系谱

他是圆融天皇的第一皇子，母亲是藤原兼家之女诠子。一条天皇的父帝圆融天皇除了他以外，没有其他子女，因此一条天皇为独生子。

略历

永观2年（984年），还在花山天皇的时代，就被立为皇太子。986年8月1日，因为花山天皇出家，七岁的皇太子即位（一说是兼家为了让孙子早点即位而实行的阴谋）。立冷泉天皇的皇子居贞亲王（三条天皇）为皇太子，摄政由藤原兼家担任（之后为关白）。

兼家死后由长男道隆等外戚继续担任摄政与关白，并且让女儿定子入宫做皇后，道隆于长德元年（995年）病逝。取而代之的是由其弟道兼就任关白，但他七天后也死了，之后道隆之子伊周与道隆、道兼之弟道长相争，道长得到胜利，掌握实权。道长将女儿彰子也送入宫，成为与皇后定子位阶相等的中宫，开了一帝二后的先例。

一条天皇的时代，也是道隆、道长兄弟与藤原氏权势达到顶峰的时代，而服侍皇后定子的清少纳言与服侍中宫彰子的紫式部、和泉式部等人，使平安时代女流文学得到发展。天皇本人对文艺方面也相当关心，留下《本朝文粹》等诗文。他对音乐也很有专长，擅长吹笛。此外，他为人温和而好学，得到很多人的仰慕。

Biography

Before he ascended to the Chrysanthemum Throne, his personal name (imina) was Kanehito-shinnō (懐仁).

Kanehito-shinnō was the first son of Emperor En'yū and Fujiwara no Senshi, a daughter of Fujiwara no Kaneie. Since there are no documented siblings, it is supposed that he was an only child.

Ichijō had five Empresses or Imperial consorts and five Imperial sons and daughters.

Events of Ichijōs life

His reign coincided with the culmination of Heian period culture and the apex of the power of the Fujiwara clan. He ascended to the throne after a period of political instability that began within the Fujiwara clan after they successfully eliminated the Minamoto clan as a political rival. The internal power struggle that ensued within the Fujiwara saw the untimely ends of three emperors. Ichijō had been appointed crown prince under Emperor Kazan in 984. Two years later, after Emperor Kazan abdicated in 986, Ichijō ascended to the throne at the age of six. The young Emperor Ichijō was under the influence of his uncle Fujiwara no Michinaga from the start of his reign, though Michinaga's true ascent to political dominance did not begin until 995 after the deaths of his older brothers and the exile of his political rival and nephew, Korechika.

These events took place during the Kanna era (see Japanese era name nengō 年号), after Emperor Kazan abdicated. The succession (senso) was received by a cousin, the son of his father's younger brother.

• August 1, 986 (Kanna 2, 23rd day of the 6th month): Emperor Ichijō is said to have acceded to the throne (sokui).

A son of Emperor Reizei, who was older than Ichijō, was appointed crown prince. Kaneie became the regent (Sesshō) and effectively ruled the state. After Kaneie died in 990, his first son and Ichijō's uncle Fujiwara no Michitaka was appointed regent.

• March 1, 991 (Shōryaku 2, 12th day of the 2nd month): The former-Emperor En'yū died at the age of 33.

• 1008 (Kankō 5, 8th day of the 2nd month): Kazan died at the age of 41.

• July 16, 1011 (Kankō 8, 13th day of the 6th month): In the 25th year of Emperor Ichijō's reign (一条天皇二十五年), the emperor abdicated; and the succession (senso) was received by his cousin. Shortly thereafter, Emperor Sanjō is said to have acceded to the throne (sokui).

• July 19, 1011 (Kankō 8, 16th day of the 6th month): Emperor Ichijō takes tonsure as a Buddhist monk.

• July 25, 1011 (Kankō 8, 22nd day of the 6th month): Emperor Ichijō died.

The mother of the emperor had a large influence over the appointment of officials, "the emperor's officials controls matters of the state, as the imperial mother makes affairs of the court solely her own."

Ichijō had two empress consorts. First was Teishi (or Fujiwara no Sadako), a daughter of Fujiwara no Michitaka. Second was Shōshi (or Akiko), a daughter of Fujiwara no Michinaga, a younger brother of Michitaka. Most people thought it impossible to have two empress consorts, but Michinaga claimed that the empress held two separate titles, Chūgū and Kōgō, which were different in principle and could therefore given to two different women.

The courts of both empresses were known as centers of culture. Sei Shōnagon, author of The Pillow Book, was a lady in waiting to Teishi. Murasaki Shikibu was a lady in waiting to Shoshi. There were other famous poets in the courts of the empresses.

Ichijō loved literature and music. For this reason, high ranked courtiers felt the necessity for their daughter to hold cultural salons with many skillful lady poets. Particularly he was fond of the flute. Ichijō was known for his temperate character and was beloved by his subjects.

During Ichijō's reign, Imperial visits were first made to the following four shrines: Kasuga, Ōharano, Matsunoo, and Kitano; and in the years which followed, Emperors traditionally made yearly Imperial visits to these shrines and to three others: Kamo, Iwashimizu and Hirano.

The actual site of Ichijō's grave is known. This emperor is traditionally venerated at a memorial Shinto shrine (misasagi) at Kyoto.

The Imperial Household Agency designates this location as Ichijō's mausoleum. It is formally named En'yū-ji no kita no misasagi.

Ichijō is buried amongst the "Seven Imperial Tombs" at Ryōan-ji Temple in Kyoto. The mound which commemorates the Emperor Ichijō is today named Kinugasa-yama. The emperor's burial place would have been quite humble in the period after Ichijo died.

These tombs reached their present state as a result of the 19th century restoration of imperial sepulchers (misasagi) which were ordered by Emperor Meiji.
