蘆名氏
Before the late 12th century, Aizuwakamatsu was mainly a market town and a base for regional warlords. Starting in 1192, Aizuwakamatsu became part of the regions that were controlled by the Kamakura shogunate. Soon after taking power, Yoritomo granted a samurai named Suwara Yoshitsura (from the Miura clan) all of Aizu. A descendant of Suwara, Ashina Morinori, began construction of the first castle in the city in 1384. During the Sengoku period the final lord of Aizu, Ashina Moritaka, died in 1583 and soon the Ashina clan lost power. After the Satake clan took control of the castle, they placed a twelve-year-old member of their clan who was renamed Ashina Morishige and proclaimed lord of Aizu. The Ashina clan regained control of Aizu for a brief time in 1589 with the help of Date Masamune. However, Masamune took over the domain for himself soon after. He surrendered in 1590 to Toyotomi Hideyoshi. Toyotomi gave Aizu to one of his allies, Gamo Ujisato who then began construction in 1592 of a new castle at the site. It was during this time that the town was renamed "Wakamatsu" (young pine).
