Sumiyoshi Imperial Palace - Sumiyoshi no Angu

During the Nanboku-cho period, this was the temporary palace (temporary palace) of Emperor Go-Murakami and Emperor Chokei of the Southern Court. The building used for the temporary palace was called "Shoin-den" and was also known as "Suminoe-dono". The ruins of Sumiyoshi Imperial Palace are located within the grounds of Sumiyoshi Taisha Shrine in Sumiyoshi 2-chome, Sumiyoshi-ku, Osaka City, and are designated as a national historic site. When Ashikaga Takauji surrendered to the Southern Court in October 1351 (Kan'o 2, Shohei 6) due to the Kan'o Disturbance, an internal conflict within the Muromachi Shogunate, and a temporary unification of the Northern and Southern Courts (Shohei Unification) was established, Emperor Go-Murakami left Ano in February of the following year and used the residence of Tsumori Kunikika, the head priest of Sumiyoshi Shrine on the Southern Court's side, as his temporary palace. Tsumori Kunikika was awarded the rank of Shosanmi by the Southern Court. In leap February, Emperor Gomurakami advanced to Yawata in Yamashiro and attacked Kyoto, and the Southern Court forces occupied Kyoto by force, but in March Takauji and Yoshiakira, father and son, recaptured Kyoto, and Emperor Gomurakami returned to Ano from Yawata in May. Later, due to internal divisions within the Southern Court, Emperor Gomurakami moved to the Sumiyoshi temporary palace in September 1360 (Enbun 5, Shohei 15), and in October he was granted Sakai Manor at Sumiyoshi Shrine. Emperor Gomurakami died here in March 1368 (Oan 1, Shohei 23). Emperor Chokei then also used this place as a temporary palace at first, but in December he returned to Yoshino from the Sumiyoshi temporary palace.

南北朝時代、南朝の後村上天皇・長慶天皇(ちょうけいてんのう)の行宮（仮の御所）。行宮に用いられた建物は「正印殿」と称し、一名「住之江殿(すみのえどの)」とも呼ばれ、大阪市住吉区住吉2丁目の現住吉大社境内地に住吉行宮跡という遺跡があり、国の史跡に指定されている。室町幕府の内部紛争である観応の擾乱(かんのうのじょうらん)により、足利尊氏が1351年（観応2・正平6）10月南朝に降伏して、一時的な南北朝合体（正平一統(しょうへいいっとう)）が成立すると、後村上天皇は翌年2月賀名生(あのう)を出て南朝方の住吉社神主津守国夏(つもりくにか)の館を行宮とした。津守国夏は南朝から正三位に叙せられている。閏2月に後村上天皇は山城の八幡(やわた)に進んで京都を攻撃し、南朝軍は京都を武力占拠したが、3月尊氏・義詮(よしあきら)親子に京都を奪還され、5月に後村上天皇は八幡から賀名生に帰った。その後、南朝の内部分裂により、後村上天皇は1360年（延文5・正平15）9月住吉行宮に移り、10月住吉社に堺荘を安堵している。後村上天皇は1368年（応安1・正平23）3月ここで没した。ついで長慶天皇も当初ここを行宮としたが、12月には住吉行宮から吉野に還幸した。
