The Chandos peerage was first created as a barony by Edward III in 1337; its second creation in 1554 was due to the Brydges family's service to Mary I during Wyatt's rebellion, when she also gave them Sudeley Castle.

The son of Robert, Roger de Chandos, served in the Scottish wars of Edward II and received a knighthood.

It was this Roger who was summoned to Parliament, and who was cited as Baron de Chandos between 1337 (11th year of Edward III) and 1355, counting as the first creation of the title.

George had six daughters but no sons, and after the death of his brother William in 1676 the barony came to a kinsman, Sir James Brydges, Bart., who was English ambassador to Constantinople from 1680 to 1685.

The 1st Duke built an exceptionally grand country house called Cannons in Little Stanmore, Middlesex, that, though it was parodied in his lifetime, was a seat of great learning and culture: Handel was the resident composer from 1717 until 1719.

Brydges' Cannons was demolished after his death, to pay the debts he incurred in the South Sea Bubble disaster, and by his son.

Litigation lasted from 1790 to 1803 before the claims were rejected, but Egerton Brydges continued to style himself per legem terrae Baron Chandos of Sudeley.
