According to excavations, the oldest hand-tied eastern carpet today came from the region of Iran and is roughly 2,500 years old. Around 5,000 years ago, nomadic tribe members weaved rugs from camel, sheep, and goat hair. Archaeologists have unearthed evidence of carpets dating back more than 4,000 years in Egyptian and Mesopotamian tombs. However, different parts of the world have contributed to the evolution in many ways. As a result, there can found a big diversity among the rugs coming from the different countries. The reason is the evolution scheme and the traditions and culture of them.
