English: Emperor Shomu did not have a male successor to succeed to the throne, thus female Emperor, Empress Koken succeeded to the throne.
Japanese: 聖武天皇は、皇位継承すべき男子を残せず、女性の孝謙天皇が後を継いだ。
English: After that, Emperor Tenmu's grandchild, Emperor Junnin succeeded to the throne upon the strong recommendation of FUJIWARA no Nakamaro, however he was involved in the FUJIWARA no Nakamaro dispute, Emperor Junnin was removed from his position, Empress Koken was enthroned again to become Empress Shotoku.
Japanese: その後、藤原仲麻呂の強い推挙により天武の孫の淳仁天皇が立ったが、藤原仲麻呂の乱に連座して淳仁は廃帝となり、孝謙が再度即位して称徳天皇となった。
English: During this time, other Imperial members attempted to succeed to the throne, however it was considered as a coup each time, as there was no appropriate successor to succeed to the throne.
Japanese: この間、他の皇族が皇位を狙ったがその都度謀叛と見なされ、適当な皇位継承者は不在となってしまった。
English: Due to this, Emperor Shotoku, who deeply believed in Buddhism, attempted to allow the monk, Dokyo to succeeded to the throne, (there was another theory) but he failed, Emperor Shotoku died before deciding the successor, and the Imperial line of Emperor Tenmu was decided to discontinue.
Japanese: そのため、仏教に深く帰依していた称徳は僧道鏡を皇位に付けることを企図した（異説あり）が失敗し、後継を決めないまま称徳は没し、天武皇統が断絶することとなった。
English: As a principle rule of the Imperial succession during the period between Emperor Tenmu and Emperor Shotoku was to succeed the throne from the direct Imperial line. (There was an example of having an Empress in case of the appropriate successor was too young to succeed to the throne.)
Japanese: 天武から称徳に至るまでの皇位継承のルールは（承継すべき者が未成人などの場合には女帝が中継することもあったが）、原則として直系承継であった。
English: Although this rule prevented severe disputes due to Imperial succession and stopped Emperor Tenji's Imperial line from returning, it in fact limited the successors of Imperial succession and caused the discontinuity of the Imperial family line. (As a result of this, Emperor Tenji's Imperial line was restored.)
Japanese: このルールは、激しい皇位承継紛争を未然に防止して天智皇統の復活を阻止しようとした代わりに、承継候補者を限定してしまったため、却って皇統の断絶（結果的には天智皇統の復活）という結果を招くこととなった。
English: After Emperor Shotoku died, there was an incident of the discontinuity in the Imperial line, the Ministers had a meeting and it was decided for elderly Emperor Konin, who was the grandchild of Emperor Tenji, to succeed to the throne.
Japanese: 称徳崩御による皇統断絶の危機に際して大臣らは協議を行い、その結果、天智の孫に当たる年配の光仁天皇が皇位承継することとなった。
English: It seemed like the example of Emperor Keitai was strongly considered in two issues at this time.
Japanese: また、この時には2つの点で継体天皇の先例が強く意識されていたようである。
English: One issue was it should be someone from the Imperial family line, another issue was it should be someone who has a maternal relationship to the former Emperor. (Emperor Konin was the husband of Emperor Shotoku's half younger sister)
Japanese: 一つは必ず皇胤である事、もう一つは先代の天皇との婚姻関係を有する（光仁は称徳の異母妹の夫）ことであった。
English: After learning about the experience of the discontinuity in Emperor Tenmu's Imperial line, Emperor Konin appointed his son, Emperor Kanmu as his successor, Kanmu's younger brother, Imperial Prince Sawara was chosen as the second successor of the Crown Prince.
Japanese: 光仁は天武系断絶を教訓として息子の桓武天皇を後継とし、その弟の早良親王を桓武の皇太弟とした。
English: Due to this, direct Imperial succession since Emperor Tenji and Emperor Tenmu, was not allowed, in fact Imperial succession between the eldest brothers was restored (even though it was only temporary).
Japanese: これにより、天智・天武以来の直系皇位継承は放棄され、大兄制が（一時的とは言え）事実上復活したと見ることも可能である。
English: However Imperial Prince Sawara was under suspicion of treason (the plot to assassinate FUJIWARA no Tanetsugu) and he was not allowed to succeed to the throne, he was furious about this and he ended up fasting until he died of starvation.
