The Ottoman Empire was religiously tolerant and motivated by conquest as well. (The irony of the 20th century is that if the empire could have staved off its breakup for just a little longer, they would have had Iraq's oil wealth to back them up and very well could have developed into a modern superpower.)
A point, re muslim expansion to the Balkans. But still, just the Spain/Persia/Iran expansion makes the Crusades look like a tea party with centenarians.
But where the Ottomans religiously tolerant in all periods?
It seems the Turks where really disliked by their subjects (both in Middle East and in the Balkan), where did that come from, then?
(Let us bunch the Crusades as one single example, at least for this argument.)
(The Huns/Mongols were religiously tolerant and motivated by conquest, right?)
