“In a world that that can seem so aggressive, confrontational, and dangerous, you should know that you have the power to change it," Meghan rallied.
“Because whether you’re here in South Africa, at home in the UK, the US or around the world, you actually have the power within you to change things, and that begins with how you connect to others.”
She added: “If you live your life in that way, your generation will start to value each other in ways the rest of us have not yet been able to do so.”
The video was inundated with comments from fans after it was shared on the couple's Instagram account.
One Instagram user commented on the video saying: “Oh my goodness I love you Meghan! You are such an inspiration! You and Harry are doing an incredible job.”
Another wrote: “Yes. Beautiful message. Perfect words.”
“We love you Meghan! What a powerful speech,” commented another fan.
Meghan's moving speech comes just days after the couple launched court proceedings against The Mail on Sunday, along with a statement condemning the behaviour of the British tabloid press.