Japanese: だが、早良親王は謀叛の疑い（藤原種継暗殺事件）によりこれを廃し、早良は怒りもあらわに絶食死を遂げる事になる。
English: After Imperial Prince Sawara died heroically, Emperor Kanmu was scared and suffered from the Prince's curse for a long time, since Emperor Kanmu's era started as the Heian court, the respective title of Emperor Sudo was given to Imperial Prince Sawara.
Japanese: この壮絶な早良の死はその後の桓武を苦しめ、崇道天皇の号が贈られたが、桓武に始まる平安朝は長く早良の怨霊に恐れ苦しむこととなる。
English: After Emperor Kanmu's era, his eldest son, Emperor Heizei succeeded to the throne, his younger brother, Imperial Prince Kamino (later called Emperor Gosaga) became the second successor to the Crown Prince by following the Emperor's will after the Emperor Heizei, who was born weak.
Japanese: 桓武の後は、桓武長子の平城天皇が皇位継承し、その遺志に従う形で病弱であった平城の次にはその弟の神野親王（後の嵯峨天皇）が皇太弟に立った。
English: Emperor Heizei opposed this and tried to have his eldest brother in his direct Imperial line, succeed to the throne, after that he passed the throne to Emperor Saga and allowed his own son, Imperial Prince Takaoka to become Crown Prince.
Japanese: これに不満を抱いた平城は大兄である自分の直系に皇位継承することを企図して、一旦、嵯峨へ譲位して自身の子、高岳親王を皇太子とした。
English: Because of this arrangement, there was an armed dispute between Emperor Heizei and Emperor Saga, and Emperor Saga won (The Kusuko Incident).
Japanese: この措置に今度は嵯峨は反発し、平城と嵯峨の武力衝突が起こり嵯峨が勝利した（薬子の変）。
English: Due to this the direct Imperial line, Emperor Heizei lost the possibility to succeed to the throne, Emperor Saga was afraid of being criticized from both inside and outside the palace, he hesitated to appoint his own child to succeed to the throne, he appointed his younger brother, Imperial Prince Otomo (later called Emperor Junna) to become the second successor of the Crown Prince.
Japanese: これによって平城の直系は皇位の可能性がなくなったものの、嵯峨は内外の批判を恐れて自分の実子を擁立する事に躊躇して弟の大伴親王（後の淳和天皇）を皇太弟とした。
English: To prevent the dispute against Emperor Saga of Imperial succession, there was an agreement to share Imperial succession from both direct Imperial lines, in fact, the succession was conducted such as Emperor Saga - Emperor Junna - Emperor Ninmyo (Emperor Junna's child), after Emperor Ninmyo, Imperial Prince Tsunesada (Emperor Junna's child, his mother was Emperor Saga's Princess) was appointed as Crown Prince.
Japanese: 嵯峨と皇位継承紛争を防ぐために、それぞれの直系を互いに皇位につける迭立（てつりつ）を採用することとし、実際、嵯峨－淳和－仁明天皇（嵯峨の子）と皇位継承され、仁明の次も恒貞親王（淳和の子、母は嵯峨の皇女）が皇太子に立てられていた。
English: After this arrangement however, Emperor Junna was concerned it would cause another dispute, he advised Emperor Saga to appoint Emperor Ninmyo's Prince as a successor after the Emperor Ninmyo, however this advice was rejected.
Japanese: これに対して淳和は却って紛争の原因となる事を危惧を抱いており、嵯峨に仁明の次にはその皇子を立てるべきであると忠告したものの受け入れられなかった。
English: Just after both Retired Emperors Junna and Sage died one after another, Imperial Prince Tsunesada's position as Crown Prince was taken, (the Showa Disturbance) and Imperial succession was unified by Emperor Saga - along Emperor Ninmyo's Imperial line.
Japanese: しかし、淳和・嵯峨両上皇の相次ぐ崩御の直後、恒貞を廃太子（皇太子を廃すること）とする事件（承和の変）が起こり、皇位継承は嵯峨－仁明の系統に統一されることとなった。
English: There was another theory that Emperor Ninmyo caused the disturbance to unify the Imperial line of Imperial succession with the support of the Northern House of the Fujiwara clan.
