Don,
You implied on an earlier post that because of my views on Islam I was a racist. I would remind you that there are many in the Islamic religion that are not Arab's or people of color. Many people in the Balkans are Muslims because of incursions by the Muslims into Europe during the middle ages.
Islam spread into Europe as far west as France before being defeated by Charles Martel, the grandfather of Charlemagne, at Tours, France in 732 AD [Halley. page 717]. Part of Spain remained under control of Islam [the Moors] until 1492 AD when Ferdinand defeated the last Moorish army at the gates of Granada and drove them back to Africa [Schaff, Volume IV, page 173]. Islam is still present in some Balkan states [eg.,Bosnia and Kosovo, part of the former Yugoslavia, and Albania].
The second major assault against the Christian nations by Islam, this time by the Turkish Empire [Halley, page 719; see also Henry, Volume 6, page 1153 and Carroll, page 114]. Artillery [fire, smoke, and brimstone] was first used in the Turkish assault and capture of Constantinople in 1455 AD. Under the Turkish Empire, Islam penetrated as far west as Vienna [Austria] where they were defeated by a Polish army under John Sobieski in 1683 AD.
