Leo Varadkar has been named one of the world's 100 most influential people by Time magazine.
The Taoiseach made the cover of the publication last July and is included as a symbol of how far Ireland has come in the past 25 years.
He joins Donald Trump and Meghan Markle on the list, as well as 14-year-old Stranger Things Actress, Millie Bobby Brown.
Philip Ryan, co-author of a new book 'Leo Varadkar – a Very Modern Taoiseach' along with Niall O’Connor, wrote the entry on the Taoiseach.
In a piece about Mr Varadkar for the magazine, journalist Philip Ryan says: "When Ireland finally decriminalized homosexuality in 1993, the Catholic Church still had a firm grip on the state's affairs.
"Divorce was illegal, and its abortion laws were deeply entrenched as some of the most conservative in the West.
"Twenty-five years on, Ireland is a very different place—symbolized by the rise of its new leader, Leo Varadkar."
He adds: "The openly gay son of an Indian immigrant, Varadkar decided to come out publicly in the run-up to the world's first marriage-equality referendum.
Today the once anti-abortion politician is campaigning to significantly liberalize the country’s abortion laws.
"The country’s youngest-ever Taoiseach will be judged on how he guides his nation through these challenges."
It also touches on Mr Varadkar being at the centre of EU negotiations on Brexit - while also facing "a major housing and homelessness crisis".
Former Taoiseach Enda Kenny also appeared on a Time magazine cover back in 2012 - while former President Mary Robinson was named as one of its most influential people back in 2005.