Japanese: この事件は皇統統一を狙った仁明が、藤原北家の協力を得て起こしたとする説もある。
English: Therefore, after Emperor Tenji's Imperial line learned its lesson from Emperor Tenmu's Imperial line and since the era of Emperor Konin, the Imperial throne was succeeded between brothers (the practical return of the succession between the eldest brothers), and it was responsible for a continuous dispute for Imperial succession, starting from the incident to assassinate FUJIWARA no Tanetsugu and ended with the Showa Disturbance.
Japanese: かくして光仁以来の天智系皇統が天武系皇統を教訓にして取り入れた兄弟継承の相続（大兄制の実質復活）は、藤原種継暗殺事件から承和の変に至る皇位継承を巡る内紛の連鎖の招来に終わった。
English: After the era of Emperor Ninmyo, Imperial succession of the direct Imperial line continued almost smoothly for example; Emperor Montoku - Emperor Seiwa - Emperor Yozei, later Emperor Yozei caused a serious incident in the Palace, (there was a theory about him accidentally killing someone) after he was forced to abdicated from the throne, and again there was a crisis of the discontinuity of Imperial succession of the direct Imperial line.
Japanese: 仁明の後、文徳天皇－清和天皇－陽成天皇と直系による皇位継承がほぼ順調に行われたが、陽成が内裏で重大事件（誤って殺人を犯したとする説が有力）を起こし退位に追い込まれてしまい、再び直系継承の下で皇統断絶の危機が訪れることになった。
English: At this time there wasn't an appropriate successor and Imperia Prince Tsunesada, who had previously lost his position as Crown Prince, and Emperor Saga's child, MINAMOTO no Toru, were both appointed as successors, finally it was decided in favor of Emperor Ninmyo's child, Emperor Koko who was rather old to become a successor, became Emperor after following the example of when Emperor Shoko died.
Japanese: このときは、有力候補がおらず、廃太子となった恒貞親王や嵯峨の子である源融らが候補となったが、最終的には称徳崩御時の先例をとって、仁明の子で年配の光孝天皇が即位して皇位を継いだ。
English: However, Emperor Koko succeeded to the throne temporarily and he allowed all his children to be demoted to commoners; as he did not decide upon a successor before his death, Emperor Koko's child MINAMOTO no Sadami was hurriedly made Crown Prince as an emergency measure just prior to the emperor's death and he subsequently succeeded to the throne as Emperor Uda.
Japanese: ただ、光孝はあくまで中継ぎとの立場をとり、自身の皇子を全て臣籍降下させていたが、死去直前になっても後継者を立てていなかったため、緊急措置として急遽、光孝の子の源定省が立太子され宇多天皇となった。
English: It was an unusual example of Japanese Imperial succession for an Imperial member who had been demoted from nobility to subject, to come back and succeed the throne, it was forced to decision because the Emperor had the absolute right to chose the rank of the Emperor's children.
Japanese: 一度臣籍に下った者が皇位につくのは、日本の皇位継承史の中でも極めて異例であるが天皇の子の身分の決定は天皇の専権事項である（臣籍に降ろした実子を皇族に戻す事も許される）として押し切ったのである。
English: But, Emperor Uda and his child, Emperor Daigo established the form of the Emperor's directly ruled government by actively becoming involved in politics.
Japanese: しかし、宇多とその子の醍醐天皇は積極的な政治を展開し、天皇親政の理想型を築いた。
English: Since the era of Emperor Montoku, the Northern House of the Fujiwara clan became Regent and Chancellor as the Emperor's maternal relatives and the regency government was partly established, during the era of Emperor Daigo's child, brothers of the Emperor Suzaku and Emperor Murakami, this government was fully established.
Japanese: 文徳天皇の頃から藤原北家が天皇の外戚として摂政・関白につく摂関政治がある程度形成されていたが、醍醐の子である朱雀天皇・村上天皇兄弟の頃に、摂関政治が確立することとなる。
English: Within the regency family, there were some candidates for Regent and Chancellor that came forward, each candidate sent their daughter to the Imperial Palace to become the Emperor's consort and those daughters had children, there were power struggles, between the regency families, to control Imperial secession.
