Rangers played a total of 39 competitive matches during the 1898–99 season.
[1] They finished top of Scottish League Division One with a one hundred percent record of 18 wins from 18 matches.
The club ended the season without any other trophies: in the Scottish Cup, despite beating Hearts and St Mirren en route to the final, they lost to Celtic 2–0.
[2][3] Earlier in the season they had also lost in the final of the less important Glasgow Cup 1–0 to Queen's Park,[4][5] and at its end they lost in the minor Glasgow Merchants Charity Cup final, another 2–0 loss to Celtic,[6] also finishing as runners-up to the same opponents in the supplementary Glasgow Football League.
[7] Regardless of these setbacks, the perfect league campaign of 1898–99 remains a unique achievement in the annals of British football.
