The Veterans of Foreign Wars Post 2070 Arcadia-Monrovia was chartered on April 11, 1931. The post belongs to District 11, Department of California, and the National VFW organization. 
On May 10, 2004, Post 2070 merged with Duarte Post 7483, assuming its membership, but retaining its name and post number. On April 11, 2021, Post 2070 celebrated its 90-year charter anniversary. 
The Veterans of Foreign Wars of the United States is a nonprofit veterans service organization comprised of eligible veterans and military service members from the active, guard and reserve forces. 
The organization traces its roots back to 1899 when veterans of the Spanish-American War and the Philippine Insurrection founded local organizations to secure rights and benefits for their service. Many arrived home wounded or sick. There was no medical care or veterans' pension for them, and they were left to care for themselves. 
Some of these veterans then banded together and formed organizations that would eventually band together and become known as the Veterans of Foreign Wars of the United States. After chapters were formed in Ohio, Colorado and Pennsylvania, the movement quickly gained momentum.
