This week I journeyed today to Baltimore, Maryland, via the Niles’ Weekly Register of May 9, 1818 . I found the announcement of “An act to establish the flag of the United States. Be it enacted by the senate and house of representatives of the United States of America in congress assembled, that from and after the fourth day of July next the flag of the United States be thirteen horizontal stripes, alternate red and white: that the union be twenty stars, white in a blue field. Sect. 2. And be it further enacted, That, on the admission of every new state into the union, one star be added to the union of the flag; and that such addition take effect on the fourth day of July then next succeeding such admission.” This was approved on April 4, 1818 and signed by President James Monroe.
Fly them high and proud!
