Nationally, the YMCA Youth and Government Program began in New York State in 1936. In the mid-1930's, Clement A. Duran, the Boy's Work Secretary of the Albany YMCA, realized the government's need for more leaders of high moral character and integrity. At the same time he realized the need for high school youth to have a meaningful introduction to the democratic processes of government since they would soon become full-fledged adult citizens. Duran struck upon the idea of a Model Legislature as a program vehicle for introducing the youth to the actual processes and leadership of their state government. He hoped that such a highly meaningful experience might inspire the youth to think seriously about government as a career--or at least to stimulate the beginning of their active and concerned partitipation in government as a citizen. The slogan "Democracy Must Be Learned by Each Generation" was developed by Duran as a motto to interpret the purpose of the program.
With these goals in mind, he successfully developed the first YMCA Youth and Government Program with the help of William H. Burger for members of New York Hi-Y and Tri-Hi-Y clubs (high school age YMCA members) in 1936. The first Model Legislature was held that year in Albany, New York. With encouragement from the National Council of YMCAs, the program rapidly spread to other nearby states. Today, over 40 states have YMCA Youth and Government programs.
