Why the Spanish Franciscans kept the fruitless missionary work in Texas in the late 17th and 18th Centuries?

Outta Touch is wrong, no offense meaning, the Viceroys of new Spain would just build forts and missions to secure the area of East Texas fearing the intrusion of the French from Louisiana, who had strong trading with the Caddos and in less amount with the Karankawas.

There are HUNDREDS of BOOKS about the Spanish in the Southwest and the MISSIONS in the Southwest.. and I suggest you read a few before you make conclusions.

You don't even seem to know that the FIRST MISSIONARIES in Texas were JESUIT and not FRANCISCAN and I will let YOU find out why the POPE threw the Jebbies out of Texas.

It was the RELIGION that actually brought down the Spanish because the FRENCH were only interested in TRADING with the Indians.. and the SPANISH wanted to CHRISTIANIZE the indians and were will to save their souls at the point of a BAYONETS or the end of a ROPE.

The missions WERE a success in that the whole purpose of a Missions was to COLLECTIVIZE all the Indians in a given area and use their labor to support the Spanish Incursion into the Southwest. The missions only FAILED because the WEATHER CHANGED and the DROUGHT that lasted for over 200 YEARS resulted in food shortages and civil strife.. when the Indians saw that GOD and GEEUS were no Better at fulfilling THEIR needs than the OLD GODS of the Indians.. they chased the Spanish back to Mexico
