History of Samurai
702 AD Taihō Code - ‘samurai’ lower half of aristocracy, bureaucratic
civil servants. ‘samurai’ would not have military connotations for almost
2 centuries
between 9th and 12th century, rise of Shogunate and warrior samurai
class
1274 AD and 1281 AD - Mongol’s invade Japan, THIS CHANGES
EVERYTHING...
1584-1645 AD - Miyamoto Musashi, The Book of Five Rings
1876 AD - The samurai lose their profession and the right to wear
swords. The samurai position as a special class ended after ~1000 years.
brief and probably wrong

‘According to our manner of fighting
we must first call out by name someone
from the enemy ranks, and then
attack in single combat...’
‘But the Mongols took no
notice at all of such
conventions...’
--Hachiman Gudokun

The Samurai had no practical experience
against hardened armor, showering
arrows or mass maneuvering troops
but they had a strong Incentive to learn
really fast

‘samurai’ no
longer a
birthright

It is said the warrior's is the twofold
Way of pen and sword, and he should
have a taste for both Ways
--Miyamoto Musashi

the way
Do not think dishonestly.
The Way is in training.
Become acquainted with every art.
Know the Ways of professions.
Distinguish between gain and loss in worldly matters.
Develop intuitive judgement and understanding for
everything.
Perceive those things which cannot be seen.
Pay attention even to trifles.
Do nothing which is of no use.

Think lightly of yourself and

wonderful state which makes devops inevitable.
