In the domain of rural and nomadic carpet weaving of Fars Province, there are various common patterns and designs. One of these famous patterns is called Yeksar Nazem which, in the past, solely belonged to Qashqai and Kashkouli tribes but, at present, is popular in other areas of Fars Province as well. The main feature of this pattern is its general structure and elements which have been skeptically categorized by researchers in different contextual forms. This pattern has been studied by some researchers among Mehrabi carpets and Darghahi pattern which opens to a garden. The aim of this research is to study the main features of Yeksar Nazem pattern and to identify its main elements in Fars Province carpets so that its pattern of change from Qajar to the present period can be obtained. This study is descriptive-analytic which qualitatively analyzes the main elements of Yeksar Nazem carpets of Fars Province in two groups of old and new carpets.  The method of data collection is field and library study. 50 samples of Yeksar Nazem carpets were considered as the main data pool, out of which, and based on the available frequencies, 10 carpets were purposefully (non-randomly) selected as old carper samples and 10 carpets as new ones. The results indicate that the structural form of the pattern and the main features of Yeksar Nazem carpets have observed changes in the structure and the attitude towards the content of this pattern from Qajar era to the contemporary period. This pattern has recently appeared among new carpets with diversity in overall composition and simplicity in the form of elements. Its weaving place has also been extended from a particular geographical area to wider areas in Fars Province.
