What does the addition of the last star on the flag symbolize?

The addition of the last star on the flag symbolizes the admission of Hawaii as a state. This occurred on July 4, 1960, when Hawaii officially became the 50th state of the United States. The stars on the American flag represent the individual states, and the last star signifies the completion of the current flag design, which captures the full representation of the country as it exists today. This change reflects the historical and political significance of Hawaii’s statehood, marking an important moment in U.S. history as it expanded its territory and influence over the Pacific region. The other options relate to different historical events, but none represent the specific context of Hawaii's statehood on the flag.
