After the conquests by Pizarro and Cortes, they allocated lands to their troops by their own authority. But soon the Spanish monarchy extended its control and sent over lawyers, tax collectors, bureaucrats, and royal officials who implemented royal policy and administration. Established two main centers of authority Mexico (New Spain) and Peru (New Castile), each governed by a viceroy loyal to Spain, who were reviewed by Spanish courts known as audiencias, who gave any negative reviews straight to the Spanish king. But was not a thorough affair: often took two years for a response of correspondence to take place, and even then it wasn't a direct order, and limited transportation limited the viceroys power in the Americas, and other local power fell to the audiencias or town councils. Even though they got income from ag. prod., they preferred to live in cities, and established many- Mexico City, Lima, Buenos Aires, and St. Augustine were some of the earliest.