Japanese: 摂関家内部に複数の摂関候補者が登場することとなり、それぞれの候補者が別個に天皇に娘を入内させて子をもうけたため、皇位継承は摂関家のパワーバランスに左右されることとなった。
English: Due to the above, there were many candidates for Imperial succession, again, the separation of the Imperial line - sharing the Imperial throne - became apparent.
Japanese: 以上のような状況から、皇位継承候補者も複数存在することとなり、再び皇統の分裂－迭立－が見られるようになった。
English: After FUJIWARA no Michinaga combined the line of regency family into one, the Imperial line was also unified into one.
Japanese: しかし、藤原道長が摂関家を統一したことに伴い、皇統も統一されることになる。
English: Thereafter, although there was a tendency to share the Imperial throne, there was intention inside the Imperial Palace to unify the Imperial line for succession.
Japanese: その後も迭立への動きは見られたが、王朝内部に皇統を統一する意思が働き続けた。
English: Emperor Gosanjo had planned to pass the throne to a male successor of his direct line before he retired, and he tried to rule politics as an retired Emperor in order to establish a strong basis for unifying the Imperial line.
Japanese: 後三条は、皇統統一をより強固なものとするため、生前に直系男子へ譲位し上皇として政務に当たることを目論んでいた。
English: Emperor Gosanjo died before his plan could be realized, his male successor, directly in line, Emperor Shirakawa abided by Emperor Gosanjo's will and he became the retired Emperor and started the Cloistered government to rule politics as the actual Emperor (Chiten no Kimi).
Japanese: 後三条はその実現の前に没したが、その直系男子の白河天皇は後三条の遺志を継いで、上皇となって事実上の国王（治天の君）として政務に当たる院政を開始した。
English: As the retired Emperor acted as Emperor, the Emperor himself filled the current position of Crown Prince, there often was no one to become Crown Prince.
Japanese: 上皇が国王の座につくことにより、天皇がそれまでの皇太子的立場となったため、皇太子の空位が常態化した。
English: In the late Heian period, the dispute about Imperial succession to the Retired Emperor Toba happened, Emperor Sutoku, Emperor Konoe, and Emperor Goshirakawa, between brothers, opposed to each other, but, it was settled by armed conflict after the Hogen War, the Heiji War.
Japanese: 平安末期になると、鳥羽上皇の後継をめぐって崇徳天皇、近衛天皇、後白河天皇の兄弟間による皇位承継紛争が保元の乱・平治の乱という武力衝突により解決されることとなった。
English: Emperor Goshirakawa finally won the War, however, since he used Samurai to win, this allowed Samurai to become involved in politics later on.
Japanese: 最終の勝利者は後白河であったが、両乱を通じて武士を利用したため、その後の武士の台頭を許すこととなった。
English: After the era of Emperor Goshirakawa, the successors to the Imperial throne were from many different Imperial lines, but Emperor Goshirakawa continued to rule the government as In (Chiten no Kimi, the retired emperor), due to this the Imperial line was, in a way, secured.
Japanese: 後白河の後、皇位継承者は非常に多くの系統に分かれたが、後白河が院＝治天の君として君臨し続け、むしろ皇統は安定していたといえる。
English: Emperor Goshirakawa tried to maintain the power of the Imperial Palace against the sudden rise of the Samurai forces such as Ise-Heishi (Taira clan) and Kawachi-Genji (Minamoto can), however he had to pass part of the Imperial Palace authority to the Kamakura bakufu (Japanese feudal government headed by a shogun).
Japanese: 後白河は伊勢平氏・河内源氏など武士勢力の勃興に対して、王権の維持を図ろうとしたが、結局、王権の一部を鎌倉幕府へ委譲することとなる。
English: Since Emperor Goshirakawa's proper successor was Emperor Gotoba, the Imperial line was unified along Emperor Gotoba's line, after Emperor Goshirakawa died, Emperor Gotoba started his Cloistered government.
Japanese: 後白河の正当な後継者は後鳥羽天皇であり、皇統は後鳥羽の系統に統一され、後白河の死後、後鳥羽は院政を開始した。
English: Emperor Gotoba caused the Jokyu Disturbance in order to take back the right to govern the eastern states from the Kamakura bakufu, however, the result was that the Imperial Palace lost the battle against the Kamakura bakufu.
