Isabella of England (1214 – 1 December 1241) was an English princess of the House of Plantagenet. She became Holy Roman Empress, Queen of Sicily, Italy and Germany from 1235 until her death as the third wife of Emperor Frederick II. Life Birth and early years Isabella was born around 1214 as the fourth child and second daughter of John, King of England and his second wife Isabella of Angoulême. Her exact date of birth is unknown, and the year is calculated based on the fact that Matthew Paris reported that the princess got married at the age of 21.

From time to time, the princess with her family visited other royal residences: Winchester, Marlborough, Northampton, York and others.
