The Ii ( Japanese 井 伊 氏 , Ii-shi ) were a family of the Japanese sword nobility ( Buke ), which was derived from Fujiwara no Yoshikado. With an income of 340,000 Koku at times , the Ii residing in Hikone ( Shiga Prefecture ) belonged to the great Fudai daimyo of the Edo period .
Naomasa (1561-1602) served under Tokugawa Ieyasu , from whom he received the Minowa Castle ( Kōzuke ) with an income of 12,000 koku . After Naomasa had excelled in the battle of Sekigahara by defeating Shimazu Yoshihiro, Ieyasu enfeoffed him with Sawayama ( 佐 和 山 ) ( Ōmi ) and an income of 180,000 koku. Naomasa moved into the castle, but died soon after from injuries sustained in battle.
- Naokatsu ( 直 勝 , 1590–1662), eldest son, see below.
- Naotaka ( 直 孝 , 1590–1659) was Naomasa's second son. In 1605 he joined the Shogun Tokugawa Hidetada , who in 1610 gave him an income of 10,000 koku in the province of Kōzuke and the honorary title Kamon no kami to him and his descendants. When his older brother Naokatsu refused to take part in the siege of Osaka in 1615, he lost his fiefdom to Naotaka by order of Hidetada. Naotaka completed the construction of Hikone Castle, which Naokatsu had begun in 1603, and moved into it as a residence in 1623. His income was first increased to 290,000 koku, in 1633 to 340,000.

- Naonaka ( 直 中 )
- Naosuke (直 弼 , 1815-1860) was Naonaka's 14th son. With the exception of his eldest brother, who was destined to succeed him, all others were adopted by daimyo families. He himself stayed in Hikone and then became Prince of Hikone in 1845 when his older brother died childless. In 1858 he wasappointed Grand Chancellor ( tairō )by the Shogun Tokugawa Iesada . Naosuke signed the Unequal Treaties with the US, France and England, which led to unrest across the country. Naosuke responded with arrests and death sentences, which has gone down in historyas the " Ansei Purge ". The opening of more treaty ports , a treaty with Portugal, and other circumstances the following year fueled the unrest. On March 24, 1860, Naosuke was attacked and killedon the way to the Shoguns Palace in front of the Sakurada Gate .
- Naonori ( 直 憲 , 1848–1904), son of Naosuke, followed as head of the house with an income reduced to 240,000 koku until the Meiji restoration . After that, the head of the house carried the title Graf .
- Naokatsu had succeeded Naomasa in 1602, lived in Sawayama Castle, but was obliged to build Hikone Castle . When he stayed at his castle during the war for Osaka and did not take part in the fighting, Hidetada transferred the great fiefdom to his brother Naotaka, but left him Annaka ( Kōzuke ) with 30,000 koku. The family was transferred to Nishio ( Mikawa ) in 1645 , to Kakegawa in 1658 and to Yoita ( Echigo ) in 1705 with 20,000 koku. After the Meiji Restoration, this branch bore the title Vice Count.
