Rugby football is the collective name for the team sports of rugby union and rugby league.

Canadian football and, to a lesser extent, American football were once considered forms of rugby football, but are seldom now referred to as such. The governing body of Canadian football, Football Canada, was known as the Canadian Rugby Union as late as 1967, more than fifty years after the sport parted ways with rugby rules.

Rugby football started about 1845 at Rugby School in Rugby, Warwickshire, England, although forms of football in which the ball was carried and tossed date to the Middle Ages (see medieval football).[4] Rugby football spread to other English public schools in the 19th century and across the British Empire as former pupils continued to play it.

In 1999, Lord Portman became the 10th Viscount and began work on rejuvenating the Estate.

Over the last 20 years, the development of the Estate has gone from strength to strength. We actively manage the property assets, both directly as a landlord to an ever-increasing number of residential and commercial customers, and through our relationships with long-term leaseholders.

We aim to be at the forefront of

property management and placemaking in Central London. This is an example of how an estate can combine a modern, agile and forward-thinking approach to its activities, while remaining loyal to its history, heritage and values.

The Portman Estate dates back to the 16th century, when Sir William Portman, Lord Chief Justice to King Henry VIII,^[5] and originally from Orchard Portman in Somerset, leased 270 acres of the Manor of Lileston (Lisson). He acquired the freehold in 1554, but most of the land remained farmland and meadow until the mid-18th century and the building boom after the end of the Seven Years' War in 1763.

In the 1750s William Baker had leased land from the family to lay out Orchard and Portman Streets, and the north side of Oxford Street. Henry William Portman, a descendant of Sir William, continued the development in 1764 with the creation of Portman Square, with buildings by James Wyatt, Robert Adam and James 'Athenian' Stuart, including Montagu House, built in the north-west corner for the famed literary hostess Elizabeth Montagu and later used by the Portman family as their London town house.

Portman Square was the focus of the new estate and was followed by the building of Manchester Square during the 1770s and Bryanston and Montagu Squares 30 years later. These were laid out by the Estate's architect, James Thompson Parkinson. The area remained largely residential, attracting the prosperous middle class who wanted to live near the centre of London. There were also mews for tradesmen and servants. At the southwest corner of the Estate, where Marble Arch now stands, was the Tyburn gallows, London's principal place of public execution until 1783.

Development of the area north of the Marylebone Road around Dorset Square continued after 1815, and to the North West in Lisson Green, workers’ cottages were built from 1820 to 1840. Many of the original Georgian houses north of Portman Square were redeveloped as mansion blocks, which were let on long leases. This development spread along the major traffic routes of Edgware Road and Baker Street.

In 1948 the Estate, then valued at £10 million, was subject to death duties of £7.6 million on the death of the seventh Viscount Portman, resulting in the sale of all the family's West Country estates as well as the northern part of the London Estate in 1951, and the area around Crawford Street the following year. In the later 1950s and 1960s the Estate collaborated with the developer Max Rayne to redevelop the frontage of Oxford Street and Baker Street, as well as the south and west sides of Portman Square.
