Patriarchy is a system of social organization that institutionalizes male power over women and puts male interests and values at the center of social life. Sylvia Walby explains patriarchy as “a system of interrelated social structures which allow men to exploit women.” This definition recognizes patriarchy as being institutionalized subordination and exploitation of women.

The supporters of patriarchal society justify patriarchy by attributing natural biological differences between men and women. They also focus on the influences that hormones have over biological systems. The ‘male hormone’ testosterone is responsible for masculinizing a man, whereas ‘female hormone’ estrogen feminizes a woman. In short, women are considered inferior to men intellectually and physically. According to this social system women role in society is to reproduce and serve men in the household. On the basis of recent studies and researches, it can be rightly said that there is no correlation between skull capacity and brain weight and intellectual power, yet there is still a constant struggle of gender bias in science.

Some theories also discuss patriarchy through a psychological perspective based on gender differences in psychology which are the differences in mental functions and behaviors of the sexes. Such differences are found in a variety of fields, such as mental health, cognitive abilities, personality and tendency towards aggression. Males on average are more assertive and have higher self-esteem. Females were on average higher than males in extraversion, anxiety, empathizing skills, trust, and, especially, tender-mindedness. Women also reported a more intense and more frequent experience of affect, joy, and love but also experienced more embarrassment, guilt, shame, sadness, anger, fear, and distress

Patriarchy is a multilayered, multifaceted social structure that extends across all levels such as personal, interpersonal, social, institutional, in family, in community and in government etc. The pattern of violence within personal relationships and communities grew over time because patriarchy has developed and changed over time. Virtually in practice, all societies are more or less patriarchal in nature, whereas there is no such evidence found in constitutions and laws governing such societies. The factor of patriarchy has itself integrated with the social, moral, legal, political, religious and economic organization of various cultures.

The process by which children acquire the values, motives, and behaviors viewed as appropriate for males and females within a culture is called gender typing. Children develop gender-based beliefs, largely based on gender stereotypes; which reflected in gender roles later. Children adopt a gender identity early in life and develop gender-role preferences as well.

Patriarchy has an immense impact on the lives of women in every field of life. For instance, in state/government women have less formal power and representation. In the household, they are considered a machine who produce the children and raise them. Moreover, they are more likely to being abused physically, psychologically, emotionally, socially and economically. They have fewer opportunities in professional life and also paid less. They are treated negatively in terms of sexuality. They are more misrepresented and used as a commodity in media and popular culture.

Patriarchy is a social system so, all men do not participate or experience patriarchy in the same way. Patriarchy does not necessarily mean that every man has control over every woman in every context. Various groups, most notably the feminist movement, have led efforts to change aspects of patriarchy that they believe are oppressive or inaccurate.