Japanese: 後鳥羽は鎌倉幕府に移った東国統治権を奪還するべく承久の乱を起こしたが、王朝が幕府に破れるという事態を招いた。
English: Consequently, the Imperial line of Emperor Gotoba's Cloistered government and Emperor Gotoba were abolished, and this caused a problem because there was no one to succeed to the Imperial throne.
Japanese: この結果、幕府によって後鳥羽院政と後鳥羽系統の皇統は全て廃されたが、皇位継承すべき者が不在という事態に至った。
English: At that time, a custom prevailed that the successor of the Imperial throne should have a father who was a retired Emperor, therefore Imperial Prince Morisada who previously had no position in the Imperial Palace, succeeded to the position to start to rule the Cloistered government as Gotakakurain against his will, and his son became Emperor Gohorikawa.
Japanese: 当時、皇位承継するにはその父が院でなければならないという慣例ができており、やむなく皇位についたことのない守貞親王が後高倉院として治天の地位について院政を開始し、その子が後堀河天皇として即位することとなった。
English: Unfortunately, the Imperial line of Emperor Gohorikawa discontinued after the second Emperor, Emperor Shijo died young, the Imperial throne again went back to Emperor Gotoba's Imperial lineage.
Japanese: しかし、後堀河の系統も次代の四条天皇が幼年のうちに没したことで断絶し、皇位は再び後鳥羽の系統へ戻った。
English: Emperor Gosaga's father, Emperor Tsuchimikado, was treated coldly by his own father, Emperor Gotoba, took a neutral position at the Jokyu Disturbance, it made a good impression on the Kamakura bakufu and practically all the bakufu approved Emperor Gosaga's Imperial succession to the throne.
Japanese: 後嵯峨の父は、父の後鳥羽に疎んじられて承久の乱の際も中立を守った土御門天皇であるが、このことが幕府の賛意を得ることになり、事実上、後嵯峨の皇位継承は幕府が決定したと言える。
English: This example was followed until the period of Edo bakufu (Japanese feudal government headed by a shogun), the bakufu needed to approve the Imperial succession to the throne.
Japanese: これは、後世の先例となって江戸幕府に至るまで、皇位継承には幕府の承認が必要とされた。
English: Emperor Gosaga's children, the brothers of Emperor Gofukakusa, Emperor Kameyama, both fought against each for the position of Chiten no kimi as his father's successor, they came to an agreement to conduct Ryoto Tetsuritsu (sharing the Imperial throne from both Imperial lines) that the direct descendants of the each Imperial line would take turns to sharing the Imperial throne.
Japanese: 後嵯峨の子には、後深草天皇・亀山天皇の兄弟がいたが、互いに後嵯峨後継の治天の君の座を争い、その妥結として、両者の直系子孫が交互に皇位・治天位につく両統迭立が行われることとなった。
English: The older brother, Emperor Gofukakusa's line was called the Jimyoin Imperial line, and the younger brother, Emperor Kameyama's line was called the Daikakuji Imperial line, this example of sharing the throne was the biggest event in Japanese history that had a great impact on the later period.
Japanese: 兄・後深草の系統を持明院統、弟・亀山の系統を大覚寺統というが、これが日本史上最大の皇位迭立となり、後世に大きな影響を与えることとなる。
English: The Ryoto Tetsuritsu was conducted smoothly for a while, however the Imperial lines started to divide within the each Imperial line at the end of the Kamakura period, the situation was getting confused in terms of sharing the throne.
Japanese: しばらく両統迭立は順調に行われていたが、鎌倉時代末期になると両統の内部で皇統分裂が見られ始め、迭立の混乱が生じてきた。
English: Under such circumstances, Emperor Godaigo of the Daikakuji Imperial line attempted to overthrow the Bakufu twice to revive royal authority for the Imperial Palace (the Shochu Disturbance, the Genko Disturbance), his position was taken away from the bakufu and he was banished, but it caused the ruin of the Kamakura bakufu, Emperor Godaigo became Emperor again in Kyoto and started the Kenmu Restoration.
Japanese: その状況下で大覚寺統の後醍醐天皇は、王権復興を目指して幕府追討計画を2度にわたって立て（正中の変・元弘の変）、幕府により廃位・流罪に処されるも、鎌倉幕府の滅亡をもたらし、京で復位した後、建武の新政を開始した。
English: Emperor Godaigo did not become a retired Emperor, it was the first time in the last two hundred years (for the last Emperor not to become a retired Emperor and to start a Cloistered government) that the Emperor governed his directly ruled government.
