CLEVELAND, Ohio - Dozens of versions of the Stars and Stripes, and at least one variation without stars before 1777, have flown as the American flag.
With Thursday being the 102nd national Flag Day, we look back at some of the changes over the years with a gallery of flags below.
The same 50-star flag has flown since 1960, soon after Hawaii became the nation's 50th state.
But earlier versions not only had fewer stars - and briefly more stripes - they also included different arrangements of the stars.
President William Howard Taft, a Cincinnati native, by order in 1912 set the proportions for the flag, as well as the positioning of the stars.
As for Flag Day itself, President Woodrow Wilson proclaimed June 14 Flag Day in 1916. Before then, some states and local communities celebrated Flag Day.

No stars - 1775 to 1777
According to the Encyclopedia Britannica and other sources, the unofficial national flag was raised at the direction of Gen. George Washington on Jan. 1, 1776.
The flag had 13 horizontal stripes and, in the upper left, resembled the British Union Flag. This flag, or flags with similar designs, flew over forts and naval vessels as the flag of the Continental Army.

13-stars - 1777 to 1795
The Flag Resolution of June 14, 1777 "resolved that the flag of the United States be made of thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new Constellation," according to history published by the Smithsonian.
Thirteen, of course, represented the 13 original states: Delaware, Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts, Maryland, South Carolina, New Hampshire, Virginia, New York, North Carolina and Rhode Island.

15 stars - 1795 to 1818
The addition of Vermont in 1791 and Kentucky in 1792 led to the 15-star, 15-stripe flag. But this was the only time the number of stripes expanded because of the addition of states.
A change was made on April 4, 1818, that both reduced the number of stripes and set any change to occur on July 4, following the addition of states.
This set the number of stripes at 13. And there would be no change in the number of stars until the first Independence Day after states were added.
