The Crusades was a campaign to regain the Holy Land from the Muslim
invaders after they took it over. Some
came to fight for that goal while others joined to see new lands while some
were after the riches that be taken from that area. Many were promised forgiveness of their sins
if they joined the Crusades. Still, some
of the effects of the Crusade were that the Mediterranean was open to trade as
soldiers and markets were established.

Very interesting question as there are actually three Indian dynasties during the classical period, which includes:
Maurya Dynasty(300-184BCE)
Kushan Dynasty(40-176AD)
Gupta Dynasty(320-550AD)
Gupta is the most influential one but at the same time the youngest. It might not be in the classical period depending on the source of interpretation.
I suggest you check your readings or ask your teacher to determine the span of the classical period.
Hope this helps!