Japanese: 後醍醐は治天の地位につくことなく、約200年ぶりに天皇の地位のまま親政を行った。
English: The Emperor had the intention to solve the current problem of conducting Ryoto Tetsuritsu and re-unifying the Imperial line to his lineage, however there were many disputes against the Emperor's new government, the Ashikaga shogunate who was in opposition to the Emperor appointed Emperor Komyo from the Jimyoin Imperial line.
Japanese: 後醍醐は両統迭立状態を解消し、自身の系統に皇統を再度統一したと考えていたが、その後、後醍醐の新政へ多くの離反が相次ぎ、離反勢力からなる足利幕府は持明院統から光明天皇を擁立した。
English: Because of this, it caused two Imperial lines to emerge during the same period, the Northern Court (the Jimyoin Imperial line) and the Southern Court (Daikakuji Imperial line), which was unprecedented in the Japanese history.
Japanese: これにより北朝（持明院統）と南朝（大覚寺統）の2つの王朝が同時に存在する日本史上未曾有の事態となった。
English: The Northern Court had the support from the Ashikaga shogunate and continued ruling the Cloister government the same as before, on the other hand, in the Southern Court, after the era of Emperor Gomurakami, although the position of Chancellor had returned to the Palace, the Emperor continued to directly rule the government.
Japanese: 北朝は、幕府の擁護を受けて、従来どおりの院政を継続したが、南朝では後村上天皇以降、関白こそは復活させたものの天皇親政を貫いた。
English: In 1352, when there were internal problems within the Muromachi bakufu, the Southern Court army took the opportunity to occupy Kyoto, and abduct the main Imperial members of the Northern Court, such as Emperor Suko. (Shohei Itto)
Japanese: 1352年室町幕府内部の内紛に乗じて南朝軍が京都を占領して北朝の崇光天皇ら主だった皇族を拉致してしまう（正平一統）。
English: The Muromachi bakufu received information that the Emperor's younger brother was left at a Temple, and they allowed him to hastily succeed to the throne as Emperor Gokogon.
Japanese: 室町幕府は天皇の弟の一人が寺院に預けられている事を知って急遽後光厳天皇として即位させた。
English: Although the Southern Court forces later released Emperor Suko and others, the Muromachi bakufu did not approve Emperor Suko's return as Emperor, the bakufu tried to appeased his descendants by giving the respective title of Fushiminomiya.
Japanese: 後に南朝方は崇光らを返還したものの、室町幕府は崇光の復位を認めず子孫には伏見宮の称号を贈って宥めようとした。
English: However, after it was decided that the direct descendants of Emperor Gokogon would succeed to the throne, antagonism was raised against Emperor Gokogon and the Muromachi bakufu by Emperor Suko and the Fushiminomiya family, and this practically caused a division within the Northern Court.
Japanese: だが、皇位継承が後光厳の直系子孫による方針が決められたために崇光と伏見宮家による後光厳と室町幕府に対する反感が高まって、北朝は事実上の分裂状態に陥ったのである。
English: As time went by, when it became apparent the Northern Court and the Muromachi bakufu were in the superior position, the Southern Court started looking for an agreement.
Japanese: 時代が進み北朝・室町幕府側の優位が明確になってくると、南朝側も妥結点を模索してきた。
English: In 1392 after the suggestion to restart the sharing of the Imperial throne between the Jimyoin Imperial lineage (the Northern Court) and the Daikakuji Imperial lineage (the Southern Court), Emperor Gokameyama of the Southern Court accepted, and the unity of the Northern Court and the Southern Court was realized, together with Emperor Gokomatsu of the Northern Court.
Japanese: 1392年、持明院統（北朝）と大覚寺統（南朝）の迭立再開が提案され、南朝の後亀山天皇が条件受諾したことにより、北朝の後小松天皇とともに南北朝合一が実現した。
English: However after Emperor Shoko succeeded to the throne in 1412, the agreement to restart sharing the Imperial throne was cancelled, there was a declaration for Emperor Gokomatsu's direct descendants to succeed to the throne.
