The Democratic Unionist Party (DUP) has confirmed that Arlene Foster, a woman who survived an IRA bombing, will share power with Sinn Fein's Martin McGuinness.
Ms Foster is set to become the DUP's new leader and also Northern Ireland's next First Minister.
Her father was injured in a targeted attack by paramilitaries when she was just 8 years-old.
Speaking to Sky News, Ms Foster said she - and the country - must move forward.
“It was a traumatic time growing up along the border in the 70s and 80s and I carry that with me. I’m just glad that my children don’t have to carry that with them. I’m very pleased to say that we’re trying to build a new Northern Ireland.”
Minister for Foreign Affairs Charlie Flanagan congratulated Ms Foster on her election, saying: “This great honour is hugely deserved and a real statement of the very high regard to which Arlene is held by her fellow party member,” he said.
“I look forward to continuing to work closely with Arlene in her new role as DUP Leader. I believe we share the same objective and determination to advance peace and stability in Northern Ireland for the benefit of all its people,” he added.
