History
Construction

In 1755, Thomas Williams and John Cooley made a survey to find a suitable route for a man-made waterway across north Leinster from Dublin to the Shannon. They originally planned to use a series of rivers and lakes, including the Boyne, Blackwater, Deel, Yellow, Camlin and Inny and Lough Derravaragh. A disgruntled director of the Grand Canal Company sought support to build a canal from Dublin to Cloondara, on the Shannon in West County Longford.
Work on this massive project commenced in May 1790 at Cross Guns Bridge,

in a westerly direction towards
Ashtown. This is commemorated in the plaque beneath the keystone of Ranelagh Bridge.
Thomas James Rawson, in his 1807 ''Statistical Survey of the County of Kildare'' describes the state of completion of the canal at the time, with 3,000 men in constant employment.
In 1817, twenty-seven years after it began, the canal reached the Shannon. The total cost of construction was £1,421,954. Building was unexpectedly expensive, and the project was riven with problems; in 1794 the Royal Canal Company was declared bankrupt. The Duke of Leinster, a board member, insisted that the new waterway take in his local town of

. The builders had to deviate from the planned route; this necessitated the construction of a 'deep sinking' between Blanchardstown and Clonsilla. The diversion also called for the building of the Ryewater Aqueduct, at Leixlip.

In 1796, the canal reached

and trade commenced. Two passenger boats, the ''Camden'' and the ''Phelan'', went into service on 2 December 1796, with a fare of

In the late 1820s, as the quality of
roads in Ireland improved, road carriers such as
Bianconi's Coach and Car Service began to compete with the canal as an affordable alternative public transport option.
By the 1830s the canal carried 80,000 tons of freight and 40,000 passengers a year.

company was formed by an act of Parliament, the
Midland Great Western Railway of Ireland Act 1845 (
8 & 9 Vict. c. cxix) authorising it to build a railway from Dublin to and and to purchase the Royal Canal, which they did that same year. They considered draining the canal and building a new railway along its bed; however they were "legally obliged to operate the canal as a separate transport system and so it (the Royal Canal) continued to operate". The train line was eventually laid adjacent to the canal, and the two run side by side from Dublin to Mullingar.

The tenants, who would become known locally as the "Missing 1,490", had been offered a choice of emigration with assisted passage, starvation on their blighted potato farms or a place in the local workhouse.

It is estimated that half of the emigrants died before reaching Grosse-Île. This was the largest single exodus of tenants during the Famine.

Competition from the railways gradually eroded the canal's business, and by the 1880s annual tonnage was down to about 30,000 and the passenger traffic had all but disappeared.
The canal had a brief resurgence during

took over the canal in 1944. As rail and road traffic increased, the canal fell into disuse. In 1951, one boat was left using the canal commercially, which ceased in July of that year. A decade later, in 1961, CIÉ closed the navigation on the canal, and placed a dam across it "three miles west of Mullingar, thereby cutting off the main water supply to the western section".
In 1974, volunteers from the Inland Waterways Association of Ireland formed the Royal Canal Amenity Group to save the canal. By 1990 they had 74 kilometres of canal, from the 12th lock in Blanchardstown to Mullingar, open again for navigation. In 2000, the canal was taken over by Waterways Ireland, a cross-border body charged with administering Ireland's inland navigations. On 1 October 2010, the whole length of the canal was formally reopened.
Management
Since the early 19th century, the canal has been maintained by eight successive agencies: the Royal Canal Company, the Commissioners of Inland Navigation, the New Royal Canal Company,
Midland Great Western Railway Company,
