Moors never played a part in Switzerland's history. "Moors" typically is the name of the Islamic population of Spain. They invaded Spain in the 8th century and conquered a great part of south-eastern Spain.
After the defeat and death of their most succesful leader Al-Mansoor around 1000 A.D their role and power began to diminish. By around 1400 A.D the Moors had been reduced to a minority group more or less tolerated by the Spanish rulers. King Ferdinand and Queen Isabella of Spain finally forced them in the late 15th century to either convert to Catholicism or be deported from Spain.

Unknown. History doesn't record that far back.
I haven't seen a history text book in many years, so my information goes only as far as I can remember.
History goes back only as far as a written record can be found for that area. For some parts of the world history goes back several thousands of years. That includes Egypt, China and perhaps Greece. For the Americas, history goes back to 1492 or later for most parts of America.
