Matsudaira Yoritane

The was a Japanese samurai clan that descended from the Minamoto clan. It originated in and took its name from Matsudaira village, in Mikawa Province (modern-day Aichi Prefecture). During the Sengoku period, the chieftain of the main line of the Matsudaira clan, Matsudaira Motoyasu became a powerful regional daimyo under Oda Nobunaga and Toyotomi Hideyoshi and changed his name to Tokugawa Ieyasu. He subsequently seized power as the first shōgun of the Tokugawa shogunate which ruled Japan during the Edo period until the Meiji restoration of 1868. Under the Tokugawa shogunate, many cadet branches of the clan retained the Matsudaira surname, and numerous new branches were formed in the decades after Ieyasu. Some of those branches were also of '' daimyō'' status.

After the Meiji Restoration and the abolition of the ''han'' system, the Tokugawa and Matsudaira clans became part of the new nobility.

Origins

The Matsudaira clan originated in Mikawa Province. Its origins are uncertain, but in the Sengoku era, the clan claimed descent from the medieval Seiwa Genji branch of the Minamoto clan. According to this claim, the founder of the Matsudaira line was Matsudaira Chikauji, who lived in the 14th century and established himself in Mikawa Province, at Matsudaira village.

National historic sites

The location of Matsudaira village is within the borders of the modern city of Toyota, Aichi. A number of locations associated with the early history of the clan were collectively designated a National Historic Site of Japan in the year 2000. These include:

# The ruins of a Sengoku period fortified residence on the eastern bank of the Tomoe River (Asuke River) which was the birthplace of Tokugawa Ieyasu. The site is now part of a Shinto Shrine, the Matsudaira Tosho-gu, which was built in 1615, after Tokugawa Ieyasu's death and deification.
# Matsudaira Castle, from which the Matsudaira clan ruled over a portion of Mikawa Province during the Sengoku period.

Sengoku period

Minor power between major neighbors

In its territory in Mikawa Province, the Matsudaira clan was surrounded by much more powerful neighbors. To the west was the territory of the Oda clan of Owari Province; to the east, the Imagawa clan of Suruga. Each generation of Matsudaira family head had to carefully negotiate his relationship with these neighbors.

Branches of the Matsudaira clan

Before the Edo period, there were 19 major branches of the Matsudaira clan: , , , , , , , , , , , , , , , , , , and . Each of these branches (with the exception of the Kaga-Matsudaira, which relocated to Kaga Province) took its name from the area in Mikawa where it resided. Also, many of the branches often fought with each other.

Matsudaira of Okazaki

It was the main Matsudaira line residing in Okazaki Castle which rose the highest during the Sengoku period. During the headship of Matsudaira Hirotada, it was threatened by the Oda and Imagawa clans, and for a time was forcibly brought into Imagawa service. After the death of Imagawa Yoshimoto and the fall from power of the Imagawa clan, Hirotada's son Matsudaira Motoyasu was successful in forming an alliance with Oda Nobunaga, the hegemon of Owari Province. Motoyasu is better known as Tokugawa Ieyasu, who became the first Tokugawa shōgun in 1603.

Matsudaira branches and the use of the surname

Pre-Edo branches

Several of the pre-Edo branch families survived into the Edo period; some of them became '' daimyōs''. The Takiwaki-Matsudaira family became ''daimyōs'' of the Ojima Domain, and from 1868 to 1871, ruled the Sakurai Domain. The Nagasawa-Matsudaira, also known as the Ōkōchi-Matsudaira, had several branches, one of them ruled the Yoshida Domain of Mikawa Province. A prominent Nagasawa-Matsudaira is the early Edo-period politician Matsudaira Nobutsuna. The Fukōzu-Matsudaira ruled the Shimabara Domain. The Sakurai-Matsudaira ruled the Amagasaki Domain. The Ogyū-Matsudaira had many branches, one of which ruled the Okutono Domain. Nagai Naoyuki was a prominent Bakumatsu-era descendant of the Ogyū-Matsudaira of Okutono. Other pre-Edo branches of the family became hatamoto.

Tokugawa branches and the Matsudaira surname

The Tokugawa surname was not granted to all of the sons of the shōgun or the heads of the six main Tokugawa branches. Only the inheritor received the Tokugawa name, while all of his siblings would receive the Matsudaira surname. For example, the last shōgun Tokugawa Yoshinobu was not the firstborn heir of his father ( Tokugawa Nariaki of Mito). Consequently, Yoshinobu was known as Matsudaira Shichirōma during his minority. Some of these sons, particularly of the 3 main Tokugawa branches (the '' Gosanke''), formed their own families, and received their own fiefs. These included Takamatsu, Shishido, Fuchū, and Moriyama (branches of the Mito Tokugawa); Saijō (a branch of the Kii Tokugawa); and Takasu (a branch of the Owari Tokugawa). Notable Matsudaira of these branches include Matsudaira Yoritoshi of Takamatsu, and Matsudaira Yoritaka of Fuchū. Yoritsune Matsudaira and his son Yoriaki Matsudaira, who were 20th-century composers, were descendants of the Matsudaira of Fuchū.

Yūki-Matsudaira clan (Echizen)

The Yūki-Matsudaira clan was founded by Tokugawa Ieyasu's son Yūki Hideyasu. Several branches of the Yūki-Matsudaira came into existence during the Edo period. Though the Yūki-Matsudaira retained control of Kitanoshō (later renamed Fukui), the main Yūki line was not there, but in Tsuyama instead. Branches of the family ruled the Fukui, Hirose, Mori, Matsue, Tsuyama, Akashi, Itoigawa, and Maebashi domains. Famous Yūki-Matsudaira include Matsudaira Naritami and Matsudaira Yoshinaga, two ''daimyōs'' of the late Edo period. Matsudaira Yoshinaga in particular was very important to Japanese politics of the early Meiji period, and his leadership put the Fukui Domain on the side of the victors in the Boshin War (1868–69).

Hisamatsu-Matsudaira clan

The Hisamatsu-Matsudaira clan was founded by Tokugawa Ieyasu's half-brother Hisamatsu Sadakatsu. Due to his close relation to Ieyasu, Sadakatsu was allowed the use of the Matsudaira surname. Eventually, some of the branches of the Hisamatsu-Matsudaira were also allowed the use of the Tokugawa family crest, as well as being formally recognized as Tokugawa relatives (''shinpan
