On 20 November 1915, a 2-0 win over Kilmarnock started an unbeaten run for Celtic that lasted a British record 62 matches.
Celtic, who had won the two previous league titles in 1914 and 1915, had gotten the new season of to a great start, jumping straight to the top of the table on the first day with a 3-1 victory over Motherwell. By mid-November, they were even on points at the top with Hearts and Rangers, but had lost three of the last four matches, with the most recent stumble coming against Hearts on 13 November.
One week later, they hosted Kilmarnock and won 2-0, thanks to goals from left back Joseph Dodds and center forward James McColl. They then proceeded to go unbeaten for the rest of the season, winning 23 and drawing three, to claim their third consecutive league title. They almost made it through the next season unbeaten as well, but finally fell to Kilmarnock at home, 0-2, on the penultimate day (though they still finished on top of the table for their fourth consecutive league title).
The 62-match unbeaten run (with 49 wins and only 13 draws) remains a British record.
