Switzerland is one of the last nations in Western Europe to ban same-sex marriage. The Swiss parliament had already legalized gay marriage, but a group of conservative “Christian” political parties pushed for the decision to be revised in a referendum and put to vote.

On Sunday Swiss voters took to the pols and appear to have decided by a clear margin to allow same-sex couples to marry, according to a projection after a national referendum on Sunday.

The projection, by the gfs.bern polling agency for Switzerland’s public broadcasters, showed the measure passing by by a whopping 64% to 36%.

Switzerland, which has a population of 8.5 million, is traditionally conservative and only extended the right to vote to all women in 1990.

The passage means that t same-sex partners on an equal legal footing with heterosexual couples, by allowing them to adopt children together and facilitating citizenship for same-sex spouses. It would also permit lesbian couples to use regulated sperm donation.

Congratulations Switzerland!
