It is believed that weaving was started somewhere in Asia but it is not exactly clear where. Persian nomads brought the art of weaving to Turkey in the 11th century. They began weaving carpets by using Goat hair. They used very simple techniques similar to that of braiding. Due to harsh environmental conditions they lived in the idea became very popular and the techniques more sophisticated. Over time the rugs were used for many purposes such as blankets and beds. The technique of piling became popular when it was discovered that it made a comfortable bed. Pre-Ottoman weaving patterns contained images of pagan deities, however during the Ottoman rule these images changed. The Ottomans continued the art of weaving by opening exclusive workshops and using carpets to decorate palaces and homes. They also used them as political tools to form and establish friendships with European country's where the rugs became very valuable. In those days only kings and noblemen could afford such luxuries and many started private collections. As changed occurred politically those private collections were opened to the public and the rugs became very sought after by the general population of Europe. It was not until the 19th century however that additional workshops were opened to increase production of the now so well sought after carpets. Because weaving had been operated and maintained by Ottoman royalty for so long the techniques, quality and design has been so well preserved. Today, these fine rugs are woven in more than 750 villages and tribal (nomadic) areas.
