Thomas Manners, 1st Earl of Rutland, 12th Baron de Ros of Helmsley, KG, of Belvoir Castle in Leicestershire, was created Earl of Rutland by King Henry VIII in 1525.

Belvoir Castle is a faux historic castle and stately home in Leicestershire, England, situated 6 mi (10 km) west of the town of Grantham and 10 mi (16 km) northeast of Melton Mowbray. A castle was first built on the site immediately after the Norman Conquest of 1066 and has since been rebuilt at least three times. The final building is a grade I listed mock castle, dating from the early 19th century. It is the seat of David Manners, 11th Duke of Rutland, whose direct male ancestor inherited it in 1508. The traditional burial place of the Manners family was in the parish church of St Mary the Virgin, Bottesford, situated 3 mi (5 km) to the north of the Castle, but since 1825 they have been buried in the ducal mausoleum built next to the Castle in that year, to which their ancient monuments were moved. It remains the private property of the Duke of Rutland but is open to the general public.
