As of January 2021, the World Rugby Ranking of their men's national team is 98th.
Rugby union was introduced into Eswatini by the British, who ruled the country for a number of years, sometimes indirectly, sometimes directly.
However, it was mainly played by the white population, who made little attempt to spread it to the native Swazis, meaning that the game declined when they left.
The country is nearly surrounded on all sides by South Africa, apart from one border with Mozambique.
Rugby union in South Africa is a major sport - the country has both hosted and won the Rugby World Cup - and Eswatini is saturated by South African media of various types.
