when was last time ireland won grand slam
Grand Slam (rugby union) In rugby union, a Grand Slam (Irish: Caithréim Mhór. Welsh: Y Gamp Lawn. French: Grand Chelem) occurs when one team in the Six Nations Championship (or its Five Nations predecessor) manages to beat all the others during one year's competition. This has been achieved 39 times in total, for the first time by Wales in 1908, and most recently by Ireland in 2018. The team to have won the most Grand Slams is England with 13.
Grand Slam (golf) Only Bobby Jones has ever completed a Grand Slam. No man has ever achieved a modern era Grand Slam. Tiger Woods won all four events major events consecutively within a 365-day period, but his victories were spread over two calendar years.
