The 10th October is the anniversary of the Battle of Tours.
Charles Martel, leader of the French forces, won a great victory near Tours which stopped the advance of Abdul Rahman Al Ghafiqi and his armies from Muslim Spain. The Umayyad made another attempt to invade France in 735, but it was to be their last. Thanks to Martel Islam spread no further than Spain, and the rest of Western Europe remained Christian.
The Umayyad were themselves rather astonishing, and there is much to admire about Al-Andalus, the state they created in Spain between 711 and 1492 - it was one of the most tolerant countries in the world, which produced remarkable scholarship and architecture. In fact, it was one of the most interesting periods of Spanish history. Muslims today would do well to emulate it.
