Donald Trump has said "we will make America great again" as he formally accepted his nomination as the Republican candidate for US president.
To chants of 'USA, USA', he said he "humbly and gratefully" accepted the nomination before setting out his pledge to increase stability, security and crack down on illegal immigration.
In a 75-minute speech he said: "I am your voice.
"We will make America strong again, we will make America proud again, we will make America safe again and we will make America great again."
Taking a swipe at his Democrat opponent Hillary Clinton, he said that her "bad instincts" as Secretary of State are to blame for "many of the disasters unfolding today".
He added he is "determined to deliver a better life for the people all across this nation that have been neglected, ignored, and abandoned."
And he pledged to reduce and simplify tax, cut down on regulation, create more jobs, cut Obama health care and "rebuild our military".
He said that homicides had risen by 17% in the USA's biggest cities which he said was the largest increase in 25 years.
He said that "uncontrolled immigration" is responsible for "mass lawlessness".
Referring to the Nice attack, he vowed to stop the threat of "Islamic terrorism".
Trump also used his speech to refer to Nato following his comments that questioned whether he would automatically defend allies in the event they are attacked.
Red, white and blue balloons were released to mark the end of the convention as Trump was joined on stage by his family and his VP running mate Mike Pence.
