"The Power of the Dog' director Jane Campion is an Oscar winner.
Campion on Sunday won the award for best director, becoming the third woman to win the prize.
The first was Kathryn Bigelow, who won for "Hurt Locker" and "Nomadland" director Chloé Zhao won last year.
Last month, Campion made history when she became the first woman to ever be nominated twice in the category.
Her first nomination was for the 1993 film "The Piano." That same year, she won an Oscar for best screenplay for the same movie.
When Campion earned her first nomination, she was only the second woman ever nominated in the category. The first was Lina Wertmüller, nominated for 1976′s "Seven Beauties."
In recent years, women have been better represented in the category. Two women -- Emerald Fennell ("Promising Young Woman") and eventual winner Zhao -- were nominated in the category in the same year for the first time.
Campion was the favorite to take home the award tonight.
Her fellow nominees were Kenneth Branagh ("Belfast"), Ryusuke Hamaguchi ("Drive My Car"), Paul Thomas Anderson ("Licorice Pizza") and Steven Spielberg ("West Side Story").
Spielberg previously beat out Campion in this category in 1994 with his win for "Schindler's List."
