Following on from their opening day victory over Fulham, a battling display from Phil Brown's side at Ewood Park handed the Tigers an impressive fourth point of their debut season in the Premier League
Jason Roberts gave Rovers the lead towards the end of the first half, only for Hull midfielder Richard Garcia to equalise just two minutes later in a match that saw Stuart Attwell become the youngest referee in Premier League history at the age of 25.
The young official barely put a foot wrong, letting the game flow wherever possible in a confident debut that will have endeared him both to fans of football and his bosses at the Football Association.
Roberts swooped after 38 minutes, the hard-working striker running onto Andre Ooijer's threaded through ball to keep his cool in a one-on-one situation with keeper Boaz Myhill and slot home.
It was nothing less than Blackburn deserved, the hosts having enjoyed the better of the opening 45 minutes. And they would have gone in at half-time in the lead had Hull not showed remarkable character - the kind which will stand the top flight newcomers in good stead this season - to hit back almost straight away.
Australia international Garcia got on the end of a deep Craig Fagan cross to loop a header back across the face of goal, leaving Rovers keeper Paul Robinson helpless as the ball crept just inside the far post.
Earlier, Hull had gone mighty close to taking the lead but Craig Fagan inexplicably stopped his run into the box just as Dean Marney played a teasing ball into the Rovers' box that was crying out for a touch to divert it across the goal line.
Blackburn had chances of their own, Morten Gamst Pedersen going closest on 22 minutes with a lovely half-volley with the outside of his left boot that drifted inches wide of the angle of post and bar.
The second half started slowly as Hull's ultimately successful attempts to take the sting out of Blackburn's game created a dull 45 minutes - in stark contrast to the entertaining first period.
Aside from a loud Rovers penalty shout - when Roque Santa Cruz saw a powerful shot strike Michael Turner on the hand - the second half rarely produced anything capable of rousing the crowd.
Santa Cruz fired over the bar before the closing moments of the game finally provided some excitement, Hull substitute Caleb Folan going close to adding to his opening day goal before Sam Ricketts was presented with a chance to win all three points.
The visitors had to settle for just one in the end but having displayed their defensive qualities in a tough-looking fixture away from home, the newcomers are looking very much a Premier League side.
