Investigating Ethnic Identity and national identity in Afghanistan (in Afghan universities)

National identity is a mental concept that represents belonging to a particular national group. National identity is accompanied by a complex set of conditions and feelings that indicate an individual's attitude towards his or her own group and other groups.The issue of national identity in Afghanistan has always been a very sensitive political and cultural issue because linguistic, ethnic, cultural, and religious differences in Afghanistan and ethnic and cultural similarities with the peoples of neighboring countries, as well as war, conflict, and destruction in Afghanistan, have prevented national identity from being fully formed in this country.The aim of this study was to examine the social and cultural factors related to the national identity of Kabul education students; In this study, social and cultural theories such as Giddens and Stryker were used to explain the national identity of students in three ethnic groups (Pashtun, Hazara, and Tajik).We used the survey method to collect data; the sample size was 372 people, which was taken using the systematic random sampling method; data analysis was also carried out using SPSS software; the findings of this study show that there is a significant and positive relationship between the variables of ethnic, religious, global identity and social capital, lifestyle and participation in national identity; In addition, based on multivariate regression, the variables of social and participatory lifestyle, religious identity, social capital, and gender explain 10.7 percent of the changes in the dependent variable.
