A United Kingdom

"Now you will see how an empire defends itself, Mr. Khama."

"Who do you think will accept you? You belong to the whites, but they won't want you either."
[to Ruth]

"I am told that you no longer wish for me to honor my duties to serve you as your king because of the color of the wife I have chosen. South Africa's racialist disease has infected all our neighboring countries and us. Look around you! Our schools, hospitals, churches, all segregated in practice if not in law. Are we to now uphold the abomination that is apartheid in our own culture? The very same abomination that has been oppressing us for decades! Is this to the future for our Africa? We should not be fighting for segregation! We should be fighting for equality! That is where we should be focusing our minds, not on the wife I have chosen, who means you no harm! Whose only apparent crime has been to fall in love with me, and mine to fall in love with her! I cannot serve you without her by my side, but I cannot force you to accept this! Africa can never be free until all those who live in her, white and black, recognize that race must have no bearing on equality and justice! I am ready to serve you, because I love my people! I love this land! But I love my wife!"

Tshekedi Khama: "Over two decades of preparing you to be our king and this is how you face me. A white woman by your side."
Seretse Khama: "Uncle..."
Tshekedi Khama: "Are you trying to tear us apart."

"I am the government's representative in Southern Africa. The policy of apartheid, do you know this word? If you choose to marry the leader of an African nation you will be responsible for the downfall of the British Empire in Africa. Have you no shame?"
[to Ruth]

"My grandfather was a king, I am his heir. I have a responsibility to return home to my people. But I will never achieve anything worthwhile if I leave my heart here."
[kneeling in front of Ruth and holding up a ring in its box]

Ruth Williams: "You should stop here. ... My father, he wouldn't approve. I'm just two streets away. Can we do this again? I mean meet? Is that too forward of me?"
Seretse Khama: "No. No."
Ruth Williams: "What?"
Seretse Khama: "Queen Victoria. The man who negotiated for her protection of Bechuanaland, he was my grandfather. A king. I am his heir."
Ruth Williams: "Oh... I see. Thank you. Thank you for explaining, not simply disappearing. I quite understand. ... I have had a wonderful evening."
Seretse Khama: "Ruth! No, I don't think you do understand. I don't know what happened tonight, but I do know that I would hate to walk away from you here, in this moment, knowing that I wouldn't see you again."
Ruth Williams: "Well then you must. ... I mean see me again, I mean."

"Are you insane! White, British, and she's a salesman daughter!"
