Eswatini's Most Common Surname Is Also Its Royal House

Dlamini is the most common surname in Eswatini. It is also the name of the family that rules the country.

Those two facts are related, and the relationship is not the one you would guess.

The kingdom

Eswatini is a small landlocked state in southern Africa, called Swaziland internationally until it changed its name officially in 2018. It is one of the few remaining absolute monarchies, with the king holding real executive power rather than a ceremonial role.

The House of Dlamini has ruled it since the eighteenth century, and the dynasty's history runs back considerably further, to the Nguni migrations that brought the group into the region.

Why so many people share it

A royal surname held by a large share of the population sounds like it needs explaining. Royal families are small.

Part of the answer is polygyny. Swazi kings historically took many wives, and Sobhuza II, who reigned for most of the twentieth century, had a very large number of children. Several generations of that produces a substantial royal lineage rather than a handful of princes.

The larger part of the answer is that Dlamini functions as a clan name rather than a family name in the European sense. Southern African Nguni naming works through isibongo, a clan identity shared by everyone affiliated to the group, which includes people connected by descent, by absorption of smaller groups, and by historical allegiance. Being a Dlamini places you within that clan. It does not claim you are the king's cousin.

This is the same distinction that makes a Korean bon-gwan work, where hundreds of separate Kim clans share one surname and very different histories.

Not the same as reaching for a crown

It is worth separating this from the pattern where a population adopts a prestigious name because the prestige is available.

Korea's Kims multiplied when the class system collapsed and families bought or forged genealogies to claim aristocratic descent. Mongolians wrote Borjigin in the surname box because the records had been destroyed and Genghis Khan's clan was the one name everybody knew.

Dlamini is not that. The clan structure was already functioning and already large, and carrying the name reflects a real affiliation within a system that had a place for it. Nobody had to invent a connection.

Where else it turns up

South Africa has more Dlaminis in absolute terms than Eswatini does, concentrated in KwaZulu-Natal and Gauteng, which reflects both the shared Nguni background of the region and the labour migration that drew Swazi workers into South African mines and cities through the twentieth century.

The surname therefore crosses a border that postdates it by a long way, in the same fashion as Diallo across the Sahel. Colonial boundaries were drawn over populations that were already distributed, and surnames tend to record the older arrangement.

A name that means belonging

Most surnames in the world tell you about an individual ancestor. A trade he worked, a place he lived, a father he had.

Dlamini tells you which group you are part of, which is a description of a living relationship rather than a fossil of one. That is why it can be shared by a king and by a substantial share of his subjects without anybody finding the arrangement strange.
