The correct answer to this open question is the following.
The local government of Spanish Texas changed and evolved into the county government system used in Texas today in the following way.
It was in 1845 when Texas joined the United States. United States citizens, values, and ideas had influenced Texas for quite a time and the form of government of the state was shaped under those important influences, instead of leaving the presence of Hispanic or Mexican traditions. Although Texas had been a territory of México, many things happened in the settling of that territory, and conflicts arose. Finally, in 1936, a strong presence of American people shaped the Constitution of the Republic of Texas.
