In the 2014–15 season they won the Pro12 title and became the first Scottish team to win a major trophy in rugby union's professional era.

[16] Only two professional sides remaining meant that the 1998–99 Scottish Inter-District Championship was fought out in a three match 'Tri-Series' battle between Glasgow and Edinburgh.

The SRU realised that Glasgow and Edinburgh needed more competition domestically than each other and so began a successful dialogue with the Welsh Rugby Union that resulted in both Scottish sides being entered in the WRU Challenge Cup in early 1999.

Although both Glasgow and Edinburgh finished no higher than mid-table for those three seasons, it did provide the Scottish sides with much needed competition.

The Irish Rugby Football Union began talks with the SRU and WRU about further extending the co-operation in a new Celtic League.

The Celtic League began in truncated fashion in the autumn of 2001 with the addition of the four Irish provincial teams in two pools; Glasgow reached the semi-finals of the inaugural competition, but struggled thereafter.

Glasgow, Edinburgh and the Borders fought in out in what was the final professional Inter-District championship; the Bank of Scotland Pro Cup.

In his second to last season in 2009-10 the team managed 3rd and secured a semi-final against Ospreys - the club's first Celtic League semi final since 2001-02.

With only two professional sides once again, the SRU took the opportunity to dust down and rename the 1995 Scottish Inter-District Championship trophy and use the two Celtic League fixtures between Glasgow Warriors and Edinburgh Rugby as a mini-cup tournament.

The Irish were again confident but Glasgow simply blitzed Munster in the final winning 31 - 13 for the Warriors first league title since the 1999-2000 Scottish Inter-District Championship 'Tri-Series'.

Glasgow also successfully defended their Melrose Sevens title, beating the German international 7s side in the final.

They beat Glasgow in Galway in the semi-final, with Finn Russell injured with a serious cheekbone fracture at the start of the match.

[24] For the Pro14's inaugural season, Glasgow Warriors were placed in a conference with the Ospreys, Blues, Munster, Connacht, Zebre and Cheetahs.

Other than a blip against the Southern Kings and a notable dip in the Festive period against Edinburgh and Benetton Treviso, by and large Glasgow Warriors seemed to ease through their fixtures.

[30] They narrowly lost to Leinster in the final at Celtic Park following an error by Stuart Hogg in the Warriors try-line.

By the end of February 2020, Glasgow Warriors had solidified the play-off 3rd spot and were hopeful of a decent run to overtake Ulster into the 2nd place in their conference.

The season restarted at the end of August; but it was instead curtailed, now with only two matches to play, meaning it was virtually impossible to catch Ulster in the second spot.

The Southern Kings went bankrupt and the Cheetahs were unable to compete due to the pandemic, so the Pro14 ran with 12 European sides, still in two conferences.

Beaten by both European winners may have been understandable but the Glasgow side's league form was much worse and a run of away fixtures hardly helped.

The SRU was quick to act in the face of these poor results and Danny Wilson was stood down as Head Coach.

A red card to Tom Jordan made it difficult for the Warriors and they lost the match 14–5 to the Irish side.

Nevertheless, it was a very successful first season under Smith, with the side back challenging on all fronts after the slump of the Danny Wilson era.

Indeed, only the Stormers, the Sharks, Edinburgh and Cardiff managed to prevent Glasgow taking the bonus point win there.

In blustery conditions the Warriors comfortably won the match, helped by the Stomers poor kicking in the wind.

Munster displaying advertising promoting the final between them and the Bulls before the match gave Glasgow extra impetus and they outplayed the Irish side.

Rugby at Scotstoun, however, goes back even further, right to the beginning of the 1900s when the likes of Glasgow HSFP and Kelvinside Accies along with others played there on their journeys to Old Anniesland and Balgray respectively.

In 2012, Glasgow Warriors moved from Firhill back to Scotstoun Stadium, which had previously been the club's training base.

[45] In addition to those grounds above:- Rugby Park in Kilmarnock;[46] Old Anniesland in Glasgow;[47] Braidholm in Giffnock;[48] Whitecraigs in Newton Mearns;[49] London Road in Stranraer;[50] Burnbrae in Milngavie,[51] North Inch in Perth[52] and Murrayfield Stadium in Edinburgh[53] have all hosted home matches for the Glasgow side.

[70][71] The 2016-17 European Champions Cup Quarter Final away to Saracens saw 6000 of the Warrior Nation make their way to Allianz Park and provided the London side with their highest ever home attendance.
