On June 14, 1923, 66 groups, including the American Legion and the Daughters of the American Revolution, met in Washington, D.C. to establish a set of procedures for displaying and honoring the flag. With minor modifications in 1924, these guidelines remained the sole written doctrine regarding the American flag until the codification in 1942.
Originally enacted as Title 36, Chapter 10, United States Code by the second session of the 77th Congress, the Flag Code remained pretty much intact until the August 12, 1998 when the 105th Congress passed House Resolution 1085, Section 2(b) repealed the Flag Code as Title 36 and re-enacted it as Section 4 - 10 of Title 4, Chapter 1" ".
