1265
1265 may refer to the year 1265 CE or to the integer 1265. In the history of England, 1265 was a pivotal year during the Second Barons’ War. In January a Parliament assembled at Westminster under the de facto leadership of Simon de Montfort. This assembly is often cited as the first English Parliament to include representatives of the common people, with two knights from each shire and two burgesses from each borough. The Parliament’s creation of a lasting representative precedent influenced the later development of the English constitutional system. In August 1265 the conflict culminated at the Battle of Evesham, where Montfort’s forces were defeated by the royal army led by Prince Edward (later King Edward I). Montfort was killed in the battle, and his faction’s influence ended, though some of its reforms shaped later constitutional developments.
