Depends on what culture you're asking about.

In Biblical times there was no such thing as a Mesader Kiddushin (roughly, one who officiates at Jewish weddings).
I should note that in Judaism "officiating" is not the same as "making the union effective".
i.e. there is no such concept of "By the power invested in me, I shall now pronounce you husband and wife".
The rabbi HAS no such power and cannot make someone husband and wife through a pronouncement.

In the ancient Near East marriages were always arranged. In ancient Israel the marriage covenant (b'rith) was part of the civil law, and there were legal papers that were drawn up which defined the rights of the husband and wife. The wedding ceremony (Chuppah) was all about bringing the bride to the bridegroom's house. The ceremony itself would last 7 days, sometimes longer. There would be great rejoicing and celebration late in the evening on the streets, and also when they arrived for the feast at the bridegroom's house. Once they entered the doors were shut and the wedding ceremony began. The bridegroom would spread the tip of his upper garment over her, then they would proceed to the wedding chamber, then to the feast. There were many friends and relatives, some would travel long distances. The fall was an ideal time for a marriage because it was after the harvest.
