Oscar-winning actress, author, and producer Lupita Nyong'o will be at the centre of a new immersive documentary film, "Warrior Women with Lupita Nyon'go", premiering on the Paramount-owned American pay-TV channel Smithsonian on Monday, 28th March.

Warrior Women follows Nyong'o as she travels across Benin to uncover the history of the Agoji, a legendary all-woman army that served the kings of the now-vanished kingdom of Dahomey from the 17th century through to the beginning of the 20th.

The all-female Amazons helped inspire the female fighting force Dora Milaje of Marvel's blockbuster film Black Panther.

"I travelled to Benin to make a documentary about the warrior women of the Dahomey Kingdom. They are arguably the world's greatest female army and helped inspire # BlackPanther's Dora Milaje. Watch #WarriorWomen when it premieres in the US on @Smithsonian_Channel on March 28 at 8pm ET/PT as part of their #WomensHistoryMonth programming", Lupita wrote on Instagram.

The documentary's official description states:

Academy Award winner Lupita Nyong'o goes on an emotional and epic journey to Benin, West Africa to uncover the extraordinary, neglected story of the little-known but highly formidable Agoji warrior women, the fearsome warriors of the Kingdom of Dahomey. For centuries, this special army force protected the rulers of one of the richest kingdoms in Africa, Dahomey, until a bitter defeat in 1892 disbanded them forever… or did it? Follow Nyong'o on this immersive and epic journey into the past to uncover the real story of the remarkable female fighters that helped inspire the Dora Milaje.

The Black Panther sequel —Black Panther: Wakanda Forever — is currently in production and stars Nyong'o. It's expected to hit cinemas this November.

Nyong'o is also set to make an appearance as a presenter at this year's Academy Awards, also known as the Oscars, on 27th March.
