On 28 April 1965, Glasgow's Third Lanark AC lost at home to Motherwell, 0-2, on the last day of the Scottish First Division season. It was Thirds' thirtieth loss of the season and their twenty-first in a row, which remains the longest losing streak in any season throughout Scottish League history.
Third Lanark started life as the footballing unit of Third Lanarkshire Rifle Volunteers, but separated from the military in 1903, taking the name Third Lanark AC. They enjoyed some early successes, winning one league title (1904) and two Scottish Cups (1889, 1905). The success didn't last, however, and they were relegated to the Second Division at the end of the 1924-25 season and spent the next several years moving back and forth between the top two flights.
By the 1964-65 season, they had been back in Division One for seven years and had finished as high as third in 1961. But they got progressively worse in the next few seasons, finishing one spot out of the relegation zone in 1964. They were not so lucky the next year.
Thirds were already sitting near the bottom of the table when their losing streak began on 28 November with a home loss to Celtic, 0-3. The worst defeats in the string were away to Rangers (5-0), St. Johnstone (5-0), Dunfermline Athletic (8-0), and Dundee (6-1). They hit the absolute bottom of the table on 9 January after a 3-1 away loss to Hearts and remained there for the rest of the season, finishing with only seven points out of 34 matches.
They spent two seasons in Division Two, after which the club was liquidated. They played their last match on 28 April 1967, a 5-1 away loss to Dumbarton FC.
In 1971, supporters re-formed the club as an amateur side. They currently play in the Greater Glasgow Amateur League, Division Three.
