Although it is an old custom, not In fact, it is being debated in Botswana. everyone in African cultures is happy with it. Many people, including many women, support payment of lobola. They explain that in Tswana culture, a marriage means joining a family, not just marrying an individual. The idea of marrying into a family is very African. just the man.Through marriage, the young woman's family loses their daughter as she then becomes a part of her husband's family. Lobola is a way to show thanks. It is a form of generosity in African culture. In its traditional form, they also explain, the groom's family gave cattle to the bride's family.

A woman does not get married to A man only had to pay what he could afford if he had no cattle, he could give something else, even the smallest form of payment.

She did the cooking When a family lost that child through marriage, it demanded payment. Today, they think that lobola has changed into a useless tradition. In this custom, a man is buying the right to control a woman. They say women are individuals with rights. In today's world, parents do not have to be paid for a bride because their male and female children are equal. They all work and make contributions to the household. They believe that paying lobola makes it seem like a man is buying a pair of shoes or a bicycle, instead of getting married. They also argue that it is often a financial burden for couples. It is too difficult for many people to pay the price asked. So, is lobola a rich tradition, bringing families together? Or is it an ugly custom of buying women? This debate continues in Botswana, as does the custom.
