Civilization began with the Neolithic Period due to the agriculture revolution in 10,000 B.C. It allowed people to produce their own food without hunting or gathering. As a result, the new surplus of food allowed ancient cities to sprout up across the world, including Israel's present day city, Jericho. However, the new cities were now in need of a new organized government that would provide smart solutions to new found problems. More than often in organized governemnts, priets made the decision of who and what ruled over a region. That introduced the new idea that the gods from the early polytheistic religions chose the leader over a mass area thus the citizens abided by the 'Gods decision' in an attempt to please them. Apart from religion though, the increased amount of food also gave room for a variety of new jobs in a mass area. One of the more popular jobs during the Neolithic Period was to become a atrisian, which contributed new technology to society that eventually influenced future generations. Another popular occupation was becoming a merchant that allowed for the spread of new ideas across a vast region, as a result developing a more soficticated civilization. The downside of job specialization was that it created a system of social classes that ultimately limited the success of certain people while developing for the first time a cruel form of forced labor called slavery. Without this system though, the many temples and palaces that were part of the arts and architecture of a city would not be standing today, nor would the public works of a civilization such as irrigation systems, roads, bridges, and defensive walls. The most important development of a civilization though was the development of writing. It started off with a form of writing called pictograpghs that developed later into cuneiform paving the road for many new civilizations to come including the Indus, Greece, Rome, Mesopotamia, and finally Chinese civilizations. The agricultural revolution started the Neolithic Period, which started the rise of civilization.
