Following the death of Oda Nobunaga, a succession dispute erupted within the Oda clan. Shibata Katsuie backed Oda Nobutaka's claim to leadership, directly challenging Toyotomi Hideyoshi's emerging dominance. This political rivalry escalated into open military conflict when Katsuie and Sakuma Morimasa moved against Hideyoshi's fortifications at Shizugatake in Ōmi Province.
Katsuie and Sakuma Morimasa attacked Hideyoshi's fortifications at Shizugatake, defeating Nakagawa Kiyohide, while other allied sieges stalled. When Katsuie ordered Sakuma to retreat and was disobeyed, Hideyoshi launched a swift counterattack that routed Sakuma's forces. Hideyoshi then pursued the retreating army and successfully besieged Kitanosho Castle over two days in June 1583.
The fall of Kitanosho Castle resulted in the suicide of both Katsuie and Oichi, eliminating Hideyoshi's principal rival. The victory allowed Hideyoshi to firmly consolidate his position as Oda Nobunaga's successor. Historian George Sansom regarded the battle as one of the decisive engagements in Japanese history, with only the Battle of Komaki and Nagakute in 1584 remaining as a further challenge to Hideyoshi's rule.
