Bexar was founded around 1830 and named after the mission, San Antonio de Béxar, which was the location of the Battle of the Alamo.
The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution. Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas). All but two of the Texian defenders were killed.
Santa Anna's perceived cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army. Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution.
Fort Griffin was a Cavalry fort established in the late 1860s in the northern part of West Texas to give settlers protection from Comanche and Kiowa raids.
It was named after Charles Griffin, a Civil War Union general who had commanded the Department of Texas.
The fort was officially opened in 1867. It was the starting point for many expeditions westward, and a substantial community built up around it to serve them.
Chihuahua was founded in 1709, on the intersection of the Chuviscar and Sacramento rivers. It was an important center of Spanish missionary activity.
During the Mexican-American War, Chihuahua fell to U.S. forces in 1847, after the Mexican Army was defeated at the Battle of the Sacramento River, 15 miles north of the city.
Chihuahua is now a significant industrial city, with nearly a million residents.
The town of Janos is named after the Janos people, the indigenous inhabitants of the area. The Janos did not survive contact with the Spanish and are now extinct.

Janos is now a town of around 2,700 people.

The Hoover Dam was constructed between 1931 and 1936 to form Lake Mead, the largest reservoir in the USA.
The Fort Presidio of San Diego was established in 1769, along with a Franciscan mission. After Mexico's independence, the fort was abandoned and the town grew up below.
With the end of the Mexican-American war and the great influx of Americans during the gold rush of 1848, California was admitted to the United States in 1850. San Diego was incorporated as a city in 1850.
