A photograph of DUP leader Ian Paisley and Gerry Adams of Sinn Fein at the same table after their power-sharing deal graces many of the front pages.
But, as if to highlight how far they have come, the Times, pictures the two men separately during the Troubles, each bearing coffins of men killed.
The Independent views the deal as a triumph of both style and substance.
The Daily Mirror describes their "simple hour-long meeting" as "an extraordinary act of reconciliation".
Dr Yes
The Sun says Gerry Adams deserves credit for accepting violence will never deliver harmony.
But in its editorial, the paper argues that Dr Ian Paisley has emerged as the architect of peace, forcing Republican hardmen to lay down their guns.
According to the Guardian, it was the day Dr No said "yes".
But the Daily Telegraph's Ruth Dudley Edwards reckons the men have primacy within their respective tribes and will now work out a way of splitting power.
Blair succession
The Financial Times suggests Tony Blair is likely to trumpet Northern Ireland as one of the big achievements and announce his departure in May.
The Times says Gordon Brown will deter any challengers to him taking over as PM by demonstrating the support he has.
But the Daily Telegraph reckons poll falls for Labour could see Environment Secretary David Miliband challenge.
The Daily Mail, however, says he is being lined up for a senior role in return for a pledge not to stand.
Woolmer 'suspect'
The Daily Star and the Daily Mirror both lead with a development in the murder of Pakistan cricket coach Bob Woolmer in Jamaica.
Under the headline "British suspect on the run", the Star reports police are hunting a London-based Pakistan cricket fan and two of his associates.
The Mirror says the men were "hangers on" who ran errands for their heroes before the team's loss to Ireland.
The paper says officers want to eliminate the men from their inquiries.
