Saudi women are allowed to vote for the first time in the kingdom’s municipal elections.
Women are also standing as candidates, another first, despite the conservative kingdom being the only nation where women are not allowed to drive.
A total of 978 women have registered as candidates, alongside 5,938 men.
Female candidates have had to speak behind a partition during campaign appearances or be represented by a man.
Elections themselves are a rare thing in the Saudi kingdom – November 12 will be only the third time in history that Saudis have gone to the polls.
There were no elections in the 40 years between 1965 and 2005.
The decision to allow women to take part was taken by the late King Abdullah and is seen as a key part of his legacy.
In announcing the reforms, King Abdullah said women in Saudi Arabia “have demonstrated positions that expressed correct opinions and advice”.
Before he died in January, King Abdullah appointed 30 women to Saudi Arabia’s top advisory Shura Council.
There are 2,100 council seats available in today’s vote. An additional 1,050 seats are appointed with approval from the king.
The results of the elections are expected to be announced later on Saturday, December 12.
