In 133 BC, the turmoil within Rome's economy proved dangerous for the Republic's stability.
With the growing economy of Rome, the gap between the rich and poor of Rome grew. With this growing gap, grew tension and turmoil within Rome. At that time stood two brothers, Tiberius and Gaius Gracchus, to stand for poor farmers of Rome, but were killed. This growing tension in the economy provoked slave revolts and military precipitation in Rome which resulted in the Fall of the Republic.

Spanish missionaries were the first European settlers in Texas, founding San Antonio in 1718. Hostile natives and isolation from other Spanish colonies kept Texas sparsely populated until following the Revolutionary War and the War of Mexican Independence, when the newly established Mexican government began to allow settlers from the U.S. to claim land there. This led to a population explosion, but dramatically reduced the percentage of the population with Mexican heritage, causing friction with the government in Mexico City. After several smaller insurrections, the Texas Revolution broke out, and the state became an independent nation in 1835. However, the newly formed Texas Republic was unable to defend itself from further incursions by Mexican troops, and eventually negotiated with the U.S. to join the union in 1845.
