Michelle Obama, the wife of US Democratic party presidential nominee Barack Obama, has spoken at the opening of the party convention in Denver, Colorado. Here are some of the key moments from her speech.
I come here as a wife who loves my husband and believes he will be an extraordinary president. And I come here as a mom, as a mom whose girls are the heart of my heart and the centre of my world. They're the first things I think about when I wake up in the morning and the last thing I think about before I go to bed at night. Their future, and all our children's future is my stake in this election.
Barack and I were raised with so many of the same values - that you work hard for what you want in life, that your word is your bond and you do what you say you are going to do, that you treat people with dignity and respect, even if you do not know them, and even if you do not agree with them.
And Barack and I set out to build lives guided by these values, and pass them on to the next generation.
[Barack] talked about "the world as it is" and "the world as it should be." And he said that all too often, we accept the distance between the two, and settle for the world as it is - even when it does not reflect our values and aspirations.
But he reminded us that we know what our world should look like. We know what fairness and justice and opportunity look like. And he urged us to believe in ourselves, to find the strength within ourselves to strive for the world as it should be. And isn't that the great American story?
All of us driven by a simple belief that the world as it is just won't do, that we have an obligation to fight for the world as it should be.
That is the thread that connects our hearts. That is the thread that runs through my journey and Barack's journey and so many other improbable journeys that have brought us here tonight, where the current of history meets this new tide of hope. That is why I love this country
He will achieve these goals the same way he always has - by bringing us together and reminding us how much we share and how alike we really are. You see, Barack does not care where you are from, or what your background is, or what party - if any - you belong to.
That is not how he sees the world. He knows that thread that connects us - our belief in America's promise, our commitment to our children's future - is strong enough to hold us together as one nation even when we disagree.
I stand here today at the crosscurrents of that history - knowing that my piece of the American dream is a blessing hard won by those who came before me. All of them driven by the same conviction that drove my dad to get up an hour early each day to painstakingly dress himself for work. The same conviction that drives the men and women I've met all across this country...
People like Hillary Clinton, who put those 18 million cracks [a reference to her vote total in the primaries] in the glass ceiling, so that our daughters - and sons - can dream a little bigger and aim a little higher.
