owed four months of back pay. The royalist cause's most important allies were the landed nobility, many of whom threw their allegiance behind King Charles after seeing the comuneros support peasant rebellions against them. They offered a powerful combination of militarily experienced commanders, disciplined troops, and expensive horse cavalry. However, they were also unreliable. Many nobles' first goal was to protect their own lands, and crushing the rebellion but losing their own holdings would be a loss. As such, the Regents often had difficulty rallying the noble forces to make a combined army. After the victory at Toredesillas, for example, many royal guards were dismissed due to lack of funds to pay them, and many noble-controlled armies returned to their home areas, greatly endangering the defense of Tordesillas and preventing any new offense. After the burning of Medina del Campo, the royalist cause had to struggle with negative perceptions from the populace. As such, the royalists took considerably greater precautions than the comuneros to avoid enraging the countryside. For most battles, the royalist troops were forbidden from looting captured cities for income. This caused considerable dissatisfaction among the ranks and exacerbated the problem of the low pay for the soldiers, but also saved the royalist cause from even further distaste from the populace. The commanders of the royal army were also brave enough to dismiss unnecessary additional troops. Untrained peasant levies were unlikely to be very effective on the battlefield, but would be additional bellies to feed and could easily offend the countryside with undisciplined looting. Loyalty was an additional concern that the royalist cause faced. New recruits from the cities of the Meseta were unlikely to be terribly loyal, and might even leak information. As a result, the royalist armies generally used poor Galicians from the North for additional troops.

A variety of reasons exist for this. Among the nobles, there was a great investment in the project of Hispanicizing the recently conquered Granada and its Moriscos. It was crucial for the government to act unified to maintain stability; if some cities of Andalusia were to join the Comunidades and others not, a civil war among the Spanish Christians would invite
