I am sure your children were not taught this in school. I wasn't. More scrubbing of history in compliance with the sharia.
Christopher Columbus on Santa Maria in 1492
Columbus and Islam Citizen warrior, October 14, 2013 (thanks to Jim)
In 1492, Columbus sailed the ocean blue. We all know the New World was discovered because Christopher Columbus was looking for a trade route to the East.
But was he looking for a trade route? Because during its second great jihad, Islam had invaded Central Asia and defeated Constantinople in 1453, cutting off the overland route for Europeans. Islamic armies continued their jihad northward, and conquered much of what is now Eastern Europe, until they were finally stopped at the gates of Vienna in 1529 (on September 11th).

According to Greg Nyquist in "Ayn Rand Contra Human Nature," one of the biggest factors leading to the poverty and strife of the dark ages was the Muslim Conquests of the seventh, eighth and ninth centuries AD, cutting off trade to western Europe. He quotes as his source of information, a book called Medieval_Cities.
Here is part of an Amazon.com customer review Nyquist wrote, describing what he read in the book. Talking about "Medieval Cities" he wrote,
This is a groundbreaking work in the study of the so-called "Dark Ages." Pirenne, one of the great scholars and historians of the 20th century, discovered that the economic destitution of Western Europe during the 8th, 9th, and 10th centuries was a consequence, not of the barbarian invasions, as is commonly supposed, but of the Islamic presence in the Mediterranean. The astonishing advance of Islam into Northern Africa, Spain, and Syria during the 7th and 8th centuries meant that Western Europe lost control of the Mediterranean. It became, as Pirenne puts it, a "Moslem lake," and because of this, Western Europe found itself in what amounted to a state of virtual blockade. All the trading routes to the East were cut off and Gaul and other Western European countries were thrown back on their own resources. Bereft of the economic lifeblood of trade, cities shrunk into insignifance. Marseilles, once a thriving seaport, became a ghost town. The Middle Class ceased to exist. Complete autarky reigned in the West. The economic devestation was so bad that Charlemagne's government could not collect any taxes. All of Charlemagne's revenues came from his own estates.
