Artsakh became a new challenge for the AYF. The organization became involved in fundraising activities to supply much-needed funds to the Armenians of Artsakh. Following the ceasefire in 1993, the AYF continued to aid Artsakh by establishing the Youth Corps program in 1994. The mission of the program was not only to aid in rebuilding the nation, but more importantly to create a bond between Armenian youth in the Diaspora and the homeland.
