Assuming you're pro-Columbus day, these are points that can be made:
Being historically accurate, Columbus day should be celebrated because he attempted and was successful at colonizing and helping America grow.
A common argument trying to counter being pro-Columbus day is the mention of killing Native Americans, so you can mention that diseases had already existed and were the primary cause of death in the New Land rather than Natives being killed (keep in mind though that disease and murder were both factors).
Another Pro argument that could be made is the fact that yes, vikings DID find America first, however Columbus helped Americas economy, etc.
Assuming you're anti-Columbus day, these are more points:
What Christopher Columbus did to Native Americans is unjust, essentially he took land from the Natives and they were forced to convert and change their lifestyle in order to work with Columbus or were killed; brutality is unacceptable.
The day itself should be focused on the Native American victims of Columbus.
The vikings technically found the New Land.
I hope this helped a little! :)
Answer:
Like in medieval Europe, Japan developed a feudal system dominated by a warrior aristocracy outside of the weak central government. The emperor was the head of feudal society in name only. The shogun, the military commander, held the real power. The shogun gave lands to vassal lords, daimyo, who supported him.
It was different because it remained independent during the colonial era when the rest of South East Asia was colonized. It modernized itself and worked with both British and French colonies but remained independent and chose who they wanted to work with. The territory of Siam is what is nowadays known as Thailand, so you can see that Thailand managed to develop itself and its culture independently of the colonizers who ran rampant among the South East Asian region and which caused many wars in recent times.
