During the 15 th century, the Incas and the Mexicans were able to expand and create large empires in a relatively short time. The Incas Empire occupied what is the modern day the southern frontier of Colombia stretching southward along the coast and highlands of Ecuador and Peru, the highland of Bolivia north western Argentina and Central Chile. The empire comprised of a single group ruled from capital Cuzco (Conrad and Demarest 84). The empire’s culture in its initial stages developed from interactions with other local antecedents as learnt through ethno history and archaeology. The Aztec empire occupied the modern day Mexico and was formed by a collection of tribes after the collapse of the Toltec civilization. It was created in the 1400’s with the capital Tenchtitlan standing where the modern day Mexico City stands today and has attained an advanced level of artistic, economic and intellectual progress. The empire was established from a tiny island which was the only dry place surrounded by marshes and with powerful neighbors and flourished to be a strong and expansive empire (Crosby 13). Modern studies of the Incas beliefs describe the upper pantheon of Incas beliefs as divine complex, multifaceted sky God composed of numerous individual aspects. This divine complex was interpreted into many aspects of sub complexes according to the needs of the people. In the imperialist Incas, there was a state religion which gave importance to three sub complexes of the sky God (Conrad and Demarest 101), Virococha, the universal creator; the sun god Inti; and the weather deity Illapa which were distinct deities. The most solemn form of worship for Incas was by fire which was employed on very serious occasions and therefore fire diviners were greatly feared and respected and were also known as ‘consulters of the dead’. In the fourteenth century, the Incas came to believe of a divine being Inti who protected their state, and from where their rulers came from. This led to formation of a cult which served the interests of the rulers and gave Incas a sense of national identity. The Aztec mythology centered on the worship of forces of nature represented by the earth, sun and rain gods which were offered human sacrifices. The sacrifices included human body parts like the heart and blood from just killed victims. The need for human sacrifices was a major reason why the Aztec conquered new territories and people In the fourteenth century, small groups and tribes began to make military alliances and this intensified previously minor misunderstandings. The Incas adapted to these circumstances well because they had leaders who were skillful warriors and shrewd politicians experienced through inter village raiding and rule by sinchi’s skills practices. This led to emergence of great leaders capable of defending the Incas in times of heightened competition and able to conquer, occupy and expand the empire. Divine patronage of the Incas religion, where the rulers were believed to descend from the Inti sun god, gave them a sense of national identity where they felt set apart from their neighbors and united them both politically and military. This gave them the drive to survive in competitive circumstances (Conrad and Demarest 110). Another aspect which led to the expansion of the em
