The early Romans kissed the mouth or eyes as a form of noble greeting. One Roman emperor allowed his important nobles to kiss his lips, but the less important ones had to kiss his hands, and the least important ones were only allowed to kiss his feet!

The first society where the kiss became accepted in marriage was in France. From France the kiss spread rapidly all over Europe. As marriage customs developed, the kiss became a part of the wedding ceremony. Today we regard it as an expression of love and tenderness. But there are still many places in the world where the kiss is part of formal ceremonies and is intended to show respect.
