Serena Williams clinched her third Wimbledon title and 11th Grand Slam crown with a 7-6 (7-3) 6-2 victory over her sister Venus, the defending champion, on Saturday.
The final was the fourth all-Williams title match-up at Wimbledon and eighth in all Grand Slams with the win giving Serena the edge in head-to-head meetings at 11-10.
The victory added to her 2002 and 2003 wins at the All England Club.
"It feels so amazing. I'm so blessed. I feel like I shouldn't really be holding the trophy, Venus should be holding it, she always wins," said Serena who currently holds three of the four Grand Slam titles.
Venus, 29, who had been bidding to become the first woman to win a hat-trick of titles since Steffi Graf in 1993, paid tribute to her sibling.
"She was just too good today. She had an answer for everything and played the best tennis," she said.
Serve dominated the first set with 27-year-old Serena fighting off the only two break points in the eighth game and it was the younger of the two sisters who seized control of the tiebreak.
Serena went to three set points by forcing Venus to scramble from side to side before putting away a powerful crosscourt forehand.
Venus saved the first set point but was powerless when a pinpoint lob from her sister left her stranded at the net.
It was the first set Venus had dropped at Wimbledon since the third round in 2007, a run of 34 consecutive winning sets.
Serena carved out her first set point when Venus double-faulted to hand her a 4-2 lead and revenge for last year's final defeat to her sister looked likely.
Second seed Serena held to love, backed-up by her 12th ace of the match, to lead 5-2.
She then wasted three match points in the eighth game but clinched the title when Venus netted with a forehand.
The Williams sisters went on to win the women's doubles title at Wimbledon, beating Australian duo Samantha Stosur and Rennae Stubbs in straight sets.
