Under cool, gray skies billions watched from outside Westminster Abbey and on television worldwide as 1900 invited guests inside witnessed as Prince William and his longtime girlfriend Kate Middleton were married in one of the largest events in London in decades. A little over an hour after they arrived at the Abbey to be married, the couple emerged on a red carpet and onto the streets to a peal of bells and into a horse-drawn carriage, heading toward Buckingham Palace. The prince had married what the British call a commoner; now the Duke and Duchess of Cambridge (titles granted by Queen Elizabeth II). The couple stepped out onto a balcony a short time later to greet the enormous crowd along the Mall - a tradition at royal weddings. They kissed for the first time in public as a married couple as a cheer went up from the crowd. -- Paula Nelson ( 36 photos total
