Why or why not?

The statement that traditional African marriage is an advantage for men only, not women, is a generalization that may not apply to all situations or cultures within Africa. It is important to recognize that Africa is a diverse continent with a multitude of cultural practices, including various forms of marriage.

In some traditional African societies, marriage may indeed have advantages for men in terms of power dynamics, inheritance rights, and social status. This can be attributed to patriarchal structures and gender inequalities that exist in some communities. Women may face discriminatory practices such as bride price, where they are seen as commodities to be bought and sold, or they may be subject to limited decision-making power within the family unit.

However, it is crucial to note that not all traditional African marriages follow the same pattern, and there are diverse cultural norms and practices across the continent. In many African cultures, marriage is a social contract that also provides benefits for women. For instance, marriage can provide economic security, social support, and a sense of belonging within the community. Women may also gain access to resources and support networks through their marital ties.

To fully understand the advantages and disadvantages of traditional African marriage for both men and women, it is necessary to look at specific cultural contexts and individual experiences. It is important to avoid generalizations and acknowledge the complexity and diversity of African traditions.
