Taewonsu is the highest possible military rank of North Korea and is intended to be an honorific title for Kim Il-sung and Kim Jong-il. It is often confused with Marshal of the Republic and Marshal of the Korean People's Army, but ranks above both. The rank is senior to that of Wonsu. The title also exists in Chinese military history as dàyuánshuài, and was briefly taken by Sun Yat-sen.

Kim Jong Il was a North Korean politician who was the second supreme leader of North Korea. He led North Korea from the death of his father Kim Il Sung in 1994 until his death in 2011, when he was succeeded by his son, Kim Jong Un. Afterwards, Kim Jong Il was declared Eternal General Secretary of the WPK.
