That a man should mate with a woman and be together as a couple is mentioned in the Hebrew Scriptures, penned by Moses around 3000 years ago, and rumor has it, this started with Adam and Eve. No one throughout history has ever rebuked that claiming that it started with anyone else, so figure it goes back a long, long time.
In ancient days, and down to today, the couple's intent to marry would involve some form of public demonstration that served to acknowledge the union in front of witnesses or village elders, what we would call a "ceremony". Then churches got involved basically because they're power wh0res, and eventually the government took over. Now, marriage is a civil contract that, insofar as religion is involved, clergy need a gov't license to officiate when they perform the ceremony. which is why you'll hear them say, "and now with the powers vested in me by the State of... I now pronounce you husband and wife".
This ceremony has evolved, in some cultures, where it's all about the bride. This is to impress upon the male that he ought to deem himself lucky to be there and be had by her. And in most cases, he will be had by her.
It's all summed up in the movie "Father Of The Bride", where the groom-to-be asks the wedding planner, "And what should I do?", to which the wedding planner replies, "See the guy on top of the cake? Dress like him and show up."
I was at a Hindi wedding, and wow, the groom dresses like a King and rides up on a gilded horse to the bride while everyone dances in joy before him, and he is then honored by his wife-to-be when she greets him and adorns him with garlands.
If western wedding ceremonies were really taking the guy into account, they'd involve some sort of fishing trip and a couple of strippers, that's what I say. But I digress.
Since its humble beginning with whoever was the first couple, it has spread like wildfire throughout the world and all civilizations down through the ages, to where nowadays most people either are married, have been married, or know someone who is or has been married. They may even have a married person in their family. If you are approached by marriage, please be cautious.
