Editing Emperor Uda (section)

===Historical background===

In ancient Japan, there were four noble clans, the ''[[Japanese clans|Gempeitōkitsu]]'' {{Nihongo|2=源平藤橘}}. One of these clans, the [[Minamoto clan]] {{Nihongo|2=源氏}}, is also known as Genji. Some of Uda's grandchildren were granted the surname ''Minamoto'', the most used surname for former Japanese royalty. In order to distinguish Uda's descendants from other Genji, they became known as the [[Uda Genji]] {{Nihongo|2=宇多源氏}}, some of which moved to [[Ōmi Province]] and became known as [[Sasaki clan]] {{Nihongo|2=佐々木氏}} or [[:ja:近江源氏|Ōmi Genji]] {{Nihongo|2=近江源氏}}.

Among the Uda Genji, [[Minamoto no Masanobu|Minamoto no Masazane]] {{Nihongo|2=源雅信}}, a son of [[:ja:敦実親王|Prince Atsumi]] {{Nihongo|2=敦実親王}} succeeded in the court. Masazane became ''[[sadaijin]]'' (Minister of the Left).  One of Masazane's daughters, Minamoto no Rinshi {{Nihongo|2=源倫子}} married [[Fujiwara no Michinaga]] and from this marriage three empresses dowagers and two regents (''sesshō'') were born.

From Masanobu, several [[kuge]] families originated including the Niwata, Ayanokōji, Itsutsuji, Ōhara and Jikōji. From his fourth son Sukeyosi, the Sasaki clan originated, and thus Kyōgoku clan originated. These descendants are known as Ōmi Genji today. From this line, [[Sasaki Takauji]] made a success at the Muromachi shogunate and the [[Amago clan]] originated from his brother.
