2 Laredo was known as the Republic of the Rio Grande
Founded in 1755, Laredo was its own independent country together with three Mexican states for a short period of time in 1840. Laredo eventually grew from a small village into the capital city of the independent Republic of the Rio Grande. Eventually joining again with Mexico, Laredo was signed over to the United States after the Mexican-American War in 1848. Boycotting the move into the United States, Mexican residents moved across the Rio Grande back into Mexican territory, founding Nuevo Laredo—the new town.
3. Laredo is the only city in Texas to fly under seven flags
While most Texans know about the six flags that fly over Texas, representing the six countries that had sovereignty over all or parts of the state at any given time, Laredo is the only city to have seven. Why seven? The seventh flag, joined with the other six representing Spain, France, Mexico, the Republic of Texas, the Confederate States of America and the United States of America, represents the short-lived Republic of the Rio Grande.
