Makino Tadamasa

was a Japanese daimyō of the Edo period. 

The Makino were identified as one of the fudai or insider daimyō clans which were hereditary vassals or allies of the Tokugawa clan, in contrast with the tozama or outsider clans. 

Makino clan genealogy
The fudai Makino clan originated in 16th century Mikawa Province.  Their elevation in status by Toyotomi Hideyoshi dates from 1588.   They claim descent from Takechiuchi no Sukune, who was a legendary Statesman   and lover of the legendary Empress Jingū. 

Tadamasa was part of the senior branch of the Makino which was established at Tako Domain in Kōzuke Province in 1590;  and in 1616, their holdings were moved to Nagamine Domain in Echigo Province.   From 1618 through 1868, this branch of the Makino remained at Nagaoka Domain (74,000 koku) in Echigo Province. 

Tadamasa was the 10th-generation head of this senior line of the Makino. 

The head of this clan line was ennobled as a "Viscount" in the Meiji period. 

Tokugawa official
Tadamasa served as the Tokugawa shogunate's forty-eighth Kyoto shoshidai in the period spanning February 15, 1840, through December 23, 1843. 

Tadamasa held a variety of positions in the Tokugawa shogunate, including rōjū.   A staunch supporter of Abe Masahiro, when Tadamasa became a rōjū, he was placed in charge of organizing coastal defenses.  He resigned shortly after Hotta Masayoshi replaced the recently deceased Abe; Tadamasa himself died the following year.
