During the American Revolution, the Grand Union Flag, also called the Continental Colors, was created to represent the colonies. It featured 13 alternating red and white stripes (symbolizing the original colonies), but instead of stars in the upper left corner like we see today, it displayed the Union Jack.

1777

In 1777, following the Declaration of Independence, the Continental Congress adopted the first official flag of the United States. It featured 13 alternating red and white stripes, which still honor the original colonies today. Replacing the Union Jack, it introduced a new element that would be key for the rest of its history: 13 white stars set in a blue field, or canton, arranged in a circle to symbolize equality and unity among the states.

1795

It wasn’t until 1795 that the flag changed again, when two more stars and two additional stripes were added to represent the recently admitted states of Vermont (1791) and Kentucky (1792). This version was the only US flag to feature more than 13 stripes and later became known as "The Star-Spangled Banner", since it was the very flag that inspired Francis Scott Key to write the poem that would later be the lyrics of the national anthem.

1818

In 1818, the flag’s design changed once again. The 15 stripes were reduced back to 13 to permanently honor the original colonies. Five new states had joined the Union, bringing the total number of stars to 20. These stars were sometimes arranged in straight rows and other times in the shape of a large star, which earned this version the nickname "The Great Star Flag."

1912

Each new state joining the Union meant one more star on the flag. In 1912, when New Mexico and Arizona were added, the number of states reached 48, so their stars also took their place. That year, President Taft issued an executive order setting the official proportions of the flag and specifying that the stars should be arranged in six horizontal rows of eight.

1960

The most recent design change came in 1960. After Alaska and Hawaii joined the Union in 1959, two more stars were added, bringing the total to 50. They were arranged in nine alternating rows of six and five stars, like the official flags you see displayed across the country today.

Flag time

Beyond its official design, the US flag follows a set of protocols established over the years. One key rule specifies the time to display it: generally, the flag should be flown from sunrise to sunset. If displayed at night, it must be properly illuminated.

8

Weather conditions

The flag code doesn’t just set the time of day; it also indicates the proper weather conditions for display. According to the protocol, the flag should not be flown in bad weather, such as rain, snow, or storms, unless it’s an all-weather flag designed for such conditions.

Position

Of course, the flag must always have the blue canton in the upper left corner. But there are more rules for its position. When flown with other symbols, such as state flags, the national flag must be in the center and slightly higher. Additionally, if it needs to be lowered from the flagpole, the flag must never touch the ground.

10

Don'ts

If you need to handle the flag, it’s important to know the proper way. But it's also crucial to know what not to do. Some of the key "don'ts" include never letting it touch the ground, avoiding creasing it, not writing or drawing on it, and one that might surprise many: don’t use it as clothing or decoration.
