Why is Texas called the Lone Star State?

The Lone Star State: Perhaps one of the most recognized nicknames of any state, "The Lone Star State" comes from the symbolism of the star on the 1836 flag of the republic, the "National Standard of Texas." The single golden star on a blue background signified Texas as an independent republic and was a reminder of the state's struggle for independence from Mexico. The "Lone Star" can be found on the Texas State Flag and on the Texas State Seal today.

"A single star was part of the Long Expedition (1819), Austin Colony (1821) and several flags of the early Republic of Texas. Some say that the star represented the wish of many Texans to achieve statehood in the United States. Others say it originally represented Texas as the lone state of Mexico which was attempting to uphold its rights under the Mexican Constitution of 1824. At least one "lone star" flag was flown during the Battle of Concepcion and the Siege of Bexar (1835). Joanna Troutman's flag with a single blue star was raised over Velasco on January 8, 1836. Another flag with a single star was raised at the Alamo (1836) according to a journal entry by David Crockett. One carried by General Sam Houston's Texian army (which defeated Mexican General Santa Anna at the Battle of San Jacinto ) may have been captured and taken to Mexico. Another "lone star" flag, similar to the current one but with the red stripe above the white, was also captured the following year (1837) and returned to Mexico. The "David G. Burnet" flag, of "an azure ground" (blue background) "with a large golden star central" was adopted by the Congress of the Republic of Texas in December of 1836. It continued in use as a battle flag after being superseded in January of 1839. The 1839 design has been used to symbolize the Republic and the “Lone Star State” ever since."

Cause we truly believe that here in Texas we stand Alone above the rest. Like the Lone Star of the West! ( Can't you just hear those trumpets playing in the back ground)

Because it is the only state in the country that was once it's own country.
