Most of this is just random thoughts that I've had and I haven't fact checked them lately, and I'd welcome people to try disprove them. I'm pretty sure on the Sikhism part though.
In Mosaic law, women were treated better then they were in Pre Islamic Arabia, but women did not have equal rights.
In Ancient Egypt, women had total equal rights, but lived in a more patriarchal society then say modern day Secular Egypt.
In Ancient Rome, women were 'free' and were citizens, but had no right to vote, take office etc.
In Early Christianity, some work was done to make society more egalitarian, if the women complied with the Christian church. Basically they could take up small pastoral roles.
Ironically, Islamic law actually increased Womens rights in Arabia in a lot of cases. They had rights in marriage, divorce, and property well before a lot of the West.
In Scandanavia, before Christianity came to play, Women had equal rights to men. After which they were under tutelage.
In Ireland, under Brehon law women were treat civilly but as second class citizens. They had no right to property, but weren't treated as bad as in GB which had mental laws on witchcraft and with slavery laws.
A trend that seems to follow is the fact that under no religion at all women were treated equally. Under primitive religions they were mostly treated awfully, until major religions came to play and lifted them to a certain standard, but have fell short of expected standards.
One religion I'll compliment on there treatment of women is Sikhism, under which women and men have totally equal rights.
From woman, man is born; within woman, man is conceived;
to woman he is engaged and married.
Woman becomes his friend; through woman, the future generations come.
When his woman dies, he seeks another woman; to woman he is bound.
So why call her bad? From her, kings are born.
From woman, woman is born; without woman, there would be no one at all.
