The Princess and the Queen, or, the Blacks and the Greens is an epic fantasy novella by American novelist George R. R. Martin, published in the 2013 Tor Books anthology Dangerous Women.

After Rhaenyra is crowned Queen by her followers at the Targaryen ancestral seat of Dragonstone, her second born son Lucerys Velaryon and King Aegon's younger brother Aemond both take their dragons to seek the support of Lord Borros Baratheon of Storm's End.

However, the harsh taxes she then enacts (due to the treasury being secretly emptied by the Greens supporters), as well as her vengeful lust, paranoia and subsequent summary executions of perceived traitors, trigger a violent riot in the capital, during which angry mobs fearful of dragons storm the Dragonpit and kill most of the remaining dragons (as well as Joffrey Velaryon, her last surviving son from her first marriage to Laenor Velaryon), and she is forced to flee after just half a year on the throne.

Aegon himself is rendered crippled and no longer fertile; likewise, by the ending moments of the war, Rhaenyra's three eldest children have all been killed along with her husband Prince Daemon.

According to George R. R. Martin, the Dance of the Dragons, the main conflict portrayed in The Princess and the Queen, was inspired by the 15-year-long civil war in High Medieval England known as The Anarchy, where Empress Matilda, the daughter and heir of Henry I of England, fought a protracted war of succession against her cousin Stephen from 1138 to 1153 AD, which eventually ended with the ascension of Matilda's son Henry II, the founder of the Plantagenet dynasty.