Japanese: しかし、1412年に称光天皇が即位するに際して迭立再開の条件は撤回されることとなり、後小松天皇の直系子孫による皇位継承が宣言された。
English: The Southern Court was furious after the agreement for sharing the Imperial throne was cancelled, they continued to stay as Gonancho (the Southern Court in later years) in later years. (There were some people who named themselves as the descendants of the Southern Court after the Pacific War.)
Japanese: 約束を反故にされた南朝側は憤慨し、後南朝としてその後も存続し続けた（太平洋戦争後まで南朝子孫を名乗る者がいた）。
English: It seemed that Imperial succession was sacred at a glance with the unity of the Northern Court and the Southern Court, however, the internal trouble within the Northern Court did not become resolved.
Japanese: 一見、南北朝合一により皇位継承は再び安定したように見られたが、もう一つの問題であった北朝内部の内紛は解消されなかった。
English: Furthermore, Emperor Gokomatsu only had one male child, Emperor Shoko, (Emperor Shoko's Crown Prince, Emperor Gokomatsu's second Prince died young, and in fact, Sojun IKKYU the famous monk was Emperor Gokomatsu's Prince, he had to enter into the priesthood at a young age for political reasons, he did not have any right to succeed to the throne.) Emperor Shoko did not have any children and he was born weak, and he was not expected to live long.
Japanese: 更に後小松には称光しか男子がおらず（称光の皇太子であった後小松の第2皇子は早世、実はこの他に名僧として知られた一休宗純も後小松の皇子であったが、政治的事情により早くから出家させられて皇位継承権を失っていた）、更に称光には子供がいない上に虚弱体質であったためにいつ崩御されてもおかしくない状態となっていた。
English: Thus Emperor Gokomatsu, who was ruling the Cloistered government at the time, secretly ordered Fushiminomiya Imperial Prince Sadafusa, who was the grandchild of Emperor Suko, to succeed to the throne in the event of an emergency.
Japanese: そこで当時院政を行っていた後小松は崇光の孫である伏見宮貞成親王に対して万が一の際の皇位継承を極秘に要請した。
English: After Emperor Suko learned of the above arrangement, he was furious and had Imperial Prince Sadafusa forcefully enter into the priesthood, the Prince had his right to succeed to the throne taken away.
Japanese: ところがその話が称光に伝わると激怒して貞成親王を強引に出家させて皇位継承権を剥奪してしまった。
English: Not too long after that, Emperor Shoko died in 1428, and Emperor Gokomatsu's Imperial line discontinued.
Japanese: ところがそれから程ない1428年に肝心の称光が崩御して後小松系の皇統が断絶してしまった。
English: Then Emperor Gokomatsu allowed Emperor Gohanazono, who was the Imperial Prince Sadafusa's Prince, to succeed to the throne.
Japanese: そこで後小松は貞成親王の皇子であった後花園天皇を擁立させたのである。
English: The Southern Court was against it, and said they would not accept the Imperial succession of the Northern Court as their Imperial lineage had already discontinued, they raised revolts in many places.
Japanese: これに対して旧南朝側では北朝側の皇統は断絶しており、傍流の継承は認めないとして各地で蜂起を起こした。
English: There was a crisis that had occurred whereby some Samurai forces from the Southern Court went into the Imperial Palace and took the three sacred treasures (,Kinketsu Disturbance) later the Muromachi bakufu suppressed the story, and this was a sign that real 'unity of the Southern and the Northern Court' had come about.
Japanese: 一時は宮中に侵入した南朝側の武士によって三種の神器を奪われる（禁闕の変）などの危機にもあったが室町幕府はこれを鎮圧、ここにおいて初めて真の「南北朝合一」が実現したのである。
English: In early 1990s, it was suspected that Yoshimitsu ASHIKAGA planned to take the power back to succeed to the throne.
Japanese: 1990年代前期ごろから足利義満は皇位簒奪を企図していたとする説が注目されるようになった。
English: He was a high ranking Samurai, and also a court noble, he gradually prepared to pretend to start the Cloistered government, and he planned to have his son, Yoshitsugu ASHIKAGA succeed to the throne, however this Imperial succession did not happen as he died just before his plan was about to come to fruition.
Japanese: 武家としてだけでなく、公家としても官位を極めた義満は、治天の君としての行動を徐々に始め、自身の子である足利義嗣を皇位につけることを計画していたが、計画成就の寸前に死去したため皇位簒奪がならなかったとしている。
