The Daimyo were the most powerful feudal rulers from the 12th century to the 19th century in the History of Japan. Similar to the "feudal" system in Europe, they held dynastic control over semi-autonomous territories, and lesser territorial lords were pledged to support greater ones. A warrior-caste of samurai soldiers likewise gave their personal loyalty to the support of lords from these families.
At the beginning of Edo period, their clans and territories were reorganized as han.
The term Daimyo (大名) is also sometimes used to refer to the leading figures of such clans, also called "warlords". It was usually, thought not exclusively, from these warlords that a shogun or regent was chosen.
Ashikaga Yoshiaki (1537 - 1597) was the 15th, and last Ashikaga shogun in Japan who reigned from 1568 to 1573.
The Ashikaga Shogunate, also known as the puppet Shogunate, was destroyed in 1573 when Oda Nobunaga drove Yoshiaki out of Kyoto.
