Twickenham was opened as the RFU's new home in 1910. This heralded a golden era for English rugby union. England's first international at Twickenham brought them success over Wales, and England won the International Championship (also known as the Five Nations) for the first time since the great schism of 1895. Their title coincided with the rise of Harlequin F.C., whose brand of attacking rugby led to a purple period in the years leading up to the Great War. England did not retain the title in 1911; winning and losing two games. England only lost one game (to Scotland) in the 1912 Five Nations, and thus shared that championship with Ireland. A Grand Slam of the Five Nations was achieved by England in 1913 (meaning they won every game). England successfully defended the title at the 1914 Five Nations, and achieved another Grand Slam.
