Niwa clan
In 1600, the Niwa clan sided with Ishida Mitsunari's Western Army against the Tokugawa at the Battle of Sekigahara and was thus dispossessed. The victorious Tokugawa Ieyasu chose to be magnanimous, and with the establishment of the Tokugawa shogunate, awarded Niwa Nagashige with a 10,000 "koku" domain in Hitachi Province. Nagashige's forces fought well at the 1614 Siege of Osaka, and in 1619 his revenues were increased to 20,000 "koku", and in 1622 he was transferred to the 50,000 "koku" Tanakura Domain in Mutsu Province. In 1627, he was transferred once again to Shirakawa Domain, at 100,700 "koku".
