The Spanish had several advantages when conquering Central American Indian tribes, including micro patriotism, the use of metal weapons, and alliances with other native groups. However, the native tribes still greatly outnumbered the Spanish forces, with an estimated 250 Spaniards facing 5,000 Indians. Over time, the population imbalance increased further in favor of the native tribes. Both the Spanish and their native allies played important roles in the conquest, but the native groups suffered fewer casualties and appeared more united than the Spanish forces.
