England have won their first Test series in India in 28 years after centurions Jonathan Trott and Ian Bell shut the hosts out to confirm the stalemate they needed in Nagpur.
Trott (143) and Bell (116no) barely had a moment's anxiety in a stand of 208 before England declared on 352 for four in the final session, with a lead of 356 which rendered an India second innings unnecessary.
It is almost 28 years since England last won a Test series here, under David Gower and when current captain Alastair Cook was a babe in arms only weeks old.
Cook has been one of the foundations of this success, with centuries in his first three Tests after replacing Andrew Strauss as permanent captain.
But it was Trott and Bell who today ensured an achievement all the more notable after England's crushing nine-wicket defeat in the first Test in Ahmedabad.

There was much reason for personal satisfaction too - in Trott's second hundred of 2012 while Warwickshire team-mate Bell registered his first since making 235 against these same opponents at The Oval in 2010, and in a country where he had previously passed 50 just once in three tours.
Cook, Kevin Pietersen and spinners Monty Panesar and Graeme Swann had begun England's comeback in Mumbai; then the captain was at it again in Kolkata last week, when Steven Finn and in particular James Anderson's mastery of reverse-swing completed England's skills set.
It was heartening that Trott and Bell should be involved in the home straight, though, after their relative troubles in a year which has seen England lose seven of 15 Tests as well as their position at the top of the International Cricket Council rankings.
After Trott's ducks in Ahmedabad and Mumbai, he contributed significantly at Eden Gardens and here - completing the process with a typically cussed near five-hour hundred and also passing 1,000 runs after all in the past 12 months.
Bell and Trott's centuries ensured a series victory for Cook's team
England's number three reached three figures with a trademark boundary wide of mid-on off leg-spinner Piyush Chawla, and celebrated with feeling.
All around him India, minus veteran master batsman Sachin Tendulkar who was off the field with a sore neck, wore glum faces resigned to a first home series defeat in eight years.

Bell did nothing to lighten their mood either and, having had just one escape on 75 when a fierce cut at Piyush Chawla was edged and put down by Virender Sehwag at slip, reached his painstaking six-hour hundred from 293 balls.
Along the way, there had been 13 fours and a six over long-off from the bowling of Ravindra Jadeja.
Soon after that blow to bring up the 200 stand, Trott was finally gone - India's only success of the day when he was caught at leg-slip off Ravichandran Ashwin from the 310th delivery he faced.
He and Bell had joined forces at a wobbly 94 for three when Pietersen was bowled shouldering arms at Jadeja last night, and Trott's only alarm came on 106 when he missed a Chawla top-spinner but survived the lbw appeal.
England arrived here needing only a draw, but Cook was at pains beforehand to spell out the danger of settling for limited ambition with stakes so high. Cook knew then they merely needed to bat long in increasingly benign conditions to claim the prize of a historic series victory.
Thanks to their relentless fourth-wicket pair, it was never in doubt.
