Robert Fabyan (died 1513), chronicler, was born in London, of which he became an Alderman and Sheriff. He kept a diary of notable events, which he expanded into a chronicle, which he entitled The Concordance of Histories. It covers the period from the arrival of Brutus in England to the death of King Henry VII of England, and deals mainly with the affairs of London. It was not printed until 1515, when it appeared under the title of The New Chronicles of England and France.
He was apprenticed as a draper to William Holme about 1470, and was granted the freedom of the Company in 1476. In 1485 he served as renter warden of the Drapers, and in 1486 as auditor of the accounts of the City of London. In 1493 he was elected Sheriff, and in the following year as alderman of the ward of Farringdon Without. In 1495 he was elected Master of the Drapers, and in 1496 was chosen to petition Henry VII on behalf of the Company with respect to the levies on cloth exported from England to Flanders. During the Cornish Rebellion of 1497 Fabyan, John Brooke and John Warner were charged with securing Ludgate and Newgate. After the suppression of the rebellion they travelled with the King to Woodstock. In 1498 he was one of the assessors of a subsidy levied to finance the war in Scotland. In 1501 he was again elected Master of the Drapers. In 1503 he resigned his office of alderman on the ground that he lacked the financial resources to support election as Lord Mayor.
