President Taft signing the proclamation establishing Arizona as a state on February 14, 1912
establishing Arizona as a state
New Mexico became a state on January 6, 1912, and Arizona became a state on February 14, 1912. Thus, two stars were added to our flag in 1912 on July 4th signifying that two new states were added to the 46-star flag then. That flag lasted exactly 47 years from July 4, 1912, through July 4, 1959.
