17 February 1894 - The First Old Firm Final

On 17 February 1894, Rangers won their first Scottish Cup, beating Old Firm rivals Celtic 3-1. They currently have 33, while Celtic have 34.

Rangers and Celtic had already played once that season in the league, with Rangers winning by the comfortable margin of 5-0 thanks in part to a hat-trick from midfielder John Barker. Barker struck again in the Cup Final, played at Glasgow's Cathkin Park (then known as the second Hampden Park).

The first goal, however, came from defender Hugh McCreadie, who played in Rangers' central defense alongside his brother, Andrew. Barker doubled the lead, then midfielder John McPherson added a third. Celtic, who had won the Cup two years earlier and were the reigning league title-holders, finally got a late consolation goal from half-back Willie Maley.

Although they lost the Cup, Celtic exacted their revenge one week later, beating Rangers 3-2 in the league en route to winning that season's title.

14 April 1917 - They've Had A Bit Of Success Since Then, As Well

On 14 April 1917, Celtic beat Hibernian in Edinburgh by the score of 0-1. The win put a bookend on Celtic's record streak of 62 unbeaten league matches, a streak that started the previous season with a 2-0 home win over Kilmarnock on 20 November 1915.

The streak was a small part of Celtic's overall dominance of the Scottish league of the period, which saw them them win four consecutive league titles from 1915-1918 under manager Willie Maley. Maley was one of the first players signed by Celtic in their inaugural season in 1888 and became their first manager in 1897. He retired in 1940, making him Celtic's longest-serving manager. In those 43 years, Maley helmed Celtic to 30 major trophies, including 16 league titles.

Coincidentally, the team at the front end of Celtic's unbeaten streak - Kilmarnock - ended it on 21 April 1917, beating the Hoops in Glasgow by the score of 0-2.
