Andō Morinari served as lord of Kitagata Castle in Mino Province.
The Andō clan of Mino were originally under the Iga name.
Morinari began as a retainer of Toki Yoriaki, then joined Saitō Dōsan after Dōsan usurped Yoriaki and garnered control of Mino Province. Together with Inaba Yoshimichi and Ujiie Naomoto, Morinari was deemed one of the Western Mino Group of Three – senior retainers of the Mino-Saitō who later defected to serve Oda Nobunaga.
In 1556, Morinari supported Saitō Yoshitatsu in the Battle of Nagaragawa against Yoshitatsu’s father, Dōsan. After the death of Yoshitatsu, Morinari served Saitō Tatsuoki. Tatsuoki, however, favored only certain of his senior retainers. Morinari, along with Yoshimichi and Naomoto, became estranged from their new lord and did not listen to his admonitions. In 1564, Morinari launched a rebellion during which his son-in-law, Takenaka Shigeharu, took over Inabayama Castle. Morinari secured and occupied the area below the castle with an army of two thousand men. Later, however, he allowed Tatsuoki to return to Inabayama Castle owing to the inability of Shigeharu to gain the support of Saitō retainers.
In 1567, Morinari conspired with Yoshimichi and Naomoto in regard to the invasion by the Oda into Mino, deciding to become retainers of Nobunaga. They participated in the march upon Kyōtō in 1568, and the Battle of Anegawa in 1570. In the attack on Ise-Nagashima in 1571, Ujiie died while serving as a rear guard for the invading forces, while Morinari sustained wounds.
Morinari served in the unit directly under Nobunaga in numerous battles, including, in 1573, the Siege of Makishima Castle and attack on the Asakura clan in Echizen; and, in 1574, the battle to annihilate uprisings by the Ikkō sect in Ise-Nagashima and the attack on the Ishiyama-Hongan Temple. In 1575, Nobunaga transferred responsibility for the clan to his son, Oda Nobutada, and Morinari continued in service to the Oda by directly supporting Nobutada along with almost all of those in Mino.
In 1577, Morinari joined forces supporting an excursion by Shibata Katsuie into Kaga Province; in 1578, he participated in the attack on Kanki Castle in Harima Province on behalf of Toyotomi Hideyoshi’s campaign in the western provinces; and, later that same year, contributed to the Siege of Arioka Castle following a rebellion by Araki Murashige.
In 1580, Morinari was suddenly suspected of having ambitions against Nobunaga, and, together with Hayashi Mitsuhide and Niwa Ujikatsu, reprimanded and expelled from the clan. Nobunaga’s concerns may have arisen from Morinari’s origin as a former enemy of the Oda with influence in Mino, in addition to concern that Morinari and the others aimed to take advantage of Nobunaga during a period of sustained conflict. Those dismissed included Morinari’s youngest brother, Andō Satouji.
In 1582, Nobunaga died in a coup d’état led by Akechi Mitsuhide known as the Honnō Temple Incident. Morinari, together with his son, Sadaharu, raised arms and attacked Kitagata Castle in the Mushiroda District of Mino, only to lose in a counterattack by Inaba Yoshimichi, lord of the castle. This led to the entire family committing suicide and the end of the Andō clan.
