Williams had been stuck on 21 Grand Slams since winning last year's Wimbledon, but the American star ended that frustrating barren spell to retain the title and draw level with Steffi Graf's Open era record.

Serena was pushed hard by Kerber in a high-quality clash lasting 81 minutes on Centre Court, but the German fourth seed eventually crumbled under a barrage of 39 winners and 13 aces from the defending champion.

"It's a great feeling to be here. Angelique brings out great tennis in me," said Serena.

"Number 22 is awesome. Centre Court feels like home." Kerber said the American was a great champion.

"Serena you deserve it, you are a great champion and great person. We played a great match," said Kerber.

"It's an honour to play on Centre Court and a great feeling."

Having avenged her shock loss against Kerber in the Australian Open final in January, Williams was wreathed in smiles as she paraded the Venus Rosewater Dish around Centre Court after collecting a cheque for £2 million (USD 2.5 million, 2.3 million euros).

But the far more significant reward is the knowledge she has reestablished her supremacy at a time when doubters were beginning to question the 34-year-old's hunger for more silverware after consecutive Slam final defeats this year.

In a testament to her remarkable longevity as the sport's preeminent force, Serena is once again Wimbledon's queen 14 years after her first success at the All England Club.

Equalling Margaret Court's all-time record of 24 Grand Slam titles will be Serena's next goal. The 71st singles title of Williams' astonishing career also moved her within two of Martina Navratilova's all-time record of nine Wimbledon triumphs.

Showing signs of cracking under the pressure of her bid for tennis immortality, Williams had cut a grumpy figure for much of the tournament, earning a fine for racquet smashing and threatening to sue Wimbledon officials if she was injured on a wet court.

But a serene focus came over Williams with the trophy in sight and she delivered a 48-minute masterclass against Elena Vesnina in the quickest semi-final in Wimbledon history.
