Furthermore, the powerful monsoons that the civilization experienced had an even greater contribution to the unpredictability of the harvests. Monsoons are seasonal winds that dominate a regions climate and greatly affected the farming system. The dry winds usually came in October May and the wet winds usually came in June September. As has been said, the geography of the Indus River valley, such as the mountains, river, and monsoons, had a great impact on the civilizations level of prosperity, whether it be positive or negative.
Due to the Indus ability to develop and adapt to its geography, many characteristics of the civilization made it unique to others, such as its city structure and architecture, strong central government, and artesian items. Because the civilization was isolated, it gave the Indus people time to focus on building well-planned cities instead of worrying about invasions and warfare. The Indus people mapped out cities based on a grid system, which included a citadel for the priests, nobles, and leaders. Early Indus engineers also included a complex and sophisticated plumbing system within their cities to removes waste from homes and to supply clean water. Some wealthy families even had a private well. In order to build these public works, it was necessary for the Indus people to have a strong central government. This government system was based on the polytheistic Indus religion. It also collected taxes in order to fund the construction of cities and the public works within it. The Indus people also focused greatly on the artistic aspects of life. Artisans spent a lot of time creating toys, jewelry, paintings, and other works of art to trade for necessary resources. They greatly valued art in their culture, and were likewise very talented at it. The Indus civilization developed complexly in the form of architecture, government, and art due to their ability to grow freely within their isolated area.
