Being the smallest social institution, family has attracted the attention of social thinkers due to the special significant place it occupies. On the one hand, the mutual effect between family and other sections of society, and on the other hand, its survival throughout ages and centuries have driven many thinkers to study it using different approaches. Apart from the religious, ethical, philosophical and legal approaches dominant in the past, there has been a growth of historical, anthropological, psychological and social approaches to family since the 19th century.
