Today is Malala's 16th birthday - declared Malala Day - and the teenager's speech to more than 500 delegates at the UN's headquarters was her first public address.
She said: 'Malala Day is not my day - today is the day of every woman, every boy and every girl who have raised their voice for their rights.
'There are hundreds of human rights activists and social workers who are not speaking for their rights but who are struggling to achieve their goal of peace, education and equality.
'Thousands of people have been killed by the terrorists and millions injured - I am just one of them.'
Speaking about the attempt on her life, she added: 'On the 9th October 2012, the Taliban shot me on the left side of my forehead and they shot friends too.
'Out of that silence came thousands of voices.
'The terrorists thought they would change my aim and stop my ambitions.
'But nothing changed except this weakness, fear and helplessness died, and strength, power and courage was born.'
Malala presented U.N. Secretary-General Ban Ki-moon with a petition signed by nearly 4 million people in support of 57 million children who are not able to go to school and demanding that world leaders fund new teachers, schools and books and end child labor, marriage and trafficking.
U.N. Special Envoy for Global Education, former British Prime Minister Gordon Brown, said Friday's event was not just a celebration of Malala's birthday and her recovery, but of her vision.
