One of the liberal policies of the constitution of 1824 was the creation of states in Mexico. Before that they had been provinces with a local leader but basically all was run by Mexico city. After states were created, they were given some manner of home rule, like in the USA. Texas was a joint state with Coahuila.

All government paperwork from Texas had to be taken to Saltillo for approval. Land grants and surveys had to be recorded there. All manner of official paperwork had to be sent and recorded there. In return permission for all manner of public works, etc had to be put on hold until the governor gave his approval. Major stumbling block. The alcaldes and empresarios saw the need for Texas being its own state w/o having to sent stuff all way to Saltillo and wait months for a reply.

Under mexican law Texas did not have the necessary population numbers to be a mexican state. (Ok anyone see where this is going?). Stephen Austin was thrown in prison in Mexico City ( remember he’s a Mexican citizen, following Mexican law) while trying to negotiate for Texas Statehood.

"Come, shall we go and kill us venison?
And yet it irks me the poor dappled fools,
Being native burghers of this desert city,
Should in their own confines with forked heads
Have their round haunches gored."
