Born in a suburb of Chicago in 1993, Charlie Kirk got started early in conservative politics, first penning an essay for right-wing Breitbart News at the age of 18, accusing schools of spreading "propaganda" and "indoctrination".
He caught the eye of Bill Montgomery, a retired businessman and Tea Party activist more than 50 years his senior, who took Kirk under his wing.
In 2012 – around the midpoint of Barack Obama's presidency – the pair founded Turning Point USA, a group which focused on conservative activism on college campuses, spreading rapidly along with Kirk's social media following.
The group tapped into online media and spread a slickly packaged style of conservatism to young people. It won him a speaking place, aged 22, at the 2016 Republican National Convention.
Kirk's political views drifted rightward over time. He was against gay marriage and abortion, argued for Christian nationalism and was highly critical of Islam, and famously said that gun deaths were "worth it" for the right to own firearms. He was also an opponent of diversity programmes and spread falsehoods about topics such as Covid vaccines and voting fraud.
Above all, he was loyal to Trump.
