More than 900 women are campaigning for public office in Saudi Arabia -- a first in the kingdom's history.

The December 12 municipal election will be the first opportunity for Saudi women to exercise their vote since a 2011 order by the now deceased King Abdullah that granted women some opportunities for political participation in the ultra-conservative kingdom.

According to the State Department, Abdullah issued a royal decree in 2013 mandating the Consultative Council, a royally appointed body that advises the King, be at least 20% women.

Critics have described the change as anywhere from modest to inconsequential. Women will only participate in elections at the municipal level.

At least two women's rights activists announced on Twitter that they had been disqualified as candidates.

Loujain Hathloul and Nassima al-Saada said their names had been left off the final candidates list, and that they plan to appeal.

Just three months ago, Saudi women were allowed to register to vote for the first time.
