How is the name Swaziland connected to King Mswati II?

The name Swaziland was derived from Mswati II, a 19th-century monarch who is considered one of the greatest Dlamini-Ngwane kings.1

Mswati II ruled from 1840 to 1868 and was instrumental in expanding the kingdom's territory through conquest and the assimilation of various clans. Because of his significant role as a nation builder and his reputation as a "greatest fighting king," the Swazi people took their name from him, which subsequently became the basis for the country's former name, Swaziland.123

In April 2018, the current monarch, King Mswati III, officially changed the country's name from the Kingdom of Swaziland to the Kingdom of Eswatini.453
