Because of the trade restrictions and low tax rates imposed by Spain on the Philippines, the islands wasn’t generating enough income to maintain the colony. So Nueva España covers the deficit.
There was a Special Judicial court, the Residencia, that investigates the performance of the outgoing Ph Governor Generals to ascertain wether or not they had faithfully and honestly fulfilled their duties. This practice was discontinued by the 1800′s. (It is also impt to note that, although this was implemented with good intentions, it kinda backfired and encouraged more corruption)
There were a lot of missionaries sent to Philippines that watched over the natives and made sure they were not abused by the government officials. Though around this time, they were probably more lovable than those in the late 1800′s.
As previously stated [x], New Spain was mostly in charge of military defense.
A European author (I forgot who 0w0;;) said that Manila, the capital, was very lively when the Galleon ships return from Nueva España, it was practically a fiesta. It was for an obvious reasons, those ships bring a lot of money to the islands.
After the ships leave, it gets boring again and everyone is broke from too much partying and gambling.
I’ve mentioned before that I haven’t read any articles during Nueva España’s time, but it seems that one of the biggest problem in the Ph during the Spanish period was pirates.
I’ve noticed too that the usual solution when there is civil unrest was to send in the Catholic missionaries to appease the natives. I guess using religion to take advantage of a superstitious nation was a much better option than using violence.
Except in major cities, the priest is often the only European allowed to live in local communities. They have taken on a patriarchal role and the natives listen to and believe in everything they say (EVERYTHING), making them indispensable in the colony.
