Jerry Brown announced Tuesday that he will allow same-sex couples to marry in the state beginning this summer.
He also said that he plans to extend marriage licenses to all same-gender couples.
The governor also announced that his state will become the 28th in the nation to allow same sex couples to adopt.
The move is an important victory for LGBT advocates, who have been pushing for more recognition for gay and lesbian couples.
The decision comes just a week after Gov.
Brown signed a bill allowing same-day same-meal marriage licenses in California.
The bill also allows same-level marriage licenses for same- sex couples in Arizona and New Mexico.
In New Mexico, marriage licenses will be issued in late June, with the licenses to become valid in early July.
The California governor said he had been considering extending same-time marriage licenses as early as this year.
