The American Legion was chartered by Congress in 1919 as a patriotic veterans organization. Focusing on service to veterans, servicemembers and communities, the Legion evolved from a group of war-weary veterans of World War I into one of the most influential nonprofit groups in the United States. Membership swiftly grew to over 1 million, and local posts sprang up across the country. Today, membership stands at over 2.4 million in 14,000 posts worldwide. The posts are organized into 55 departments: one each for the 50 states, along with the District of Columbia, Puerto Rico, France, Mexico and the Philippines. Mission statement - "To uphold and defend the constitution of the United States of America, to maintain law and order, to foster and perpetuate a one hundred percent Americanism, to pre serve the memories and incidents of our associations in the great wars, to inculcate a sense of individual obligation to the community, state and nation, to combat the autocracy of both the classes and the masses, to make right the master of might, to promote peace and good will on earth, to safeguard and transmit to posterity."
