or

of
the
major
Japanese
clans
in

at
the
start
of
the
Tokugawa
Shogunate.

More
about
that
period
below:

The
period
immediately
preceding
the
establishment
of
the
Tokugawa
Shogunate
in
1603
is
known
as
the


Azuchi-Momoyama
period
(1568–1600),
following
the
turmoil
of
the


Sengoku
(“Warring
States”)
period
(1467–1568).

This
era
was
characterized
by
intense
warfare,
shifting
alliances
among
powerful
daimyo
(feudal
lords),
and
the
gradual
consolidation
of
central
authority
culminating
in
Tokugawa
Ieyasu’s
establishment
of
a
lasting
shogunate.

Here’s
a
detailed
breakdown
of
this
turbulent
period,
with
special
attention
to
influential
clans
and
their
roles:

Background:
The
Sengoku
Period
(1467–1568)

This
period
was
marked
by
political
fragmentation
and
incessant
warfare
among
rival
daimyo.
Central
government
had
weakened
significantly,
and
local
warlords
competed
fiercely
for
power,
territory,
and
resources.

Key
Characteristics:

• 
  Decentralization
  of
  power—Japan
  divided
  into
  hundreds
  of
  domains
  ruled
  by
  independent
  daimyo.
• 
  Rise
  of
  castle
  towns—Daimyo
  constructed
  fortified
  castles
  as
  centers
  of
  political
  and
  economic
  control.
• 
  Emergence
  of
  professional
  samurai
  armies—Increased
  military
  specialization
  and
  extensive
  use
  of
  firearms
  (introduced
  by
  the
  Portuguese
  around
  1543).

Transition
to
the
Azuchi-Momoyama
Period
(1568–1600)

The
Azuchi-Momoyama
period
marked
the
gradual
reunification
of
Japan
under
a
few
dominant
daimyo.
It
derived
its
name
from
two
castles:

• 
  Azuchi
  Castle,
  built
  by
  
  Oda
  Nobunaga
• 
  Momoyama
  Castle
  (Fushimi
  Castle),
  built
  by
  
  Toyotomi
  Hideyoshi

This
era
saw
three
great
unifiers:

1. 
   Oda
   Nobunaga
   (1534–1582)
2. 
   Toyotomi
   Hideyoshi
   (1536–1598)
3. 
   Tokugawa
   Ieyasu
   (1543–1616)
