Yes there are Muslims all over the world, but there are a good number of Muslims in Western Europe, but it is not a major religion.
There are numerous areas of Europe that have been under control of Muslims. The Iberian Peninsula, Sicily, and the Balkan Peninsula are all sights of previous Muslim conquest. The Iberian Peninsula was conquered by the Umayyad Caliphate in the 8th century, Sicily was conquered by Muslims in the 9th century, and the Balkans came under Muslim control by the expansion of the Ottoman Empire in the 14th and 15th centuries. Today, the Muslim majority countries of Europe include Turkey, Azerbaijan, Kosovo, and Albania.
No single individual or nation has conquered all of Europe. However, a few have come close. The Romans conquered everything but Scandinavia, Napoleon conquered all but Eastern Europe and Great Britain, and Hitler conquered all except Spain, Protugal, Sweden, Switzerland, and Great Britain.
Napoleon Bonaparte of France conquered much of Europe in the 1800's, but he did not conquer all of it.
