The Spanish were to fare less well against the less centralised societies of southern Chile, however, particularly once local forces began to adapt to, or actually adopt similar military technologies. Although Pedro de Valdivia was able to successfully invade Chile in 1540, the first great rebellion of the Arauco wars was to begin only 1553 later, marking the beginning of a conflict that would last until the 19th century. Spanish forces, operating at huge distances from their European or even Caribbean centres of power, were frequently available in small numbers; Valdivia had great difficulty in recruiting even the 150 Spanish soldiers he used to invade Chile, and the frequent reversals during the Arauco wars led to losses that often took several years to replace. As time progressed, the advantages of the Spanish began to increasingly centre on their access to early modern firearms, especially the musket, rather than the technologies that had won them their early successes.
