Scotland Women won their first match in the Six Nations since 2010 after a superb performance against Wales at Broadwood Stadium.
The Scots last claimed a victory in the tournament more than seven years ago when they defeated France 10-8 at Lasswade.
Captain Lisa Martin said: “I am so proud of this team, what a night and we can really build from here.”
Wales led 14-0 before Scotland came back into things.
Just before half-time, after two or three minutes of good play, centre Lisa Thomson ran a great line to crash over for a try.
Scrum-half Sarah Law converted and Scotland were right in this one at the break at 14-7.
With 20 minutes to go, winger Rhona Lloyd then had a good break and a few phases later Scotland bagged their second try through the same player.
With six minutes remaining Law then held her nerve to kick the winning penalty on a historic night.
