....Sigh.... WELL i just got done typing a bunch and then lost it so im going to redo it real quick with the highlights. NOW. its important to remember that a culture will HAVE religion, but the marriage was not religious bound. Normally they were bound in community, contractual, and arranged. IE
Ugandans had a rather lengthy process of courtship..after a long ceremoniously drawn out courtship it was cemented:
WIKI--
also customary for a boy to take a fat male goat to be slaughtered at the girl’s father’s home. This goat was known as esidis

n this occasion; the girl’s father would stand on it and be smeared with simsim oil. This male goat was meant o cement the marriage and it acted, in addition as a common bond between the two families.
Pygmy wedding traditions
Pygmy engagements were not long and usually formalized by an exchange of visits between the families concerned. The groom to be would bring a gift of game or maybe a few arrows to his new in-laws, take his bride home to live in his band and with his new parents. His only obligation is to find among his relatives a girl willing to marry a brother or male cousin of his wife. If he feels he can feed more than one wife, he may have additional wives
Traditional Chinese marriage is a ceremonial ritual within Chinese societies that involve a marriage established by pre-arrangement between families. Within Chinese culture, romantic love was allowed, and monogamy was the norm for most ordinary citizens. A band of musicians with gongs and flute-like instruments accompanies the bride parade to groom's home. Similar music is also played at the wedding banquet. Depending on the region that the bride hails from, Chinese weddings will have different traditions such as Tea Ceremony or the use of a wedding emcee. Also in modern times, Chinese couples will often go to photo studios to take "glamour shots" posing in multiple gowns and various backgrounds.
AND OF COURSE>.....Scientologists.....they are just wierd
in addition...Here is the source of the christianity man/woman marriage:
Sermons from St. Augustine's letters (written around 350 A.D.) were popular and influential. In 534 AD Roman Emperor Justinian criminalized all but monogamous man/woman sex within the confines of marriage. The Justinian Code was the basis of European law for 1,000 years.
Several exceptions have existed for various Biblical figures, incestuous relationships such as Abraham and Sarah [1], Nachor and Melcha [2], Lot and his Daughters [3], Amram and Jochabed [4], and more [5][6][7]
I think i got those right. There are a few more i can't recall and don't have the time to look up right now. Oh...North Korea if i recall correctly. They worship Kim ...crazy communists...
Imperial cultures could pretty much be included in that list for the most part i believe.....i really should have kept my notes..
NOW...one more thing. I do believe marriage should not be temporarily licensed. However.....SINCE people want to base marriage off of religion then we should base ALL of it off of religion. No remarrying if divorced, women are property and should listen to thier husband, all the other fun stuff.
