The Fredonian Rebellion (December 21, 1826-January 31st, 1827) was caused by a will of Anglo settlers of Texas to alienate from its Mexican part as new immigrants were moving into their land.

Explanation:

The Fredonian Rebellion was a brief uprising of Anglo settlers in the Mexican part of Texas to step out of Mexico. The dispute was led by Haden Edwards, who was given an empresario grant to accommodate around 800 Anglo families in the area of eastern Texas, Nacogdoches. The old settlers were supposed to prove that they owned the land legally, or they were to leave; therefore, locals were indignant. Thus, Edwards and the old folks created an independent Republic of Fredonia, which encompassed some lands previously given to Edwards. However, his actions unleashed the hostility between settlers and colonists, which led the head of the Mexican government Victor Blanco to annul the Edwards’s contract.

The rebellion took place in late December of 1826 when Edwards’s supporters arrested local officials and established independence from Mexico. Nevertheless, the revolt was suppressed a year later, on January 31, when a group of over 100 Mexican troopers and around 300 of Texas residents occupied Nacogdoches to reconstruct order.

As a result, the Fredonian Rebellion made the Mexican leader toughen the military regime in the area of Nacogdoches. Therefore, some tribes had to stop their raids and sign a peace treaty. Moreover, it affected the flow of immigrants to the area of Texas. This rebellion is believed to be the start of the Texas Revolution.
